PURPOSE 
MARICOPA COUNTY INTERNAL POLICY
The County strives to safeguard the health and safety of its employees by identifying and eliminating health and 
safety hazards. Employees are encouraged to prevent accidents by following safe work practices, reporting any 
unsafe work conditions, using safety equipment and personal protective equipment when instructed, maintaining 
good housekeeping habits, knowing emergency response procedures related to their work area, participating in 
applicable federal and state regulated safety training and adhering to the motto of: “Listen, Communicate and 
Take Action”
II.
BASIC HAZARD RECOGNITION
A.
County Departments shall operate and maintain facilities and equipment in a manner that reasonably assures 
that potential hazards are identified and minimized. Hazard recognition begins with the design of facilities, 
operations and selection of equipment. Applicable rules and regulations must be identified and incorporated  
in to the operating plan of each organization. Training elements for each task, piece of equipment or 
operation must be identified and risks explained to employees. Employees must be trained to recognize 
unsafe practices and conditions.
B.
The County is a diverse organization with a wide variety of operations, each of which can have unique 
risks. Each department must be able to recognize their own particular hazards by following the OSHA Five- 
Point Checklist provided as a guideline for initial hazard evaluation.
1.
Slips, trips, or falls - look for poor housekeeping, broken ladders, unguarded floor openings, over-loaded 
filing cabinets, etc.
2.
Struck - moving vehicles, unguarded machines, high noise levels, etc
3.
Caught - hazards in confined spaces, moving projectiles, material handling operations, etc
4.
Contact - flammables, acids, caustics, etc. need special consideration In addition, temperature extremes 
as well as hot and cold surfaces should be observed. Ungrounded electric tools and equipment must be 
eliminated.
5.
Breathing/Swallowing - toxic vapors and poisons.
C.
A Workplace Hazard Assessment must be conducted to establish a safe working environment. (Refer to 
Policy A2234v, Injury And Illness Prevention Plan: Workplace Hazard Assessment)
D.
Operations In The Public Right Of Way
1.
To ensure proper set up and the safest operation, employees whose job requires them to be exposed to 
traffic or work adjacent to roads must follow the most current version of the Manual of Uniform Traffic 
Control (MUTCD) and the ADOT supplement. The MUTCD and the ADOT Supplement contain the legal 
standards for traffic control devices for all jurisdictions within the State of Arizona. Refer to Arizona 
Revised Statute A.R.S. 28-641 and 28-643. Each department must develop an internal traffic control 
plan, and employees must follow that plan.

PURPOSE 
The Occupational Safety and Health Administration (OSHA) is an arm of the US Department of Labor 
created to “assure safe and healthful working conditions for working men and women by setting and 
enforcing standards and by providing training, outreach and assistance” (U.S. Dept of Labor). OSHA 
allows individual states to develop and operate their own job safety and health plans. The Arizona 
Division of Occupational Safety and Health (ADOSH) is the state-approved plan. The County is 
committed to adhering to both OSHA and ADOSH standards, whichever is more stringent.
II.
DEFINITIONS 
A.
Record Maintenance: Risk Management is responsible for maintaining and filing 
accident/injury forms (including OSHA 300 logs), medical records (as they apply to Workers 
Compensation) and supplementary information to comply with OSHA standards. (Refer to 
Policy A2219, OSHA Record Keeping Requirements)
B.
OSHA Standards: Specific OSHA standards, interpretation and their use may be obtained from 
Risk Management.
C.
Training: Mandatory training necessary to comply with OSHA standards is a critical part of the 
County's OSHA compliance program. Risk Management provides OSHA safety-training 
sessions throughout the year. Training sessions are open to all full-time, part-time and contract 
employees and volunteers. Many safety training classes and media are available from the Risk 
Management Safety Division.
III.

3.
There are special lifts where the lift director would be responsible for all the components of a lift 
including but not limited to:
a.
Lifts over 50% of the crane’s capacity
b.
2 crane lifts
4.
Center the hook over the load to keep the cables from slipping out of the drum grooves and from 
overlapping and to prevent the load from swinging when it is lifted. Inspect the drum to verify that 
the cable is in the grooves.
5.
Use a tag line when loads must travel long distances or must otherwise be controlled. Manila 
non-conductive rope may be used for tag lines.
6.
Plan and check the travel path to avoid personnel and obstructions.
7.
Lift the load only high enough to clear the tallest obstruction in the travel path.
8.
Start and stop slowly.
9.
Never leave suspended loads unattended. In an emergency where the crane or hoist has 
become inoperative and a load must be left suspended, barricade and post signs in the 
surrounding area, under the load and on all four sides. Tag out the crane.
C.
Crane shut down:
1.
Park on level ground.
2.
Set load on the ground.
3.
Retract or lower the boom to the ground if possible.

blood and can cause disease in humans. These pathogens include, but are not limited to, 
Hepatitis B virus (HBV) and human immune deficiency virus (HIV)
B.
Contaminated: The presence or the reasonably anticipated presence of blood or other potentially 
infectious materials on an item or surface
C.
Contaminated Sharps: Any contaminated object that can penetrate the skin including, but 
not limited to, needles, scalpels, broken glass, broken capillary tubes and exposed ends of 
dental wires
D.
Decontamination: The use of physical or chemical means to remove, inactivate, or destroy 
BBPs on a surface or item to the point where they are no longer capable of transmitting 
infectious particles and the surface or item is rendered safe for handling, use or disposal
E.
Engineering Controls: Controls (e.g., sharps disposal containers, self-sheathing needles) that 
isolate or remove the BBP hazards from the workplace
F.
Exposure Incident: A specific eye, mouth, other mucous membrane, non-intact skin or 
parenteral contact with blood or other potentially infectious materials that result from the 
performance of an employee's duties
G. Licensed Healthcare Professional: A person whose legally permitted scope of practice 
allows them to independently perform the activities required by paragraph (12.5) Hepatitis B 
Vaccination and Post-exposure Evaluation and Follow-up.
H.
HBV: Hepatitis B virus
I.
HIV: Human immune deficiency virus
J.
Occupational Exposure: Reasonably anticipated skin, eye, mucous membrane, or

K.
Other Potentially Infectious Materials: (1) The following human body fluids: semen, vaginal 
secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, 
amniotic fluid, saliva in dental procedures, any body fluid that is visibly contaminated with blood, 
and all body fluids in situations where it is difficult or impossible to differentiate between body 
fluids; (2) Any unfixed tissue or organ (other than intact skin) from a human (living or dead); and
(3) HIV-containing cell or tissue cultures, organ cultures, and HIV or HBV containing culture 
medium or other solutions; and blood, organs, or other tissues from experimental animals infected 
with HIV or HBV.
L.
Parenteral: Piercing mucous membranes or the skin barrier through such events as needle sticks, 
human bites, cuts, and abrasions
M. Personal Protective Equipment (PPE): Is specialized clothing or equipment worn by an 
employee for protection against a hazard. General work clothes (e.g., uniforms, pants, shirts or 
blouses) not intended to function as protection against a hazard are not considered to be PPE
N.
Regulated Waste: Liquid or semi-liquid blood or other potentially infectious materials; 
contaminated items that would release blood or other potentially infectious materials in a liquid or 
semi-liquid state if compressed; items that are caked with dried blood or other potentially 
infectious materials and are capable of releasing these materials during handling; contaminated 
sharps; pathological and microbiological wastes containing blood or other potentially infectious 
materials.
O. Research Laboratory: A laboratory producing or using research laboratory-scale amounts of HIV 
or HBV. Research laboratories may produce high concentrations of HIV or HBV but not in the 
volume found in production facilities

Casually Transmitted: Capable of being spread from one person to another, by merely being in 
close proximity to the infected individual, without requiring intimate contact to occur.
C.
Engineering Controls: Apparatuses that isolate, limit or remove airborne pathogens from the 
work place, such as respiratory isolation rooms and HEPA filters in appropriate air vents.
D.
Exposure Incident: Specific contact with a person known to be infected or suspected of being 
infected with an airborne pathogen during the performance of an employee’s duties.
E.
Mycobacterium Tuberculosis (TB): An airborne pathogen that can cause TB infection that, in 
turn, may lead to TB disease.
1.
TB Infection: An infection caused by the Mycobacterium Tuberculosis bacterium. The most 
common site for infection are the lungs (pulmonary TB); however, infection can occur in many 
body sites and systems (extrapulmonary TB). The infection is spread through the air in tiny 
droplets containing the bacterium after being expelled by persons with TB disease, primarily 
when they sneeze or cough in the case of pulmonary TB. These droplets may then remain 
suspended in the air for several hours. While the infection is casually transmitted, fairly 
intensive or prolonged exposure to a person with TB disease is generally required for TB 
infection to occur. Persons who have TB infection, but are totally free of symptoms, are not 
infectious.
2.
TB Disease: A TB infection that has overcome the defenses of the infected person’s immune 
system, and has begun to multiply and spread within the body. It is at this point that the 
infected individual will begin to show the symptoms of TB disease and become infectious to 
others. Generally, only persons with pulmonary TB disease can transmit infection to others. 
Symptoms of pulmonary TB disease include, but are not limited to, the following:

