Page 3 of 4

Policy Number: A2234g
Policy Title:
POWERED INDUSTRIAL TRUCK PROGRAM Current Adoption
5-20-2015
Date:
A. Balance – The wheels of a lift truck act as balance points. They stabilize the truck between the load
in front and the counter weight in back. A truck loaded beyond its capacity can tip and cause serious
injury.
B. Steering – Most lift trucks are steered by the rear wheels. Lift trucks steer more easily loaded than
empty.
C. Loading and Unloading – Make sure the load is stable prior to moving. Move the lift truck carefully
into position and adjust the forks to the proper width. Drive forward until the forks are positioned into
the load. Always lift less than the load capacity stated on the capacity plate.
D. Lifting Loads – Lift the load slightly and back out. Do not maneuver or turn the truck while the forks
are raised. Lower the load within four inches of the floor. Tilt the mast back before you travel with the
load. Handle only loads that are stable and arranged properly. Stay in the center of aisles as you
travel.
VI. DRIVING TIPS
A. Keep hands, arms, and legs inside the truck. Obey posted speed limits and other signage.
B. Stop, sound your horn and proceed with caution at doorways, blind corners and intersections.
C. Be alert for other trucks and low overhead clearances.
D. Concentrate on operating your lift truck safely and keep a clear view.
E. If the load blocks your view, drive in reverse.
F. Do not let anyone stand or walk under elevated forks.
G. Do not let anyone ride on the lift truck or use the lift truck to lift people, unless you are authorized
and are using the proper attachments.
H. When traveling inclines and ramps, travel with the load uphill whether you are going up or coming
down.
I. Report any unsafe condition to your supervisor immediately.

I. PURPOSE
In compliance with OSHA Standard 29 CFR 1910.1030 (c)(l)(i), this program was developed
to limit employee’s occupational exposure to blood and other potentially infectious materials.
This program applies to any employee who can reasonably be expected to have contact with
blood or other bodily fluids in performances of their job duties.
II. DEFINITIONS
A. Bloodborne Pathogens (BBP): Pathogenic microorganisms that are present in human
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
parenteral contact with blood or other potentially infectious materials that may result from the
Page 1 of 8

Policy Title: Policy Number: A2234l
BLOODBORNE PATHOGENS EXPOSURE

CONTROL PLAN Date: 5-20-2015
performance of an employee's duties.
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
P. Source Individual means any individual, living or dead, whose blood or other potentially
infectious materials may be a source of occupational exposure to the employee. Examples
include, but are not limited to, hospital and clinic patients; clients in institutions for the
developmentally disabled; trauma victims; clients of drug and alcohol treatment facilities; residents
of hospices and nursing homes; human remains; and individuals who donate or sell blood or blood
components.
Q. Sterilize means the use of a physical or chemical procedure to destroy all microbial life including
highly resistant bacterial endospores.
R. Universal Precautions is an approach to infection control. According to the concept of Universal
Precautions, all human blood and certain human body fluids are treated as if known to be
infectious for HIV, HBV, and other bloodborne pathogens.
S. Work Practice Controls means controls that reduce the likelihood of exposure by altering the
manner in which tasks are performed (e.g., prohibiting recapping of needles by a two-handed
technique).

Date:
I. PURPOSE
This policy is intended to conform to applicable Center for Disease Control (CDC) guidelines and
Occupational Safety and Health Administration (OSHA) regulations as it pertains to preventing and
containing airborne pathogens.
II. DEFINITIONS:
A. Airborne Pathogens: Microorganisms that may be present in the air and can cause diseases in
exposed humans. These include, but are not limited to, mycobacterium tuberculosis (TB),
influenza, measles and the aspergillus fungus.
B. 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:
Page 1 of 8

Policy Number: A2234m
Policy Title:
AIRBORNE PATHOGEN EXPOSURE

CONTROL POLICY Date: 5-20-2015
a. A cough that lasts more than three weeks and produces sputum and blood
b. Chest pain
c. Fever, chills and night sweats
d. Easily tired, loss of appetite and weight loss
F. Personal Protective Equipment (PPE): Specialized clothing or instruments, such as high-
efficiency particulate air (HEPA) respirators used by an individual for protection against exposure
to an airborne pathogen.
G. Source Individual: Any individual, living or dead, who may be a source of exposure to
employees.

A. Maricopa County recognizes the danger that airborne pathogens pose to the health of its
employees due to a variety of environmental conditions and job duties. It shall be the
responsibility of each department to develop, document and implement an airborne pathogen
exposure control program. Airborne pathogens include, but are not limited to, tuberculosis
(TB), Legionella, meningococcal meningitis, diphtheria, rabies, plague and hemorrhagic fever.
Most, with the exception of TB, are rare in the United States. If any of these diseases are
suspected or confirmed, contact the Public Health Department.
This Exposure Control Plan clearly outlines the purpose, scope, responsibility, authorization,
rules, definitions and measures necessary for compliance. All affected County employees shall
comply with this plan.
B. It is the responsibility of each department to identify employees who are or may be exposed to
airborne pathogens. Each department shall implement measures designed to minimize exposure
and protect staff from airborne agents.
Each department’s Exposure Control Program shall comply with the recognized three-level
hierarchy of control measures:
2. Administrative Controls

I. 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.

EXCAVATION PROCEDURES Current Adoption
Date: 5-20-2015
J. Ramp: An inclined walking or working surface that is used to gain access to one point from
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 4 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.

