HEAT RELATED ILLNESS SAFETY PROGRAM

1.

Purpose:

1.1 To provide a safe and healthful working environment and protect
Therma employees who are exposed to temperature extremes,
radiant heat, humidity, or limited air movement while working from
heat related illnesses.

2.

Policy:

2.1 The workplace will be evaluated to determine if Therma employees
are at high risk from heat related illnesses during temperature
extremes and hot weather while working. If it is determined
employees are at risk they will be trained to be aware of the heat
related illnesses, and procedures to take if symptoms are present.

2.2 This program shall be made available to all employees.

2.3 Therma shall develop and maintain a Heat Illness Prevention Plan.
The plan shall, at a minimum, consist of; procedures for the provision of water and access to shade; high heat procedures;
emergency response procedures; acclimatization methods; training
requirements. The plan shall be available to employees at the worksite, as well as to representatives of Cal/OSHA upon request. The plan will be considered available at the worksite if, it can be displayed for employees on a cell phone or other electronic device upon request.

3.

Implementation of Therma Heat Stress Program:

3.1 Therma will implement this Heat Stress Program when employees
are at risk of heat related illnesses while they are working and are
exposed to a combination of environmental risk factors such as
temperature extremes, radiant heat, humidity, limited
air movement, protective clothing, workload severity and duration.

4.

Training:

4.1 Training will be provided prior to job assignment.

4.2 Employee training: Training in the following topics will be provided
to all supervisory and non-supervisory employees:

4.2.1 Environmental and personal risk factors for heat illness.

4.2.2 Procedures for identifying, evaluating, and controlling
exposures to the environmental and personal risk factors for
heat illness.

4.2.3 The importance of frequent consumption of water.

4.2.4 The concept, importance, and method of acclimatization.

4.2.5 The different types of heat illness and the common signs
and symptoms or signs of heat illness.

4.2.6 The importance of immediately reporting to the employer or
designee symptoms or signs of heat illness.

4.2.7 Procedure for responding to symptoms of possible heat
illness, including how emergency services will be provided
should they become necessary.

4.2.8 Procedure for contacting emergency medical services, and if
necessary, for transporting employees to a point where they
can be reached by medical service personnel.

4.2.9 How to provide clear and precise directions to the work site.

4.2.10 Therma’s responsibility to provide water, shade, cool-down
rests, and access to first aid as well as the employees’ right
to exercise their rights without retaliation.

4.3 Supervisor training: Prior to assignment to supervision of
employees working in the heat, training on the following topics will
occur:

4.3.1 The information provided for employee training.

4.3.2 Procedures the supervisor will follow to implement controls
as determined by the employer.

4.3.3 Procedures the supervisor will follow when an employee
exhibits symptoms consistent with possible heat illness,
including emergency response procedures.

4.4 Training records shall be maintained for a period of no less than 3
years

5.

Controls for reducing heat exposure:

5.1 Therma’s supervisors will evaluate the potential for heat stress. If
environmental conditions are present the supervisor will implement
controls, such as; work/rest regimen, starting jobs earlier and
ending earlier to avoid hot times of the day, and/or, provisions for
gaining access to shade.

5.2 Acclimatization: Acclimatization means temporary adaptation of the
body to work in the heat that occurs gradually when a person is
exposed to it. Acclimatization peaks in most people within four to
fourteen days of regular work for at least two hours per day in the
heat. In fully acclimatized individuals, sweating starts faster and the
sweat carries less salt and other minerals out of the body. As a
result, by sweating more efficiently the body cools down faster.
Also there is less demand on the heart and cardiovascular system.
For the reasons given above, being fully acclimatized can allow
workers to continue working in warm or hot conditions and
decreases the risk of heat illness and unsafe acts.

5.2.1 Methods to acclimatize employees who are working in hot
environments:

• If they are not accustomed to working in warm or hot
environments, they should start work slowly and pick up
the pace gradually.

• Assign employees to less physically demanding tasks
during their first 14 days of working in a warm or hot
environment.

• Schedule and provide frequent breaks. Supply sufficient
amounts of drinking water

• Any employee who has been newly assigned to a hot
environment shall be closely observed by a supervisor or
designee for the first 14 days of the employee's
employment.

6.

Provisions for water:

6.1 An adequate supply of fresh, pure, and clean, and suitably cool
potable drinking water shall be located as close as practicable to
the areas where employees are working and will be supplied to
employees per safety standards. Employees will be notified of the
location of potable water and encouraged to drink. Where it is not
plumbed or otherwise continuously supplied, it shall be provided in
sufficient quantity at the beginning of the work shift to provide one
quart per employee per hour for drinking for the entire shift.