PURPOSE
This program applies to all open excavations made in the earth's surface, including trenches. 
Affected employees at the county include any employee working in or around an excavation and 
requires compliance with 29 CFR 1926 subpart P.
II.  DEFINITIONS
A.
Accepted Engineering Practices: Those requirements which are compatible with standards of 
practice required by a registered professional engineer.
B.
Benching (Benching system): A method of protecting employees from cave-ins by excavating 
the sides of an excavation to form one or a series of horizontal levels or steps, usually with 
vertical or near-vertical surfaces between levels.
C.
Cave-in: The separation of a mass of soil or rock material from the side of an excavation, or the 
loss of soil from under a trench shield or support system, and its sudden movement into the 
excavation, either by falling or sliding, in sufficient quantity so that it could entrap, bury, or 
otherwise injure and immobilize a person.
D.
Competent person: A person who is capable of identifying existing and predictable hazards in 
the surroundings or working conditions which are unsanitary, hazardous, or dangerous to 
employees, and who has authorization to take prompt corrective measures to eliminate them.
E.
Excavation: Any man-made cut, cavity, trench, or depression in an earth surface, formed by earth 
removal.
F.
Faces or Sides: The vertical or inclined earth surfaces formed as a result of excavation work.
G. Failure: The breakage, displacement, or permanent deformation of a structural member or 
connection so as to reduce its structural integrity and its supportive capabilities.
H.
Hazardous atmosphere: An atmosphere which may cause death, illness or injury by being explosive, 
flammable, poisonous, corrosive, oxidizing, irritating, oxygen deficient, toxic or otherwise harmful.
I.
Protective system: A method of protecting employees from cave-ins, from material that could fall or 
roll from an excavation face or into an excavation or from the collapse of adjacent structures. 
Protective systems include support systems, sloping and benching systems, shield systems and other 
systems that provide the necessary protection.
J.
Ramp: An inclined walking or working surface that is used to gain access to one point from

Page 2 of 8
Policy Number:
A2234n
Policy Title:
EXCAVATION PROCEDURES
Current Adoption 
Date:

another, and is constructed from earth or from structural materials such as steel or wood.
K.
Registered Professional Engineer: A person who is registered as a professional engineer in the 
state where the work is to be performed. However, a professional engineer, registered in any state is 
deemed to be a" registered professional engineer" within the meaning of this standard when 
approving designs for "manufactured protective systems" or "tabulated data" to be used in interstate 
commerce.
L.
Shield (Shield System): A structure that is able to withstand the forces imposed on it by a cave-in and 
thereby protect employees within the structure. Shields can be permanent structures or can be 
designed to be portable and moved along as work progresses. Additionally, shields can be either pre- 
manufactured or job-built in accordance with OSHA Standard 1926.652 (c) (3) or (c) (4). Shields used 
in trenches are usually referred to as "trench boxes" or "trench shields."
M. Shoring (Shoring System): A structure such as a metal hydraulic, mechanical or timber shoring 
system that supports the sides of an excavation and which is designed to prevent cave-ins.
N.
Sloping (Sloping System): A method of protecting employees from cave-ins by excavating to form 
sides of an excavation that are inclined away from the excavation so as to prevent cave-ins. The angle 
of incline required to prevent a cave-in varies with differences such as the soil type, environmental 
conditions of exposure and application of surcharge loads.
O. Stable Rock: Natural solid mineral material that can be excavated with vertical sides and will remain 
intact while exposed. Unstable rock is considered to be stable when the rock material on the side or 
sides of the excavation is secured against caving-in or movement by rock bolts or by another 
protective system that has been designed by a registered professional engineer.
P.
Structural Ramp: A ramp built of steel or wood, usually used for vehicle access. Ramps made of 
soil or rocks are not considered structural ramps.
Q. Support System: A structure such as under pinning, bracing or shoring, which provides support to an 
adjacent structure, underground installation or the sides of an excavation.
R.
Tabulated data: Tables and charts approved by a registered professional engineer and used to design 
and construct a protective system.
S.
Trench (Trench Excavation): A narrow excavation (in relation to its length) made below the surface  
of the ground. In general, the depth is greater than the width, but the width of a trench (measured at  
the bottom) is not greater than 15 feet (4.6m). If forms or other structures are installed or constructed  
in an excavation so as to reduce the dimension measured from the forms or structure to the side of the 
excavation to 15 feet (4.6m) or less (measured at the bottom of the excavation), the excavation is also 
considered to be a trench.

V.
Type C soil is cohesive soil with an unconfined compressive strength of .5tsf or less. Type C soils 
include granular soils such as gravel, sand, and loamy sand; submerged soil; soil from which water is 
freely seeping; submerged rock that is not stable; or material in a sloped, layered system where the 
layers dip into the excavation at a slope of four horizontal to one vertical or steeper.
III. GENERAL REQUIREMENTS
A.
Planning For Safety
1.
Many on the job accidents are a direct result of inadequate initial planning. Correcting mistakes in 
shoring and/or sloping after work has begun slows down the operation, adds to the cost and 
increases the possibility of an excavation failure. The County is required to build safety into job 
planning.
2.
County departments are required to develop safety checklists prepared by a competent person 
before starting work to make certain there is adequate information about the jobsite and to ensure 
all needed items are on hand. These checklists should incorporate elements of the relevant OSHA 
standards as well as other information necessary for safe operations. Specific site conditions must 
be taken into account:
a.
Traffic
b.
Nearby structures and their conditions
c.
Soil classification
d.
Surface water,
e.
Ground water
f.
The water table
g.
Overhead and underground utilities
h.
Weather
i.
Previous excavations
3.
Before any excavation begins, Arizona Blue Stake shall determine the estimated location of utility 
installations (e.g., sewer, telephone, fuel, electric, waterlines, or any other underground 
installations) that may be encountered during the excavation. Operators must also ask the utility 
companies or owners to find the exact location of the underground installations. If underground 
installations are exposed, OSHA regulations also require that they be removed, protected or 
properly supported. The appropriate utility company must be contacted for their requirements on 
excavations where excavations are within 20 feet of overhead utilities.
4.  When all the necessary specific information about the job site is assembled,  the amount, kind  
and cost of the safety equipment needed will be determined by the County. A careful inventory of 
the safety items on hand should be made before deciding what additional safety material must be 
acquired. No matter how many trenching, shoring and back filling jobs have been performed in the 
past each job should be approached with the utmost care and preparation.
B.
Before Beginning The Job

Departments are responsible for providing the appropriate personal protective equipment (PPE) to all 
employees. This includes but is not limited to, hardhats, vests, goggles, safety glasses, gloves and 
safety shoes. Workers must also be instructed on removing or neutralizing surface encumbrances 
that may create a hazard. Employees must wear appropriate PPE when working inside excavations.
In addition, no employee should operate equipment without first being properly trained and fully 
alerted to potential hazards. Training site safety and health programs should incorporate effective 
procedures for immediate notification and investigation of accidents.
C.
On-The-Job Evaluation
Before the start of work and as needed throughout the day a competent person must inspect 
excavations. Adjacent areas must also be inspected for possible cave-ins, failures of protective 
systems and equipment, hazardous atmospheres or other hazardous conditions. If any of these 
conditions are encountered employees must be immediately removed from the hazardous area until 
the necessary safety precautions have been taken. Inspections are also required after natural (e.g., 
heavy rains) or man-made events (e.g., blasting) that may increase the potential for hazards.
D.
Exposure To Vehicular Traffic
Employees exposed to vehicular traffic shall be provided with and shall wear, warning vests or other 
suitable garments marked with or made of reflectorized or high- visibility material.
E.
Exposure To Falling Loads
Employees are not permitted underneath loads handled by lifting or digging equipment. Employees 
shall be required to stand away from vehicles being loaded or unloaded to avoid being struck by any 
spillage or falling materials. Operators may remain in the cabs of vehicles being loaded or unloaded 
when the vehicles are equipped in accordance with OSHA Standard 29 CFR 1926.601(b)(6).
Warning systems such as barricades, hand or mechanical signals or stop logs shall be used when 
mobile equipment is operated adjacent to an excavation. Warning systems shall be used when the 
operator does not have a clear and direct view of the edge of the excavation. If possible, the grade 
should be away from the excavation.
III. CAVE-INS AND PROTECTIVE SUPPORT SYSTEMS
A. Support Systems
1.
Excavation workers are exposed to many hazards, but the chief hazard is cave-ins. OSHA requires 
that excavations that are unstable or greater than 5 feet in depth be protected by sloping,      
shoring or benching the sides of the excavation, supporting the sides of the excavation or placing a 
shield between the side of the excavation and the work area.
2.
Designing a protective system can be complex because of the number of factors involved:

Page 5 of 8
Policy Number:
A2234n
Policy Title:
EXCAVATION PROCEDURES
Current Adoption 
Date:
5-20-2015
a.
Soil classification
b.
Depth of cut
c.
Water content of soil
d.
Changes due to weather and climate
e.
Other operations in the vicinity
3.
This standard provides several different methods and approaches for designing protective systems 
that can be used to provide the required level of protection against cave-ins.
B.
Protective Systems Method 1
One method of ensuring the safety of excavation workers is to slope the sides to an angle no greater 
than steeper than one and one-half horizontal to one vertical (34 degrees measured from the 
horizontal). These slopes must be excavated to form configurations that are in accordance with those 
for Type C soil found in the definitions below A slope of this gradation or less is considered safe for 
any type of soil (see Figure 1).
All simple slope excavations 20 feet or less in depth shall have a maximum allowable slope of 
1.5:1.
Figure 1. Excavations Made in Type C Soil
C. Protective Systems Method 2
A second design method, which can be applied for both sloping and shoring, involves using tabulated 
data approved by a registered professional engineer. This data must be in writing and must include 
sufficient explanatory information to enable the user to make a selection. The criteria for determining 
the selection and the limits on the use of the data must be included.
At least one copy of the information, including the identity of the registered professional engineer who 
approved the data, must be kept at the worksite during construction of the protective system.

