1.0 Scope

This Policy applies to all Fox Corporation (FOX) activities when temperatures exceed 80 degrees Fahrenheit when work is conducted outdoors and all indoor work areas where the temperature equals or exceeds 82 degrees Fahrenheit when employees are present. This plan addresses the measures that FOX will take to protect employees from heat-related illness.

2.0 Exceptions

Exceptions include outdoor or indoor workplaces where employees are teleworking from a location of the employee’s choice, heat exposures where an employee is exposed to temperatures above 82 degrees Fahrenheit for less than 15 minutes in any 60-minute period, as well as emergency operations directly involved in the protection of life or property. Locations outside of California are strongly encouraged to follow protocols outlined for indoor heat illness, but may not be required.

3.0 Definitions

Acclimatization:
A process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain performance across a range of environmental conditions. Acclimatization peaks in most people within four to fourteen days of regular work for at least two hours per day in the heat.

Administrative Control:
A method to limit exposure to a hazard by adjustment of work procedures, practices, or schedules. To minimize heat illness, administrative control can be utilized to acclimatize employees, rotate employees, schedule work earlier or later in the day, use work/rest schedules, reduce work intensity or speed, reduce work hours, and change required work clothing.

Clothing that Restricts Heat Removal:
A full-body clothing covering the arms, legs, and torso that is any of the following:

1. Waterproof; or
2. Designed to protect the wearer from a chemical, biological, physical, radiological, or fire hazard; or
3. Designed to protect the wearer or the work process from contamination.

Cool Down Area:
An outdoor area that is blocked from direct sunlight and shielded from other high radiant heat sources to the extent feasible and is either open to the air or provided with ventilation or cooling. A cool-down area does not include a location where:

• Environmental risk factors defeat the purpose of allowing the body to cool; or
• Employees are exposed to unsafe or unhealthy conditions; or
• Employees are deterred or discouraged from accessing or using the cool-down area.

Engineering Control:
A method of control that can remove or reduce hazardous conditions or can create a barrier between the employee and the hazard. To minimize heat illness, engineering control can be utilized to isolate hot processes, isolate employees from sources of heat, provide air conditioning, cooling fans, cooling mist fans, evaporative coolers, and/or natural ventilation.

Environmental Risk Factor for Heat Illness:
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, the ground, air movement, workload severity, and duration, protective clothing, and personal protective equipment worn by employees.

Globe Temperature:
The temperature measured by a globe thermometer, which may not be shielded from direct exposure to radiant heat while the globe temperature is being measured.

Heat Cramps:
Painful muscle spasms are caused when workers drink large quantities of water but fail to replace the body’s salt loss from sweating.

Heat Exhaustion:
A condition whose symptoms may include heavy sweating and a rapid pulse. It results from the loss of fluid from sweating when a worker has failed to drink enough fluids, take in salt, or both. Symptoms include extreme weakness or fatigue, dizziness, nausea, giddiness or headache. The skin is moist and flushed, and the body temperature is normal or slightly higher.

Heat Illness:
A serious medical condition that results from the body’s inability to cope with a particular heat load. Heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke are common medical conditions that result from heat illness.

Heat Index:
A measure of heat stress developed by the National Weather Service for outdoor and indoor environments that takes into account the dry bulb temperature and the relative humidity.

Heat Syncope:
Fainting or dizziness as a result of overheating.

Heat Stroke:
The most serious heat-related health issue. It is caused by the failure of the body to regulate its core temperature. Sweating may stop and the body is unable to rid itself of core heat. Symptoms include mental confusion, delirium, loss of consciousness, seizing, body temperature above 106 degrees Fahrenheit, and hot, dry skin which may be red or blotted. This is a life-threatening condition that requires immediate medical attention.

Heat Wave:
For the purpose of acclimatization, 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 daily outdoor temperature in the preceding five days.

High Radiant Heat Area:
A work area where the globe temperature is at least five degrees Fahrenheit greater than the dry bulb temperature.

High Radiant Heat Source:
Any object, surface, or other source of radiant heat that could raise the globe temperature of the cool-down area five degrees Fahrenheit or greater than the dry bulb temperature of the cool-down area.

Indoor:
A space that is under a ceiling or overhead covering that restricts airflow and is enclosed along its entire perimeter by walls, doors, windows, dividers, or other physical barriers that restrict airflow, whether open or closed.

Personal Heat Protective Equipment:
Equipment worn to protect the user against heat illness. Water-cooled garments, air-cooled garments, cooling vests, wetted over-garments, heat-reflective clothing, supplied-air personal cooling systems are all examples of personal heat protective equipment.

Personal Risk Factors for Heat Illness:
Factors such as an 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.

Preventative Cool Down Rest:
A rest that is taken in a cool-down area to prevent overheating.

Radiant Heat:
Heat that is transmitted by electromagnetic waves and not transmitted by conduction or convection. Sources of radiant heat include the sun, hot objects, hot liquids, hot surfaces, and fire.

Relative Humidity:
The amount of moisture in the air relative to the amount that would be present if the air were saturated.

Shade:
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 shadow defeats the purpose of shade, which is to allow the body to cool. 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.