7.

Access to Shade:

7.1 The company shall provide access to shade when the temperature
reaches 80 degrees or upon request by employee when
temperature is below 80 degrees. Shade can be in the form of
“pop-ups”, umbrellas, or tree-covered areas*. Employees shall be*
allowed and encouraged to take a preventative cool down rest in
the shade whenever they feel the need to do so to protect them*
from overheating.

7.2 An individual employee who takes a preventative cool-down rest (A)
shall be monitored and asked if he or she is experiencing symptoms
of heat illness; (B) shall be encouraged to remain in the shade; and
(C) shall not be ordered back to work until any signs or symptoms
of heat illness have abated. If an employee exhibits signs or reports*
symptoms of heat illness while taking a preventative cool-down*
rest, the employer shall provide appropriate first aid or emergency
response.

7.3 Access shall be permitted at all times.

7.4 Locate the shade structure as close as practicable to the areas
where employees are working.

7.5 “Rule of Thumbs”: The amount of shade present should be at least
enough to accommodate the number of employees on recovery or
rest periods. The amount of shade present during meal periods
shall be at least enough to accommodate the number of employees
on the meal period who remain onsite.

8.

High Heat Procedures:

8.1 In the event temperatures equal or exceed 95 degrees Fahrenheit,
the following procedures shall be implemented:

• Ensure communication methods are available so
employees can contact their supervisors when
necessary.

• Supervisors shall observe employees for alertness and
sign / symptoms of heat illness by implementing one or
more of the following:

o Supervisor or designee observation of 20 or
fewer employees, or*

o Mandatory buddy system, or

o Regular communication with sole employee
such as by radio or cellular phone, or*

o Other effective means of observation.

• Pre-shift meetings before the commencement of work to
review the high heat procedures, encourage employees
to drink plenty of water, and remind employees of their*
right to take a cool-down rest when necessary.

• Designating one or more employees on each worksite
as authorized to call for emergency medical services,
and allowing other employees to call for emergency*
services when no designated employee is available.

• Reminding employees throughout the work shift to drink
plenty of water.

9.

First Aid awareness and actions in the event of a heat related illness:

9.1 Procedures for contacting emergency responders for heat illness
emergencies shall be established in the Site Medical Plan. This
plan shall be posted and clearly communicated to employees prior
to the start of work.

9.2 Remote Locations: The beginning of each day the supervisor shall
evaluate his/her work site to determine if transportation from a
remote location to a location where they could be reached by an
emergency medical responder if an emergency occurs. These
procedures shall be included in the Site Medical Plan.

9.3 The following chart helps employees recognize the main type of
heat related illnesses, symptoms, and the appropriate treatment to
reduce the effects of the heat related illness.

10. Definitions

10.1 “Heat Related Illness” – means a serious medical condition
resulting for the body’s inability to cope with a particular heat load,
and includes heat cramps, heat exhaustion, heat
syncope (fainting) and heat stroke.

10.2 “Environmental risk factors for heat illness” – means working
conditions that create the possibility that heat illness could occur,
including air temperature, relative humidity, radiant heat from the
sun and other sources, conductive heat sources such as ground,
air movement, workload severity and duration, protective clothing
and personal protective equipment worn by employees. These
conditions will be considered when determining that Therma is
implementing controls and methods to reduce the potential for heat
related illness.

10.3 “Personal risk factors for heat illness” – means factors such as
individual’s age, degree of acclimatization, health, water
consumption, alcohol consumption, caffeine consumption, and use
of prescription medications that affect the
body’s water retention or other physiological responses to heat.

10.4 “Shade” – means blockage of direct sunlight. One indicator that
blockage is sufficient is when objects do not cast a shadow in the
area of blocked sunlight. Shade is not adequate when heat in the
area of shade defeats the purpose of shade, which is to allow the
body to cool. For example, a car sitting in the sun does not provide
acceptable shade to a person inside it, unless the car is running
with air conditioning. Shade may be provided by any natural or
artificial means that does not expose employees to unsafe or
unhealthy conditions and that does not deter or discourage access
or use.

10.5 “Heat wave” - Any day in which the predicted high temperature for
the day will be at least 80 degrees Fahrenheit and at least ten*
degrees Fahrenheit higher than the average high daily temperature*
in the preceding five days.