D. Trench Box And Shield
Employees may use a trench box or shield that is either designed by, or is based on tabulated data 
prepared or approved by a registered professional engineer. OSHA standards permit the use of a 
trench shield (also known as a welder’s hut) as long as the protection it provides is equal to or greater 
than the protection that would be provided by the appropriate shoring system (see Figure 2).
Figure 2. Trench Shields
E. Safety Precautions
1.
The employer is required to provide support systems such as shoring, bracing or under pinning to 
ensure the stability of adjacent structures such as buildings, walls, sidewalks or pavement.
2.
Excavation below the level of the base or footing of any foundation or retaining wall is prohibited 
unless:
a.
A support system such as underpinning is provided
b.
The excavation is in stable rock
c.
A registered professional engineer determines that the structure is sufficiently removed 
from the excavation and that excavation will not pose a hazard to employees.
3.
Excavations under sidewalks and pavement are also prohibited unless an appropriately designed 
support system is provided or another effective method is used.
F. Installation And Removal Of Protective Systems
1.
This standard requires the following procedures for the protection of employees when installing 
support systems:
a.
Securely connect members of support systems
b.
Safely install support systems
c.
Never overload members of support systems
d.
Install other structural members to carry loads imposed on the removal of individual members

Page 7 of 8
Policy Number:
A2234n
Policy Title:
EXCAVATION PROCEDURES
Current Adoption 
Date:

as necessary
2.
In addition, the standard permits excavation of 2 feet or less below the bottom of the members of a 
support or shield system of a trench if both:
a.
The system is designed to resist the forces calculated for the full depth of the trench
b.
There are no indications, while the trench is open, of a possible cave-in below the bottom of 
the support system.
3.
The installation of support systems must be closely coordinated with the excavation of trenches. 
As soon as work is completed, the excavation should be back-filled as the protective system is 
dismantled.
4.
After the excavation has been cleared, workers should slowly remove the protective system from 
the bottom up, taking care to release members slowly.
G. FALLS AND EQUIPMENT
1.
In addition to cave-in hazards and secondary hazards related to cave-ins, there are other hazards 
from which workers must be protected during excavation related work. These hazards include 
exposure to falls, falling loads and mobile equipment. To protect employees from these hazards, 
OSHA requires the employer to take the following precautions:
a.
Keep materials or equipment that may fall or roll into an excavation at least 2 feet from the 
edge of excavations, and/or have retaining devices.
b.
Provide warning systems such as mobile equipment, barricades, hand or mechanical 
signals, or stop logs, to alert operators of the edge of an excavation. If possible, keep the 
grade away from the excavation.
c.
Provide scaling to remove loose rock and soil or install protective barricades and other 
equivalent protection to protect employees against falling rock, soil or other materials.
d.
Prohibit employees from working on faces of sloped or benched excavations at levels
above other employees, unless employees at lower levels are adequately protected from the 
hazard of falling, rolling or sliding materials or equipment.
e.
Prohibit employees from being under loads that are handled by lifting or digging equipment. To 
avoid being struck by any spillage or falling materials, require employees to stand away from 
vehicles being loaded or unloaded. If cabs of vehicles provide adequate protection from falling 
loads during loading and unloading operations, the operators may remain in them.
H. WATER ACCUMULATION
1.
Employees are prohibited from working in excavations where water has accumulated or is 
accumulating unless adequate protection has been taken. If water removal equipment is used to 
control or prevent water from accumulating, it must be monitored to ensure proper use.
2.
OSHA standards also require that diversion ditches, dikes or other suitable means be used to 
prevent surface water from entering an excavation and to provide adequate drainage of the area 
adjacent to the excavation. A competent person must inspect excavations subject to runoffs from 
heavy rains.

I.
HAZARDOUS ATMOSPHERES
Under this standard, a competent person must test excavations greater than 4 feet in depth, as well as 
ones where oxygen deficiency or a hazardous atmosphere exists or could reasonably be expected to 
exist, before an employee enters the excavation. If hazardous conditions exist, controls such as proper 
respiratory protection or ventilation must be provided. Controls used to reduce atmospheric 
contaminants to acceptable levels must be tested regularly.
J.
ACCESS AND EGRESS
Under this standard, the employer must provide safe access and egress for all excavations. According 
to OSHA regulations, when employees are required to be in trench excavations 4-feet deep or more, 
adequate means of exit, such as ladders, steps, ramps or other safe means of egress, must be 
provided and must be within 25 feet of lateral travel. If structural ramps are used as a means of access 
or egress, they must be designed by a competent person if used for employee access or egress, or a 
competent person qualified in structural design if used by vehicles. Also, structural members used for 
ramps or runways must be uniform in thickness and joined in a manner to prevent tripping or 
displacement.

PURPOSE
MARICOPA COUNTY INTERNAL POLICY
The program is intended to comply with Federal Regulations OSHA Standard 29 CFR 1910.134, and 
the Arizona Division of Occupational Safety and Health Standard for Respiratory Protection. This 
program should prevent employee exposure to situations of inadequate oxygen and/or inhalation of 
harmful substances, provide information and guidance on the proper selection and use of the 
respirators that will help safe guard the occupational health of employees at the County and 
supplement “Department Respiratory Protection Written Plans”
II.
APPLICATION
The County Respiratory Protection Program covers all County employees required to work in situations 
where oxygen may be lacking or where potentially harmful dust, fogs, smokes, mists, fumes, gases, 
vapors or sprays may be present including substances that may cause impairment, disease or death.
III. POLICY
A.
Respirators used for protection against airborne contaminants will be selected from those 
approved by the National Institute for Occupational Safety and Health (NIOSH) 42 CFR 84. 
Effective respiratory protection shall be specified and issued for each job by a competent 
individual. Selecting the right respirator requires an assessment of the workplace. All hazards 
and their airborne concentrations must be identified before selecting a respirator. The following 
are the most commonly used respirators:
1.
Filtering Face Piece Respirators or particulate respirators, commonly referred to as 
N95’s: These are the simplest and most common form of respiratory protection. Filtering face 
piece respirators are air-filtering devices that cover the nose and mouth to trap particles, in the 
air before inhalation. These masks must have two straps and are effective only if they fit snugly. 
Masks should not be over-used to the point of clogging.  These filtering respirators must be fit 
tested if the WHA determines they are required..
2.
Half Masks: Air-purifying devices cover the nose, mouth and chin. Half masks have cartridges 
that capture gases and vapors from the air. Each cartridge is made for a specific gas or vapor 
hazard. A pre-filter may be attached to the cartridge to trap dusts, fumes, and mists. Fit testing 
is required for half mask respirators.
3.
Full-Face Masks: Full-face masks are air-purifying respirators like half masks, with the addition 
of a face-piece to protect the eyes. These masks fit snugly around the face with a canister or 
cartridge to capture gas and vapor hazards from the air. Fit testing is required for full-face 
respirators.
4.
Self-Contained Breathing Apparatus (SCBA): SCBA respirators are carried on the users 
back. Clean air flows through a regulator to the mask and the air supply is rated for 30 or 60 
minutes. The actual length of time the SCBA is effective depends on the user’s size, physical 
condition and type of activity being performed. An alarm will warn the user when the air supply 
is low. Fit testing is required for SCBAs.

5.
Negative-Pressure Respirator: A negative-pressure respirator develops a negative  
pressure or "suction" on the inside of the face-piece during inhalation. During exhalation, the 
air pressure in the facemask becomes positive. Half-mask and full-face-piece air purifying 
respirators are negative-pressure respirators, both require fit testing.
6.
Positive-Pressure Respirator: The pressure inside the facemask of a positive-pressure 
respirator is positive during both inhalation and exhalation. It is important that the positive 
pressure within the facemask be maintained during use. If negative-pressure develops, 
contaminants outside the face-piece may be drawn into the wearer's breathing zone. Fit 
testing is required for positive pressure respirators.
B. Program Administration:
Directors shall designate a person, hereafter referred to as the program administrator, to 
administer the Respiratory Protection Program for their Department. The program 
administrator must have sufficient knowledge of respirators and OSHA Standard1910.134 to 
supervise the program. The program administrator shall have the following responsibilities:
1.
Supervises the respirator selection process
2.
Establishes training sessions for employees using respiratory protection equipment
3.
Performs and coordinates fit testing of respiratory equipment
4.
Establishes a continuing program to clean, inspect and replace respiratory equipment
5.
Establishes a procedure to issue and track equipment
6.
Evaluates and continually ensures effective functioning of equipment
7.
Oversees a medical screening program for employees using respiratory equipment
8.
Oversees monitoring schedules for those requiring the use of respiratory equipment to 
determine employee exposures
9.
Performs periodic audits to ensure program effectiveness
C. Respiratory Selection:
1.
The basic purpose of any respirator is to protect the respiratory system from harmful 
airborne physical, chemical and/or biological agents. It provides this protection either by 
removing the contaminant from the air before it is inhaled or by supplying an independent 
source of purified bottled or compressed breathing air. The County must ensure that 
employees are not exposed to airborne contaminants in excess of the OSHA 8-hour 
permissible exposure limit (PEL), a 15-minute short-term exposure limit (STEL), or other 
applicable health standards. Respirators shall be selected and used to reduce employee 
exposures to airborne concentrations of contaminants to levels that are less than the "action 
level", which is generally one-half the PEL. For blends and compounds of chemicals, follow 
the guidelines set forth on the Safety Data Sheet. Choosing the right equipment involves 
several steps:
a.
Choose equipment that is certified for the function
b.
Test the device
c.
Determine the nature and extent of the hazard
2.
Chemical and physical properties of the contaminant, as well as the toxicity and 
concentration of the hazardous material and the amount of oxygen present, must be 
considered in selecting the proper respirators. The nature and extent of the hazard, work 
rate, area to be covered, mobility, work requirements and conditions, as well as the 
limitations and characteristics of the available respirators also are selection factors.