Policy Number: A2234n
Policy Title:
EXCAVATION PROCEDURES Current Adoption
Date: 5-20-2015
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 6 of 8

Policy Number: A2234n
Policy Title:
EXCAVATION PROCEDURES Current Adoption
Date: 5-20-2015
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.

EXCAVATION PROCEDURES Current Adoption
Date: 5-20-2015
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.

RESPIRATORY PROTECTION PROGRAM Date:
Approved by: Board Agenda
Number:
BOARD OF SUPERVISORS Original Adoption
5-20-2015
Date:
I. PURPOSE
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
Page 1 of 10

Policy Number: A2234o
Policy Title:
RESPIRATORY PROTECTION PROGRAM Current Adoption
5-20-2015
Date:
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
Page 2 of 10

Policy Number: A2234o
Policy Title:
RESPIRATORY PROTECTION PROGRAM Current Adoption
5-20-2015
Date:
limitations and characteristics of the available respirators also are selection factors.
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.
Page 3 of 10

Policy Number: A2234o
Policy Title:
RESPIRATORY PROTECTION PROGRAM Current Adoption
5-20-2015
Date:
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

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.

diaphragms, demand and pressure-demand valve assemblies, hoses, or any components
recommended by the manufacturer. Discard or repair any defective parts.
2. Wash components in warm (43 deg. C [110 degrees F] maximum) water with a mild
detergent or with a cleaner recommended by the manufacturer. A stiff bristle (not wire)
brush may be used to facilitate the removal of dirt.
3. Rinse components thoroughly in clean, warm (43 degrees C [110 degrees F] maximum),
preferably running water. Drain.
4. When the cleaner used does not contain a disinfecting agent, respirator components
should be immersed for two minutes in one of the following:
a. Hypochlorite solution (50 ppm of chlorine) made by adding approximately one milliliter
of laundry bleach to one liter of water at 43 degrees C (110 degrees F)
b. Aqueous solution of iodine (50 ppm iodine) made by adding approximately 0.8

milliliters of tincture of iodine (6-8 grams ammonium and/or potassium iodide/100 cc of
45% alcohol) to one liter of water at 43 degrees C (110 degrees F.); or,
c. Other commercially available cleansers of equivalent disinfectant quality when used
as directed if their use is recommended or approved by the respirator manufacturer.
5. Rinse components thoroughly in clean, warm (43 degrees C [110 degrees F] maximum),
preferably running water. Drain. The importance of thorough rinsing cannot be
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.

INJURY AND ILLNESS PREVENTION PLAN:
Current Adoption
WELDING, CUTTING & HOT WORK 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

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.

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 3 of 5

Policy Title: Policy Number: A2234t
MACHINE SAFE GUARDING & TOOL
Current Adoption
SAFETY Date: 5-20-2015
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.

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.

BOARD OF SUPERVISORS Original Adoption
5-20-2015
Date:
I. 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.

Date:
D. Describe The Hazard
1. Supervisors and employees are responsible for reviewing the tasks/steps of each job
and analyzing hazards. Below is a list of the most common hazards in the work place:
a. General Safety Hazards:
i. Spills and tripping hazards
ii. Working at heights, including ladders, scaffolds, roofs, etc.
iii. Unguarded machinery and moving machinery parts
iv. Electrical hazards, including frayed cords, missing ground pins, etc.
v. Confined spaces
vi. Machinery related hazards including lockout/tagout boiler safety, etc.
b. Biological Hazards, unintended or excessive or unguarded exposure to:
i. Blood and other bodily fluids
ii. Fungi or mold
iii. Bacteria and viruses
iv. Plants
v. Insect bites
vi. Animal droppings
c. Physical Hazards

i. Liquids like cleaning products, paints, acids, solvents, etc.
ii. Vapors and fumes from welding
iii. Gasses like acetylene, propane, carbon monoxide and helium
iv. Flammable materials like gasoline, and explosive chemicals
v. Pesticides.
E. Determine Hazard Control Measures
The following controls should be incorporated into the tasks/steps:
1. Engineering controls help to eliminate or minimize the hazard by reducing its
potential severity and/or its likelihood of becoming an incident.
2. Administrative controls are written operating procedures, work permits and safe

Date:
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: http://ebc.maricopa.gov/RM/jsa_library.htm
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 MAINTENANCE
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.

Policy Number: A2234v
Policy Title:
WORKPLACE HAZARD ASSESSMENT Current Adoption
5-20-2015
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 1 of 5

Policy Title: Policy Number: A2234w
HEARING CONSERVATION PROGRAM Current Adoption
5-20-2015
Date:
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 2 of 5

Policy Title: Policy Number: A2234w
HEARING CONSERVATION PROGRAM Current Adoption
5-20-2015
Date:
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.
3. Audiometric examinations shall be administered in a room meeting the requirements listed

1. Have drinking water and/or electrolyte replacement drinks available at all times when the
environmental risk factors for heat illness are present
2. Have access to a cool/shaded area to prevent or recover from heat related symptoms.
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.

D. Heat Related Illnesses & Prevention:
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.

Date:
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:
a. Extremely high body temperature (106oF or higher)
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:
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

Date:
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.

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.