Shielding:
A physical barrier between radiant heat sources and employees reduces the transmission of radiant heat.

Temperature:
The dry bulb temperature in degrees Fahrenheit obtainable by using a thermometer to measure the outdoor temperature in an area where there is no shade. While the temperature measurements must be taken in an area with full sunlight, the bulb or sensor of the thermometer should be shielded while taking the measurements, e.g., with the hand or some other object, from direct contact by sunlight.

Union Representative:
A recognized or certified collective bargaining agent representing the employees.

5. Modify work schedules to avoid the hottest time of the day.
6. Post emergency procedures

5.2.2 While Working

There are four keys to minimizing the risk of heat illness (acclimate, shade, water, and education). Implement the following:

1. Gradually increase workload (acclimate).
   • A supervisor or designee must closely observe all employees during a heat wave. Similarly, a supervisor or designee shall, for the first 14 days of the employee’s employment, closely observe any employee who has been newly assigned to a high-heat area.
2. Take frequent breaks in shaded areas. Popup tents/cooling stations should be provided if shade is naturally unavailable at the worksite (adequate shade). Shaded areas must have the following features:
   • Be either open to the air or provided with ventilation or cooling.
   • Have enough shade present to at least accommodate the number of employees on recovery, rest, or meal periods, so that they can sit in a normal posture fully in the shade without having to be in physical contact with each other.
   • Be located as close as practicable to the areas where employees are working.
     Indoor cool-down areas, if required, must:
   • Be at least large enough to accommodate the number of employees on recovery or rest periods, so that they can sit in a normal posture fully in the cool-down areas without having to be in physical contact with each other,
   • Be located as close as practicable to the areas where employees are working.
   • During meal periods the size of the cool-down area shall be at least large enough to accommodate the number of employees on the meal period who remain onsite.
   • Maintain a temperature at less than 82 degrees Fahrenheit, when feasible.
3. Drink plenty of water. This means at least one quart per hour for each worker (adequate water).
   • Employees shall always have access to free, potable drinking water. This drinking water should be fresh, pure, suitably cool, and located as close as practicable to the employees work areas. It is the supervisors responsibility to ensure that this occurs. Where drinking water is not plumbed or otherwise continuously supplied, then supervisors must ensure that personnel are assigned to provide drinking water that meets the following criteria:
     • Water must be provided at the start of each work shift in sufficient quantity that it can provide each employee with one quart of water per hour for the entire work shift
     • In the alternative, crew can begin the shift with smaller quantities of water if there is an effective procedure to replenish that water supply during shift, so as to allow employees to drink one quart or more per hour
4. Use the buddy system to monitor employees so employees do not work alone, if possible.
5. Regularly check high-risk employees.
   • Employees are allowed and encouraged to take a preventative cool-down rest in the shade whenever they feel the need to do so to protect themselves from overheating. Management shall permit such a preventative cool-down rest to be taken at any time. An employee who takes a preventative cool down rest:
     • Shall be monitored by a supervisor/buddy and asked if he/she is experiencing symptoms of heat illness
     • Shall be encouraged to remain in the shade
     • shall not be ordered back to work until any signs or symptoms of heat illness have abated, but in no event, less than five minutes in addition to the time needed to access shade.
   • If an employee exhibits signs or reports symptoms of heat-related illness while taking a preventative cool-down rest FOX shall provide appropriate first aid or emergency response, pursuant to this plan and any customized Emergency Response Procedure.
6. Continuously educate employees on the above procedures (educate). This includes:
   • Inform employees at the start of the workday as to provisions made for shade.
   • Inform employees throughout the workday to utilize shade, as needed.
   • Periodically monitor the worksite to ensure shade is adequate and being utilized, as needed.

6.0 Assessment and Control Measures

This section only applies to indoor work areas subject to one or more of the conditions listed below:

• The temperature equals or exceeds 87 degrees Fahrenheit when employees are present; or
• The heat index equals or exceeds 87 degrees Fahrenheit when employees are present; or
• Employees wear clothing that restricts heat removal, and the temperature equals or exceeds 82 degrees Fahrenheit; or
• Employees work in a high radiant heat area and the temperature equals or exceeds 82 degrees Fahrenheit.
• Exceptions:
  • Vehicles with effective and functioning air conditioning and
  • Those outlined in section 2.0 of this policy.

6.1 Control Measures

If any of the above conditions apply Supervisors shall measure the temperature and heat index, and record whichever is greater. Instruments used to measure the temperature or heat index shall be used and maintained according to the manufacturer’s recommendations. Instruments used to measure the heat index shall utilize Appendix A: NWS heat index table. FOX will also identify and evaluate all other environmental risk factors for heat illness. Records shall be recorded using Appendix B which include the date, time, and specific location of all measurements. Temperature and heat index measurements shall be taken as follows:

1. Initial measurements shall be taken when it is reasonable to suspect that this section applies where employees work and at times during the work shift when employee exposures are expected to be the greatest.
2. Measurements shall be taken again when they are reasonably expected to be 10 degrees or more above the previous measurements where employees work and at times during the work shift when employee exposures are expected to be the greatest.
3. Records, as required by this section are retained for 12 months or until the next measurements are taken, whichever is later. The records shall be made available to employees, designated representatives, and representatives of the Division at the worksite and upon request.