Policy Number:
A2234o
Policy Title:
RESPIRATORY PROTECTION PROGRAM
Current Adoption 
Date:
5-20-2015
3.
The removal of contaminants through engineering controls shall be the primary method for 
controlling employee exposures to airborne contaminants. OSHA has identified the following 
circumstances acceptable for primary reliance on respirators:
a.
When engineering controls are not feasible
b.
During the time necessary to install engineering controls
c.
Where engineering controls do not sufficiently reduce exposure
d.
During emergencies, lifesaving, recovery operations and field operations where there is 
a lack of utilities for implementing engineering controls
e.
Operations requiring added protection where there is a failure of normal controls
f.
Entries into unknown or potentially hazardous atmospheres
D. Exposure Assessment
The concentration of airborne contaminants to which employees are exposed must be 
periodically determined. Records of exposure monitoring must be kept for the duration of 
employment plus 30 years. Records must also be kept on the type of respirator issued to each 
employee, including the date of issue and a list of repairs.
E.
Program Evaluation
1.
Respirators shall be inspected periodically by the department's program administrator to 
ensure they are effective. Periodic program evaluation of respirator usage shall include the 
following:
a.
Determination that the proper respirators are being used
b.
Determination that the respirator users are properly trained
c.
Determination that respirators are being properly worn, cleaned and maintained
d.
Determination that a medical evaluation was performed on the user prior to the issuing 
of the respirator
2.
An effective program evaluation shall include consultation with the users regarding the following:
a.
Comfort
b.
Resistance to breathing
c.
Protection confidence
d.
Fatigue
e.
Interference
f.
Restriction of movement
F.
Medical Surveillance
1.
Using a respirator can impose physiological stress on the user. Air-purifying respirators, for 
example, may make breathing more difficult because the filter or cartridge can increase 
resistance to the flow of air. If an employee has a lung or heart condition, wearing a 
respirator may present a health risk.
2.
As required under the OSHA Standard 29 CFR1910.134(e), no employee shall be assigned 
to tasks requiring respiratory protection unless it has been determined that they are 
physically able to perform the work and use the equipment. A qualified physician shall 
determine whether or not the employee will be able to function normally wearing a respirator. 
New employees shall be examined prior to employment. Medical testing is required on initial 
assignment to wear a respirator or if the exposure to the materials being handled requires a

physical, for example in handling highly toxic chemicals or carcinogens.  In accordance with 29 
CFR 1910.134(e)(7) — Respiratory Protection: “Additional medical evaluations are required 
under certain circumstances, e.g.:
a.
Employee reports medical signs or symptoms related to ability to use respirator
b.
Physician or Licensed Health Care Provider, program administrator, or supervisor 
recommends reevaluation
c.
Information from the respirator program, including observations made during fit testing 
and program evaluation, indicates a need; or change occurs in workplace conditions that 
may substantially increase the physiological burden on an employee.
3.
A statement by the examining physician that the employee is capable of wearing a respirator 
shall be maintained for each user for the duration of their employment.
4.
A physician or Licensed Health Care Provider are to perform medical evaluations using a 
medical questionnaire or an initial medical examination that obtains the same information as  
the medical questionnaire. Employees who provide a positive response to the medical 
questionnaire or do not satisfactorily pass administered pulmonary function testing will be sent 
for a follow-up medical examination. The follow-up medical examination shall include any 
medical tests, consultations or diagnostic procedures that the Physician or Other Licensed 
Health Care Professional deems necessary to make a final determination. Medical evaluations 
shall include the completion of a medical questionnaire in accordance with OSHA Standard 29 
CFR 1910.134, Part A of Appendix C.
G. Training Program
1.
Proper use of respirators depends on the program administrator, supervisors and 
employees being thoroughly trained in their selection, use and maintenance. The content of 
a training program can vary depending on the work place hazards and employee activities. 
Training for the program administrator, supervisors and employees shall include:
a.
An opportunity for the user to handle the respirator
b.
Testing of the face piece to ensure proper fit
c.
Wearing the respirator in normal air for an appropriate familiarity period
d.
Wearing the respirator in a test atmosphere
2.
A training session requiring employee attendance shall be conducted by a properly trained 
person to inform employees about the limitations, use and maintenance of respiratory 
protection equipment. Every respirator wearer shall receive fitting instructions including 
demonstrations and practice in how the respirator should work, how to adjust it and how to 
determine if it fits properly. A thorough training program should also include the following:
a.
Reasons for needing respiratory protection and how improper fit, usage or maintenance 
can compromise the protective effect of the respirator
b.
What the limitation and capacities of the respirator are
c.
How to use the respirator effectively in emergency situations, including if the respirator 
malfunctions
d.
How to inspect, put on and remove, use and check the seals of the respirator
e.
Proper maintenance and storage of the respirator
f.
Proper respirator fit
g.
Appropriate respirator selection for the hazards to which the employee is exposed
h.
Proper respirator use under the work place conditions the employee encounters
i.
How to recognize medical signs and symptoms that may limit or prevent the effective

use of respirators
j.
The general requirements of OSHA Standard 29 CFR 1910.134
3.
Each employee shall receive initial and annual respiratory protection training. The 
department program administrator will input the training record into Pathlore and keep the 
form on file.
H.
Respirator Fit-Testing
1.
Each employee who must use a tight-fitting (negative pressure) respirator shall be fit-tested 
prior to initial use of the respirator, whenever a different respirator face piece is used and 
annually thereafter. Each employee will be allowed to choose the most comfortable 
respirator from a selection of sizes and manufacturers.
2.
Tight-fitting respirators shall not be worn when conditions prevent a good seal. If the 
respirator is not tight fitting, there may be physical obstacles such as a beard, stubble, 
sideburns, a skull caps that protrudes under the face piece or eyeglasses, that may prevent 
a good fit. Employees who are required to wear respiratory protection cannot         
have facial hair that would prohibit a proper seal (See HR for ADA-related questions).
3.   Contact lenses must not be worn with a respirator in contaminated atmospheres if 
they increase the likelihood of an injury. If any employee needs to wear corrective lenses 
with full-face-piece equipment, the lenses shall be fitted by qualified individuals and provide 
good vision, comfort and a gas-tight seal. Facial scars, the absence of dentures or changes 
in facial features due to weight loss or gain can also affect the fit of a face-piece.
I.
Negative And Positive Pressure Tests
1.
In order to ensure proper fit, a negative and positive pressure test shall be performed each 
time an employee wears a respirator. These tests shall be administered using accepted 
protocols and procedures listed in OSHA Standard 29 CFR 1910.134 Appendix A.
2.
Negative Pressure Test:
a.
Close off the inlet of the canisters, cartridges or filters by covering them with the palms 
of the hands.
b.
Replace the seal(s) or squeeze the breathing tube so that it does not allow air to pass.
c.
Inhale gently so that the face-piece collapses slightly.
d.
Hold breath for 5 seconds.
e.
If the face-piece remains slightly collapsed and no inward leakage is apparent, the 
respirator passes the test.
3.
Positive Pressure Test: This test is similar to the negative-pressure test and consists of the 
following steps:
a.
Close off the exhalation valve or air outlet
b.
Exhale, breathe gently
c.
The fit is considered satisfactory if slight positive pressure can be built up for 5 seconds 
inside the face-piece without any evidence of outward leakage.
J.
Procedures For IDLH Atmospheres
1.
In situations in which employees perform work in an atmosphere with immediately dangerous to 
life and health (IDLH) conditions the following procedures apply:

K.
Respirator Inspection And Maintenance
1.
Respirators, other than N95’s, must be inspected during cleaning. Each individual is 
responsible for cleaning, inspecting and storing their respirator after each use or as needed. 
Respirators used only for emergency escape or rescue purposes must be inspected after 
each use and at least monthly between uses.
2.
A record is to be kept with the department supervisor, of inspection dates and findings for 
emergency use respirators.
3.
Employees using air-purifying respirators shall change the filter elements when they detect 
increased resistance to breathing, taste or smell of the contaminant, an increase in the 
temperature of the inhaled air or increased eye or mucous membrane irritation, whichever 
occurs first. When respirators are used for emergency response the filter elements or 
cartridges shall be changed after each use.
L.
Respirator Cleaning And Storage
Each employee must be trained on respirator cleaning procedures and issued a clean, 
disinfected respirator in accordance with the NIOSH suggested procedures. Each employee is 
responsible for ensuring their respirator is cleaned and disinfected as needed.
M. Self-Contained Breathing Apparatus – Additional Instructions
1.
The program administrator shall inspect SCBA equipment monthly. Air cylinders must be 
fully charged according to the manufacturer’s instructions. Regulator and warning devices 
must be inspected to ensure they are functioning properly. A record shall be kept of 
inspection dates and findings.

overemphasized. Detergents or disinfectants that dry on face pieces may result in 
dermatitis. In addition, some disinfectants may cause deterioration of rubber or corrosion 
of metal parts if not completely removed.
6.
Components should be hand-dried with a clean lint-free cloth or air-dried.
7.
Reassemble face piece, replacing filters, cartridges and canisters where necessary.
8.
Test the respirator to ensure that all components work properly.
P.
Information for Employees Using Respirators Not Required Under the Standard
Respirators are an effective method of protection against designated hazards when properly 
selected and worn. Respirator use is encouraged, even when exposures are below the exposure 
limit, to provide an additional level of comfort and protection for workers. However, if a respirator 
is used improperly or not kept clean, the respirator itself can become a hazard to the worker.
Sometimes workers may wear respirators to avoid exposures to hazards, even if the amount of 
hazardous substance does not exceed the limits set by OSHA standards.

Assignment of responsibility for the program
b.
A permit system
c.
Provision of the necessary safety equipment
d.
Provision of the personnel necessary to implement the safety regulations
2.
In order to prevent cutting and welding losses, a responsible person should be appointed 
to closely supervise the use of all portable cutting, welding and other hot work equipment. 
Employees and outside contractors must secure a written permit from this supervisor 
before beginning any hot work.
3.
A cutting, welding or hot work permit should be filled out each time hot work is conducted.
C.
Hot Work Permit
A competent individual such as a welding supervisor, maintenance foreman, plant engineer or 
master mechanic supervises the Hot Work Permit Program. The competent individual should 
examine the work location to determine what precautions must be taken. The competent 
individual issues the permit that must be posted at the job site.  No work shall be allowed 
without a properly issued permit at the job site. If work at the location continues for more than 
one shift, a new permit will be issued for each shift. If the working conditions cannot be made 
safe, the competent individual shall not issue the permit.

INJURY AND ILLNESS PREVENTION PLAN: 
WELDING, CUTTING & HOT WORK
Current Adoption 
Date:
5-20-2015
Welders and other personnel utilizing hot work equipment shall be instructed to take all 
necessary precautions. A list of these precautions shall be posted in the maintenance shop, on 
the equipment and on the permit. These precautions should include the following:
1.
Perform hot work in a properly arranged maintenance shop except when the job cannot be 
moved to a shop.
2.
Thoroughly check valves, regulators, hoses and torches. Only use equipment that is in 
good condition.
3.
Refrain from use of portable welding, cutting or other hot work equipment in a building 
where sprinklers are out of service.
4.
Move combustibles at least 35 feet from hot work operations. If combustibles cannot be 
moved, they must be protected by metal guards, flameproof curtains or covers rather than 
ordinary tarpaulins.
5.
Prohibit hot work in or on vessels containing flammable or combustible materials, including 
residues, until they have been completely cleaned and purged.
6.
Check the atmosphere for combustible gases or vapors using reliable combustible gas 
detection equipment. If there is a chance of a gas or vapor release during hot work 
operations, continuous-duty portable combustible-gas detectors should be used to monitor 
the area.
7.
Prohibit hot work until surrounding floors have been swept clean or, if combustibles are 
present, wet down.
8.
Prohibit hot work until all wall and floor openings within 35 feet of the operations have been 
tightly covered or otherwise protected with metal guards or flameproof tarpaulins.
9.
Prohibit hot work until responsible persons have been assigned to watch for dangerous 
sparks in the area and on floors above and below.
10. Secure gas cutting and welding cylinders so they will not be upset or damaged.
11. Carefully connect the ground clamp when using electrical arc-welding equipment. Since an 
improperly made ground can be a source of ignition, the ground clamp should be 
connected as close to the work as possible so that it may be easily observed.
12. Arrange for a patrol of the area, including floors above and below, during any break in the 
work such as lunch or rest periods and for at least half an hour after the work has been 
completed. If the hot work ends near the time of a shift change, arrangements should be 
made for the patrols to continue into the next shift.
E.
Training And Qualification
Employees that operate any County welding apparatus must be trained and qualified prior to 
job assignment. The County offers a welding qualification program billed to the departments. 
The program covers OSHA required welding, cutting, hot work safety training, and welding 
certifications for those whose final test pass the x-ray certification test.

recommended for this.
3.
Unless cylinders are secured on a special truck regulators shall be removed and valve- 
protection caps, when provided, shall be put in place before cylinders are moved.
4.
Cylinders not having fixed hand wheels shall have keys, handles or nonadjustable 
wrenches on valve stems while these cylinders are in service. In multiple cylinder 
installations only one key or handle is required for each manifold. Cylinder valves shall be 
closed before moving cylinders, and cylinder valves shall be closed when work is finished.
5.
Cylinders shall be kept far enough away from the actual welding or cutting operation so  
that sparks, hot slag or flame will not reach them, or fire-resistant shields shall be provided.
6.
Cylinders shall not be placed where they might become part of an electric circuit. Contacts 
with third rails, wires, etc., shall be avoided. Cylinders shall be kept away from radiators, 
piping systems, layout tables, etc., that may be used for grounding electric circuits such as for 
arc welding machines. Tapping an electrode against a cylinder to strike an arc shall be 
prohibited. Cylinders shall never be used as rollers or supports, whether full or empty.
7.
No person, other than the gas supplier, shall attempt to mix gases in a cylinder. No one, 
except the owner of the cylinder or person authorized by him, shall refill a cylinder and no 
one shall tamper with safety devices in cylinders or valves.
8.
Unless connected to a manifold, oxygen from a cylinder shall not be used without first 
attaching an oxygen regulator to the cylinder valve. Before connecting the regulator to the 
cylinder valve, the valve shall be opened slightly for an instant and then closed. Always 
stand to one side of the outlet when opening the cylinder valve. If valves cannot be opened 
by hand, the supplier shall be notified. A hammer or wrench shall not be used to open 
cylinder valves.
9.
Cylinder valves shall not be tampered with nor should any attempt be made to repair them. 
If trouble is experienced, the supplier should be sent a report promptly indicating the 
character of the trouble and the cylinder's serial number.
10. Fuel-gas cylinders shall be placed with valve end up whenever they are in use. Liquefied 
gases shall be stored and shipped with the valve end up. Cylinders shall be handled 
carefully. Rough handling, knocks, or falls are liable to damage the cylinder, valve or safety 
devices and cause leakage.
K.
Regulator Connection And Removal
1.
Before connecting a regulator to a cylinder valve, the valve shall be opened slightly and 
closed immediately. The valve shall be opened while standing to one side of the outlet; 
never in front of it. Never crack a fuel-gas cylinder valve near other welding work or near 
sparks, flame or other possible sources of ignition. Before a regulator is removed from a 
cylinder valve, the cylinder valve shall be closed and the gas released from the regulator.
2.
Nothing that may damage the safety device or interfere with the quick closing of the valve 
shall be placed on top of an acetylene cylinder when in use.
3.
If cylinders are found to have leaky valves or fittings which cannot be stopped by closing of 
the valve, the cylinders shall be taken outdoors away from sources of ignition and slowly 
emptied.
4.
A warning not to approach cylinders with a lighted cigarette or other sources of ignition 
should be placed near all cylinders. Cylinders that have leaking fuse plugs or other leaking 
safety devices should be tagged; the supplier should be promptly notified and their 
instructions followed as to the cylinders’ return.

Fall Protection Procedures:
1.
Employees shall use a fixed rail protection system whenever possible.
2.
Employees shall inspect the fall protection system prior to each use.
3.
When climbing a ladder three points of contact must be maintained: two hands and a foot or 
two feet and a hand.
4.
Employee shall not carry bulky or heavy objects while climbing.
5.
Employees shall use a towline or tool belt to carry objects.
6.
Employees who perform job duties in aerial/scissor lifts shall use a full body harness with the 
appropriate lanyard.
C.
Employee Training
The County shall provide a training program for each employee exposed to fall hazards. The 
program shall enable each employee to recognize the hazards of falling and shall train each 
employee in the procedures to be followed in order to minimize these hazards. All training shall 
be maintained in the County training database, as appropriate.
D.
Inspection Of Job Sites
While ADOSH standards specifically exclude inspections of roofs from fall protection standards, 
inspectors should receive awareness level fall protection training. This training shall include 
training in hazard identification, environmental factors, engineering controls and types of fall 
protection systems.
E.
Controlled Access Zones
1.
Workers shall be protected through limited access to high hazard locations. Before any fall 
protection systems are used as part of the job site work plan, a Controlled Access Zone 
(CAZ) shall be clearly defined by a competent person as an area where a recognized hazard 
exists. The competent person shall demarcate the CAZ through signs, wires, tapes, ropes or 
chains.
2.
The following steps shall be taken to ensure that the CAZ is clearly marked or controlled by a 
competent person:
a.
All access to the CAZ must be restricted to authorized entrants.
b.
All workers who are permitted in the CAZ shall be listed in the appropriate sections of the 
job site work plan.
c.
A competent person shall ensure that all protective elements of the CAZ are implemented 
prior to the beginning of work.
F.
Enforcement
Constant awareness of fall hazards and compliance with all safety rules are considered 
conditions of employment. Job site supervisors reserve the right to issue corrective actions for 
failure to follow safety rules.

G. Fall Protection Response
1.
Per OSHA 1926.502(d)(20) - In the event of a fall where an employee is suspended by a fall 
arrest system, prompt rescue is required. On-site employees shall:
a.
Call 911 to summon first responders.
b.
Remain in verbal and/or physical contact with the suspended employee at all times.
c.
Encourage the suspended employee to pump their legs to activate muscles to reduce 
venous pooling.
d.
Keep in contact with first responders to orient them to the rescue site.
e.
Clear areas where the first responders will need access to the incident site.
2.
When applicable, an employee may rely on a self-rescue device after an arrested fall and not 
be required to use additional fall protection.
a.
An employee using a rope ladder, such as a Jacob’s ladder, does not require additional 
fall protection.
b.
An employee using a descent control device or a ladder to effect self-rescue, may not be 
able to remain connected to the original fall protection due to restriction in downward 
movement.
3.
An employee using an ascender to return to a protected station at height must remain 
connected to the original fall protection, such as a lanyard, because the employee would not 
have their upward movement restricted by its presence. Once ascension is complete, 
however, it is critical that the employee return to the ground as soon as safely possible 
because the employee’s fall protection equipment is no longer acceptable for use as fall 
protection.
4.
Though the word “prompt” is not defined by OSHA its use still requires that rescues be 
performed quickly so as to prevent serious injury to the employee. The effects of suspension 
trauma can occur in less than 30 minutes and can be fatal.
5.
Please note that OSHA 1926.502 does not require the preparation of a written rescue plan or 
the holding of a preplanning event.
H.
Incident Investigations
All incidents that result in injury to workers, regardless of their nature, shall be investigated by the 
job-site supervisor and reported to Risk Management. The supervisor shall also complete an 
online claim form as soon as possible. In the event of an employee fall, this plan shall be 
reviewed to determine if additional practices, procedures or training need to be implemented to 
prevent similar incidents from occurring. (See County Policy A2218: Reporting of Industry Injury  
and Illness).

IV. HAND TOOL SAFETY RULES
A.
Most incidents with hand tools are caused by failure to observe one of the 
following rules:
1.
Select the right tool for the job.
2.
Keep tools in good condition.
3.
Use tools in a safe manner.
4.
Keep tools in a safe place at all times.
B.
Accidents can be prevented by adopting a hand tool safety management strategy which 
includes the following:
1.
Training all workers in the proper use and care of hand tools.
2.
Routinely inspecting all tools.
C.
Training:
1.
Supervisors should train workers in the proper use and care of tools. This can be 
incorporated into tailgate safety meetings. Proper use of the correct tool for each job 
should be discussed. Also, the proper care, inspection, and maintenance of the tools 
should be explained, including which parts are most easily broken, how and when to 
lubricate and how to store the tools.
2.
The safe use of the tools should be demonstrated, and the consequences of unsafe 
use discussed. Emphasis should be placed on keeping tools in a safe place when not 
in use. Tools left in unsafe places can get lost; fall on workers or trip workers.
D.
Inspection:
1.
The primary function of regular tool inspections is to ensure that there are enough safe 
tools on hand to do the job. Defective tools must be tagged and then either repaired or 
replaced.
2.
All hand tools must be inspected on a regular basis, including personal tools. Defective 
personal tools should not be used.
3.
The supervisor is responsible for ensuring that the tools used on the job are in good 
condition and that all tools necessary to do the job safely are available on the site. The 
worker’s prime responsibility is to use tools in such a way that no one gets hurt. This 
includes knowing the rules governing the use of tools, following them and exercising 
common sense.
V.
POWERTOOLS
A.
Workers can experience electric shock, particles in the eyes, burns, cuts and strains while 
using power tools. Most hazards can be eliminated by:
1.
Keeping power lines and hoses out of passageways where they can present a fall 
hazard. Lines and hoses deteriorate quickly if materials are dropped or driven over.
2.
Keeping lines and hoses away from heat and sharp edges and out of oil and 
chemicals.
3.
Disconnecting tools from power sources before making repairs or adjustments. Keys

Page 4 of 5
Policy Number:
A2234t
Policy Title:
MACHINE SAFE GUARDING & TOOL 
SAFETY
Current Adoption 
Date:

must be removed and guards replaced before reconnecting tools to power sources.
4.
Before turning on tools, the area should be checked and potential hazards identified 
and corrected.
5.
When working outside or when plugging in to a non-ground fault circuit interrupter 
(GFCI) outlet, employees shall use a portable GFCI cord to prevent shock.
B.
Electric Power Tools:
1.
Observing safe work practices can prevent electrocution, burns and shocks. Only 
properly grounded or double insulated tools should be used. Additionally, 110 volt, 
single phase 15-20 amp outlets that are not part of a permanent wiring system are 
required to have GFCI or to be incorporated into an assured equipment grounding 
conductor program.
2.
Before each use, electric tools should be inspected for proper grounding, frayed or 
broken wires and cracked plugs. All extension cords should be grounded, and ground 
prongs should never be cut off. Electric tools should not be used when the operator is 
wet, standing on wet ground or flooring or in explosive atmospheres. Care should be 
exercised to avoid cutting through the power supply.
C.
Pneumatic Power Tool:
1.
Pneumatic power tools present special hazards because their pressurized hoses can  
be cut, disconnected or punctured by a careless operator, another worker, falling debris 
or vehicles and equipment running over them. Deterioration from contact with heat or 
chemical agents or poorly fastened couplings can also cause an air hose to whip. Only 
approved couplings for the type of hose and working pressure should be used and only 
with the appropriate coupling safety devices. Air hoses should have a safety device at 
the source of the air supply to lower the air pressure in case of hose failure.
2.
Hand-held air hammers can become lethal weapons when misused. A tool that is not 
secured properly can fly out of its retainer with tremendous force and cause serious 
injury to the operator or to other workers. Pneumatic tools are equipped with automatic 
shut-off switches should never be tied down in the "on" position. All other tool safety 
devices must be engaged properly before the tool is used. To avoid injury from free- 
flying tools, do not squeeze the trigger until the tool is on the work. Air compressors can 
injure or kill when misused. At the source of supply or branch line, there shall be a 
pressure-reducing valve to reduce air pressure in case of hose failure. When attaching 
air hoses all couplings shall be secured with a safety clip or wire. All pneumatic tools 
shall be secured to the hose or whip by positive means to prevent the tool from 
becoming accidentally disconnected.
3.
Before each use air hoses will be examined for deterioration and for positive clamping 
of fittings. Before changing air valves will be shut off from source of supply. Under no 
conditions shall a hose be kinked to stop airflow. Air hoses shall be kept out of aisle 
ways or areas where they can be damaged by traffic or falling materials.
4.
When using compressed air, personal protective safety equipment is needed. It is the 
employer's responsibility to see that the employees wear all necessary safety 
equipment.
5.
Cleaning clothes with compressed air is extremely dangerous and shall not be permitted. 
Workers shall be informed that pointing or touching the compressed air hose opening to 
the body can damage an ear drum, blow out an eye, inflate a part of the body, or inject air 
bubbles into the blood stream which can be fatal.

Gasoline Power Tools:
1.
Gasoline-powered tools present hazards associated with the use of flammable liquids 
and dangers from toxic fumes. Gasoline should never be poured on hot surfaces. It 
should be kept away from flames and lit cigarettes. One should not fuel an engine while 
it is operating. To avoid the deadly build-up of toxic fumes, adequate ventilation should 
be provided when using gasoline-powered tools in enclosed spaces.

APPENDIX A
INTERPRETING AN OSHA 300A SUMMARY LOG.
The OSHA 300A Summary (example below) is used by OSHA to obtain a short summary of the safety record 
that a company experienced the previous year. The company’s OSHA rate can be calculated from this 
information:
A. Take the number of injuries
B. Multiply this number by 200,000
C. Then divide the result by the total number of hours worked.
Or:
Injuries X 200,000
= OSHA RATE;
Example: 30 injuries X 200,000
= 2.00 
Total Hours
2,500,000 hours
By using the company’s classification, you can compare their rates to others in the same classification (SIC or 
NAICS) by looking at the information available from the Bureau of Labor Statistics (BLS):  
http://www.bls.gov/iif/oshwc/osh/os/ostb2071.pdf.
If a company has a rate higher than their industry average. they are experiencing more injuries than most others in 
their industry. If their rate is lower than their industry average, they are experiencing fewer injuries than most 
others in their industry.

PURPOSE
A Workplace Hazard Assessment (WHA) must be conducted to establish a safe working 
environment. Departments are required to identify potential hazards, establish preventative 
measures and provide necessary training.
II.
PROCEDURE
A. Responsibilities
1. Supervisors will ensure the provisions of this plan are followed.
2. Employees will be trained and assist in WHAs.
3. Risk Management will provide guidance to supervisors on priority of WHA completion 
and will help in the analysis.
B. Prepare To Conduct The WHA
1. Supervisors and employees must identify jobs for the WHA review. Supervisors are 
responsible for assigning at least one employee with particular expertise regarding the job 
under review to the WHA.
2. Determine which jobs are going to have a WHA through employee interviews, a review 
of past accidents and listing and prioritizing hazardous jobs and functions. WHAs can 
be prioritized by using the matrix found at the end of this policy.
C. Conduct WHA
1.
Every job will be rated by its likelihood of occurring and its severity. The 
Workplace Hazard Assessment for this Can be obtained from Risk Management
2.
To conduct a WHA:
a. Review the job with the team and/or watch an employee perform the job, list each 
task/step as the employee makes it. Record enough information to describe each 
job action without being overly detailed.
b. Obtain input from other workers who have performed the same job.
c. Review the job tasks/steps with employees to make sure none have been 
omitted. Include employees in all phases of the analysis, from reviewing the job 
tasks/steps and procedures to discussing uncontrolled hazards and potential 
consequences of any those hazards.

work practices.
3.
Personal Protective Equipment (PPE) includes respirators, hearing protection, 
protective clothing, safety glasses and hard hats.
F. If the WHA shows a high hazard rating on the matrix, a Job Safety Analysis must be 
performed.
1.
Nearly every job can be broken down into job tasks/steps. The Job Safety 
Analysis Form for this review is found on the Risk Management website:  
https://mymc.maricopa.gov/350/Job-Safety-Analysis-Library
2.
To conduct a JSA:
a.
Review the job with the team and/or watch an employee perform the job, list each 
task/step as the employee makes it. Record enough information to describe each 
job action without being overly detailed.
b.
Obtain input from other workers who have performed the same job.
c.
Review the job tasks/steps with employees to make sure none have been 
omitted. Include employees in all phases of the analysis, from reviewing the job 
tasks/steps and procedures to discussing uncontrolled hazards and 
recommended solutions.
III.
TRAINING
A.
Supervisors are responsible to provide and record training for each employee on 
WHAs. Each employee shall be trained to know the following:
1.
How to follow the WHA procedures
2.
Where the WHA for the task is located
3.
Implement preventative measures prescribed by WHA
4.
Recognize hazardous conditions
5.
Understand safe work procedures
B.
Employees must be able to demonstrate an understanding of the training before 
performing work requiring the use of WHAs.
C.
Retraining should occur when the supervisor has reason to believe one or all of the 
following:
1.
An individual, who has already been trained, demonstrates a lack of skill 
or understanding of WHAs
2.
Changes occur in the work tasks/steps that would render previous training obsolete
3.
New hazards are discovered
IV.
WHA M AINTENANCE
B.
Supervisors are responsible to submit an electronic copy of the WHA to the Risk 
Management Safety Division.
C.
Departments need to review and update their WHAs whenever there are changes to 
the job, task, equipment or operation.

Page 4 of 6
Policy Number:
A2234v
Policy Title:
WORKPLACE HAZARD ASSESSMENT
Current Adoption 
Date:

D.
When conducting an incident investigation, use the WHA to determine whether 
changes are needed or if the employee failed to follow job procedures:
1.
Step 1 – Select Job to Analyze
A WHA should be done first for jobs known to have the highest injury rate and next 
for jobs with extreme hazardous elements, etc. see hazard matrix. A WHA should 
be completed for all jobs that have the potential for injury, equipment damage or 
community impact such as biohazards, fires or floods.
2.
Step 2 – Involve the Employee or a Team
Let the employee who is performing the job know that a WHA is being conducted 
on the job itself, and not on the employee. Involve the employee throughout the 
analysis by reviewing the tasks/steps, discussing potential hazards and 
recommending solutions. When a WHA is going to be conducted for a tasks/steps 
that involves many employees, it is best to form a team to address the potential 
issues.
3.
Step 3 – Complete the Job Safety Analysis
If the job is repetitive, do each part as the worker cycles through the tasks/steps. If 
the job is not repetitive it may be helpful to video the job and review the video while 
doing the analysis.
a.
First look at general conditions in the area for hazards such as inadequate 
lighting, noise, tripping hazards, forklift traffic, etc. While these conditions may 
not be a direct element of the job, they may create a hazard during some 
particular task/step in the job. For example, a tripping hazard is not part of a job 
function but may be an incidental hazard. Make notes about problems identified 
so that they can be reported and corrected as soon as possible.
b.
Most jobs can be broken down into tasks/steps. List each task/step in order in the 
first column of the form as you watch the employee do the job. Be sure to record 
enough information to describe the task/step. However, only break the job down 
into the number of tasks/steps that are useful for identifying hazards and training 
employees. For example, “go get blank stock and return to machine” is better  
than three separate steps of “go,” “get” and “return”. Review the tasks/steps with 
the employee. Look for variations in the job or infrequent tasks/steps.
c.
Look for hazards or potential hazards and list them in the second column 
opposite the task/step. Assume that no personal protective equipment is being 
worn – even if the worker is wearing it at the time. Keep in mind, it is likely that 
many tasks will not have hazards, and some tasks may have several hazards 
requiring additional observation.
d.
For each hazard identified write down solutions in the third column opposite the 
hazard. Indicate if no solution is feasible.
4.
Step 4 - Make Changes
Use the WHA to initiate the physical changes that need to be made to the workplace, 
tools, equipment, etc. or to initiate procedure changes to the job. New job procedure 
should be written down. The WHA should warn of potential hazards. Employees 
must be trained if any changes are made. Review the WHA more frequently than the 
five-year cycle if additional hazards are identified, new equipment is utilized or if 
there has been an injury.

I.
PURPOSE
A.
County employees are required to wear hearing protection if they are exposed to noise levels 
at or above 85 decibels. If an employee has been determined to be an “affected” employee, 
for the purposes of this policy, they will wear hearing protection whenever in an established 
hearing protection required area or when performing identified job functions.
B.
Employees may be designated as “affected” if the measured sound levels have a time- 
weighted average of 85 decibels for an eight-hour exposure.
C.
All affected employees shall receive audiometric testing and training in hearing conservation 
in accordance with OSHA Standard 29 CFR 1910.95. Hearing protection shall be evaluated 
and selected by a knowledgeable individual and shall meet all design criteria established by 
ANSI.
D.
Monitoring shall be repeated at appropriate intervals to provide reasonable assurance that 
affected employees are included in the Hearing Conservation Program by the department’s 
designee and Risk Management Safety Division.
II.
POLICY
A.
Testing Procedures
When information indicates that an employee's exposure makes them an affected employee, 
they shall be included in the County’s Hearing Conservation Program.
B.
Sampling
1.
The sampling strategy shall be designed to identify affected employees.
2.
Where circumstances such as high worker mobility, significant variations in sound level  
or a significant component of impulse noise make area monitoring inappropriate, the 
County shall use representative personal sampling to comply with the monitoring 
requirements of this policy unless the County can show that area sampling produces 
equivalent results. All continuous, intermittent and impulsive sound levels from 0 decibels 
to 130 decibels shall be integrated into the noise measurements.
C.
Instrumentation
Instruments used to measure employee noise exposure shall be calibrated. Monitoring shall 
be repeated whenever a change in production, process, equipment or controls increases 
noise exposures to the extent that additional employees may be exposed at or above the 
action level or to the extent that the attenuation provided by hearing protectors is not 
adequate to meet the protection requirements.
D.
Employee Notification

Page 2 of 5
Policy Number:
A2234w
Policy Title:
HEARING CONSERVATION PROGRAM
Current Adoption 
Date:
5-20-2015
The County shall notify each employee of the results of the monitoring and include those 
employees in the program when monitoring shows that they are exposed at or above an 8 
hour time weighted average of 85 decibels.
E.
Observation of Monitoring
The County shall provide affected employees or their representatives with an opportunity to 
observe any noise measurements conducted pursuant to this policy.
F.
Audiometric Testing Program
The County shall establish and maintain an audiometric testing program by making 
audiometric testing available to all affected employees.
G. Baseline Audiogram
1.
New hires that have job descriptions identifying them as affected shall receive a baseline 
audiogram prior to permanent assignment with the County and shall be included in the 
annual audiogram requirement.
2.
Testing to establish a baseline audiogram shall be preceded by at least 14 hours without 
exposure to work place noise. Hearing protectors may be used as a substitute for the 
requirement that baseline audiograms be preceded by 14 hours without exposure to work 
place noise.
3.
The County shall notify employees of the need to avoid high levels of non-occupational 
noise exposure during the 14–hour period immediately preceding the audiometric 
examination.
H.
Annual Audiogram
At least annually after obtaining the baseline audiogram, the County shall obtain a new 
audiogram for each affected employee.
I.
Evaluation of Audiogram
1.
Performance, evaluation and interpretation of employee audiograms shall be performed 
by a qualified industrial audiologist. Each employee's annual audiogram shall be 
compared to that employee's baseline audiogram to determine if the audiogram is valid 
and if a standard threshold shift has occurred.
2.
If the annual audiogram shows that an employee has experienced a standard threshold 
shift, the employee’s manager will be notified and the employee will be scheduled for a 
retest that will be performed within 30 days of the initial audiogram. The audiologist, 
otolaryngologist or physician shall review these audiograms and shall determine whether 
there is a need for further evaluation.
3.
The County shall provide to the person performing the evaluation the following information:
a. A copy of the County's written Hearing Conservation Policy
b. The baseline audiogram and most recent audiogram of the employee being evaluated
J.
Follow-Up Procedures

Page 3 of 5
Policy Number:
A2234w
Policy Title:
HEARING CONSERVATION PROGRAM
Current Adoption 
Date:
5-20-2015
1.
If a comparison of the annual audiogram to the baseline audiogram indicates that a 
standard threshold shift has occurred, the employee shall be informed of this fact in 
writing within 21 days of the determination.
2.
Unless an audiologist, otolaryngologist or physician determines that the standard threshold 
shift is not work related or aggravated by occupational noise exposure, the County shall 
ensure that the following steps are taken when a standard threshold shift occurs:
a. Employees not using hearing protectors shall be fitted with hearing protectors, trained in 
their use and care and required to use them.
b. Employees already using hearing protectors shall be refitted and retrained in the use of 
hearing protectors and provided with hearing protectors offering greater attenuation if 
necessary.
3.
The employee will be referred to a clinic for an audiological evaluation or anatomical 
examination, as appropriate, if additional testing is necessary or if the County suspects that 
a medical pathology of the ear is caused or aggravated by wearing hearing protectors.
4.
The employee is informed of the need for an ontological examination if a medical pathology 
of the ear that is unrelated to the use of hearing protectors is suspected.
5.
If subsequent audiometric testing of an employee whose exposure to noise is less than an 
8–hour time-weighted average of 85 decibels indicates that a standard threshold shift is not 
persistent, the County will do both of the following:
a.
Inform the employee of the new audiometric interpretation
b.
Discontinue the required use of hearing protectors for that employee
K.
Revised Baseline
An annual audiogram may be substituted for the baseline audiogram when, in the judgment of 
the audiologist, otolaryngologist or physician who is evaluating the audiogram, one of the 
following conditions exists:
1.
The standard threshold shift revealed by the audiogram is persistent
2.
The hearing threshold shown in the annual audiogram indicates significant improvement 
over the baseline audiogram
L.
Standard Threshold Shift
A standard threshold shift is a change in hearing threshold relative to the baseline audiogram of 
an average of 10dB or more at 2000, 3000, and 4000 Hz in either ear. A threshold shift that 
meets the OSHA definition of a hearing loss will be recorded on the OSHA Injury/Illness 300   
log by Risk Management. An Industrial Report of Injury must be filled out by the Supervisor 
immediately after notification of change.
M. Audiometric Test Requirements
1.
Audiometric tests shall be pure tone, air conduction, hearing threshold examinations, with 
test frequencies including at a minimum 500, 1000, 2000, 3000, 4000, and 6000 Hz. Tests 
at each frequency shall be taken separately for each ear.
2.   Audiometric tests shall be conducted in accordance to the OSHA Standard 29 CFR 
1910.05, Appendix C: Audiometric Measuring Instruments.

in OSHA Standard 29 CFR 1910.95, Appendix D: Audiometric Test Rooms. The functional 
operation of the audiometer shall be checked before each day's use by testing a person 
with known, stable hearing thresholds and by listening to the audiometer's output to make 
sure that the output is free from distorted or unwanted sounds. Deviations of 10 decibels or 
greater require an acoustic calibration.
N.
Hearing Protectors
1.
The County shall make hearing protectors available to all affected employees. Hearing 
protectors shall be replaced as necessary.
2.
The County shall require that hearing protectors be worn by affected employees, by those 
employees who have not yet had a baseline audiogram established, or by those employees 
who have experienced a standard threshold shift.
3.
Employees shall be given the opportunity to select their hearing protectors from a variety 
of suitable hearing protectors provided by the County.
4.

I.
PURPOSE
Employees who work outdoor or on job tasks where risk factors for heat illness are present, 
could develop heat illnesses if they do not protect themselves appropriately. The objective of 
this policy is to provide the basis for employee awareness regarding heat illness symptoms, 
methods to prevent illness and actions to take if symptoms occur.
II.
POLICY
A.
Affected employees are to do the following:
1.
Have drinking water and/or electrolyte replacement drinks available at all times when the 
environmental risk factors for heat illness are present

3.
Know the signs and symptoms of heat illnesses and monitor their own physical 
condition and that of their co-workers.
4.
Report any heat related illness symptoms to their supervisor.
B.
Management is to:
1.
Identify all employees who are required to work outdoors where heat illness could occur 
and identify the supervisor of the employees.
2.
Ensure that adequate potable water, ice and shade are available when the 
environmental risk factors for heat illness are present.
3.
Provide appropriate Personal Protective Equipment (PPE).
4.

D.
Heat Related Illnesses & Prevention:

Page 2 of 6
Policy Number:
A2234x
Policy Title:
HEAT ILLNESS PREVENTION
Current Adoption 
Date:
5-20-2015
It is important that all employees are adequately trained to enable them to understand and 
recognize the various types and causes of heat related illnesses. This will assist employees 
in preventing the occurrence of such illnesses and will enable them to provide immediate 
treatment to persons displaying the symptoms of heat related illnesses.
E.
Prevention is the best way to ensure that heat-related illnesses do not occur. This includes 
protecting the body from the effects of the sun and heat. Some factors that could lead to heat 
stress are:
1.
Sun exposure
2.
High temperatures and humidity
3.
Limited air movement
4.
Amount of physical exertion
5.
An individual’s physical condition
6.
Certain prescription and over the counter medications
7.
Inadequate tolerance of heat, hot work and poor acclimation
F.
The sun’s light contains ultraviolet (UV) light. It can cause injuries as mild as sunburn or as 
severe as skin cancer. It is important to prevent sunburn since this limits the ability of the skin to 
cool off the body by evaporation. To adequately block UV light, follow the instructions below:
1.Wear loose-fitting, long-sleeved shirts and long pants.
2.For any exposed skin, apply sunscreen that has a sun protection factor (SPF) of at least 30
3.Wear a hat with a sufficient brim to protect all areas of the face, ears and neck.
4.Wear UV-absorbent sunglasses to block UVA and UVB radiation. If safety glasses are 
required, ensure that the safety sunglasses meet these requirements.
5.Limit UV exposure between 10 a.m. and 4 p.m.
G. Heat by itself can be a serious health threat and even more so when it is combined with 
humidity such as during the monsoon season. Take the following precautions to prevent heat 
related illnesses:
1.
Wear loose-fitting, breathable clothing (such as cotton).
2.
Take short breaks, in shade or an air-conditioned location and rehydrate.
3.
Eat smaller meals before strenuous work in the heat.
4.
Alternate work/rest periods within the work group.
5.
Avoid caffeine, alcohol or large amounts of sugar.
6.
Understand that necessary safety equipment (gloves, overalls, hardhats, etc.) may 
hold in heat or not allow for effective skin evaporations which may increase heat load.
7.
Try to schedule outdoor tasks for the cooler part of the day when possible.
8.
Notify supervisors of any medical concerns; however, employees do not need to share 
specific details including prescribed medication.
H.
Proper fluid intake is essential to preventing heat related illnesses.
1.
Hydrate the day before working outdoors.
2.
Have cool drinking water available and close by the work area.
3.
Drink fluids with electrolytes during the day, in a 1:2 ratio with plain water.
4.
Limit fluid intake to no more than 1 ½ quarts per hour. Try to drink small 
amounts throughout the day rather than all at once.

5.
Caffeinated drinks and alcohol should be avoided as they will cause the body to lose fluids 
rather than to retain them.
III.
HEAT ILLNESSES
A.
Heat Stroke
1.
Heat stroke is the most serious heat related illness. It is a condition caused by prolonged 
exposure to high temperatures where the body can no longer control its temperature, and 
it can cause death or permanent disability. People with heat stroke experience high fever, 
headaches, hot dry skin and physical exhaustion. In extreme cases, a person may 
physically collapse and fall into a coma. When a person has heat stroke, emergency 
medical treatment must be sought immediately.
2.
Symptoms:
o
a.
Extremely high body temperature (106
b.
Red, hot and dry skin (no sweating)
c.
Rapid and strong pulse
d.
Throbbing headache
e.
Dizziness
f.
Nausea
g.
Confusion
h.
Unconsciousness
3.
Treatment:
F or higher)
a.
Immediately call 911 for emergency medical assistance. If possible, call Protective 
Services at (602) 506-2001.
b.
Move the person to a cool and shady area. Do not leave the person alone.
c.
Cool the person rapidly with running water, applying cold compresses and/or fanning.
d.
Provide cool water if they are alert. Avoid caffeine and alcohol.
e.
If the person is unconscious, do not give them water.
f.
Continue to cool their body until medical assistance arrives.
B.
Heat Exhaustion
1.
Heat exhaustion is a condition caused by the excessive loss of fluids due to sweating, 
resulting in the depletion of bodily fluids that creates an imbalance of the electrolytes in the 
body.
2.
Symptoms:
a.
Heavy sweating
b.
Paleness of skin
c.
Muscle cramps
d.
Tiredness
e.
Weakness
f.
Pulse rate may be fast but weak
g.
Breathing may be fast but shallow
h.
Headache

i.
Nausea or vomiting
j.
Fainting
3.
Treatment:
a.
Immediately call 911 for emergency medical assistance.
b.
Move the person suffering from heat exhaustion to a cool and shady area. Do not 
leave the person alone.
c.
Cool the person as quickly as possible with running water, applying cold 
compresses and/or fanning.
d.
If they are alert, give them cool drinking water, or electrolyte replacement drinks. 
Avoid caffeine and alcohol.
e.
Remove extra clothing when necessary and continue to cool their body until 
medical assistance arrives.
C.
Heat Cramps
1.
Heat cramps are painful spasms of the muscles generally thought to be caused by an 
imbalance of electrolytes in the body. This may occur when a person carries out 
strenuous physical activity, drinks large quantities of water, but fails to replace salts and 
electrolytes lost through sweating. Cramps can occur during or after working hours and 
may be relieved by drinking saline/electrolyte solutions.
2.
Symptoms include muscle pains or spasms usually in the abdomen, arms or legs.
3.
Treatment
a.
Stop all activity and sit in a cool and shady area.
b.
Drink a liquid containing sodium (e.g. electrolyte replacement drinks).
c.
Do not return to strenuous activity for at least a few hours after the cramps 
subside. Further exertion might lead to heat exhaustion or heat stroke.
d.
Seek medical attention if heat cramps do not subside within 1 hour.
D.
Heat Rash
Heat rash, also known as prickly heat, may occur in hot and humid environments where 
sweat is not easily removed from the surface of the skin by evaporation. When extensive, 
or complicated by infection, heat rash can be so uncomfortable that it inhibits sleep and 
impedes a worker’s performance or even results in temporary disability. In most cases, 
heat rashes will disappear when the affected individual returns to a cooler environment.
E.
Training
1.
All employees and their supervisors working on job tasks where environmental risk 
factors for heat illness are present shall receive instruction in heat illness prevention 
before being assigned to work tasks that subjects them to heat stress.
2.
Due to the nature of work in the County and the temperature extremes in Arizona, heat 
illness training shall be required annually for all field employees. Training topics shall 
include the following:

Appendix A
Water Jug Cleaning Instructions
•
To prevent stains, odors and mold/fungus/bacteria growth, empty the cooler of its contents after 
use, even if it has only had water in it.
•
The dispensers should be cleaned and sanitized at least once every 24 hours. For containers 
too large to be immersed in a sink, a clean and sanitize in-place procedure can be used. 
This includes use of a clean bucket and wash cloth for the detergent cleaning step, followed by 
rinsing the container at least three times with water, and finally, spraying the inside of the 
container and spigot with a sanitizer solution.
•
Wipe exterior surfaces clean daily before storing and between uses.
•
Light dirt or stains can be cleaned with water or mild detergent.
•
Tougher stains may be cleaned with a diluted solution of baking soda and water.
•
For set-in stains or odors, use gloves to wipe the inside of the cooler with a 5% 
bleach solution (1/2 cup per five gallons); rinse and let it dry thoroughly.
•
If the cooler is used with a sugar-based product make sure it is scrubbed and well 
cleaned out. Fungus and bacteria can grow quickly if there is sugar residue left in the 
cooler, especially when left out in the heat.
•
Ensure all cleaning agents are thoroughly rinsed and the cooler is dry before storage.
•
If the cooler has a pour spout, run the cleaning product through it. Store the cooler with the spout 
open to allow moisture to escape.