FOX has implemented effective procedures to obtain the active involvement of employees and their union representatives in the following:

1. Planning, conducting, and recording the measurements of temperature or heat index, whichever is greater.
2. Identifying and evaluating all other environmental risk factors for heat illness.

FOX shall use control measures as specified in this policy to minimize the risk of heat-related illness. The selection of control measures is based on the environmental risk factors for heat-related illness present in the work area.

6.2 Engineering controls

Engineering controls shall be used to reduce and maintain both the temperature and heat index to below 87 degrees Fahrenheit when employees are present, or to reduce the temperature to below 82 degrees Fahrenheit where employees wear clothing that restricts heat removal or work in high radiant heat areas, except to the extent that FOX demonstrates such controls are infeasible. When such controls are infeasible to meet the temperature and heat index thresholds, the following shall occur:

1. Use engineering controls to reduce the temperature, heat index, or both, whichever applies, to the lowest feasible level, where feasible.
2. Use engineering controls to otherwise minimize the risk of heat-related illness, where feasible.

6.3 Administrative controls

Where feasible engineering controls are not sufficient to reduce and maintain the temperature and heat index to below 87 degrees Fahrenheit when employees are present or the temperature to below 82 degrees Fahrenheit where employees wear clothing that restricts heat removal or work in high radiant heat areas, administrative controls shall be used to minimize the risk of heat illness, except to the extent that FOX demonstrates such controls are infeasible.

6.4 Personal heat-protective equipment (PPE)

Where feasible engineering controls are not sufficient to reduce and maintain the temperature and heat index to below 87 degrees Fahrenheit when employees are present or the temperature to below 82 degrees Fahrenheit where employees wear clothing that restricts heat removal or work in high radiant heat areas and feasible administrative controls do not minimize the risk of heat-related illness, personal heat-protective equipment shall be used to minimize the risk of heat illness, except to the extent that FOX demonstrates that use of such equipment is infeasible.

7.0 High Heat Procedures (Outdoors Only)

When the temperature equals or exceeds 95 degrees Fahrenheit outdoors, additional precautions must be followed. These procedures shall include the following to the extent practicable:

1. Ensure effective communication by voice, observation, or electronic means is maintained so that employees at the work site can contact a supervisor, when necessary. An electronic device, such as a cell phone or text messaging device, may be used for this purpose only if reception in the area is reliable.
2. Observe employees for alertness and signs or symptoms of heat-related illness. Effective employee observation/monitoring includes one or more of the following:
   • Supervisor or designee observation of 20 or fewer employees, or
   • Mandatory buddy system, or
   • Regular communication with sole employee such as by radio or cellular phone, or
   • Other effective means of observation such as preventative cool-down rests
3. Designate one or more employees on each location/venue as authorized to call for emergency medical services and allow other employees to call for emergency services when no designated employee is available.
4. Remind employees throughout the work shift to drink plenty of water.
5. Conduct a safety meeting 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.

8.0 Emergency Response

If signs or symptoms indicating severe heat-related illness such as, but not limited to, decreased level of consciousness, staggering, vomiting, disorientation, irrational behavior, or convulsions, then emergency response procedures must be followed as described below:

1. Seek medical assistance, if available onsite, or call 911 if unsure of the seriousness of the heat-related illness.
2. Alert a supervisor. That supervisor shall take immediate action commensurate with the severity of the illness whenever a supervisor observes, or any employee reports, any signs or symptoms of heat-related illness in any employee.
3. Do not leave the employee alone. An employee exhibiting signs or symptoms of heat-related illness shall be monitored and shall not be left alone or sent home without being offered onsite first aid and/or being provided with emergency medical services.
4. Move the employee to a cooler/shaded area.
5. Remove outer clothing and fan, mist, and apply ice.
6. If able to drink, provide cool drinking water.

Supervisors and employees will provide clear and precise directions to the worksite location of the employee needing assistance.

IF THE WORKER IS NOT ALERT OR SEEMS CONFUSED, CALL 911 IMMEDIATELY AND APPLY ICE.

9.0 Training

Effective training in the following topics shall be provided to Department Leadership and employees before they begin work, which should reasonably be anticipated to result in exposure to the risk of heat illness.

9.1 Employee Training, including:

1. The environmental and personal risk factors for heat illness, as well as the added burden of heat load on the body caused by exertion, clothing, and personal protective equipment.
2. Procedures for FOX’s responsibility to provide water, cool-down areas, cool-down rests, control measures, and access to first aid as well as the employees right to exercise their rights without retaliation
3. The importance of frequent consumption of small quantities of water, up to four cups per hour, when the work environment is hot, and employees are likely to be sweating more than usual in the performance of their duties
4. The concept, importance, and methods of acclimatization
5. The different types of heat-related illness, the common signs and symptoms of heat-related illness, and appropriate first aid and/or emergency responses to the different types of heat-related illness, and in addition, that heat-related illness may progress quickly from mild symptoms and signs to serious and life-threatening illness.
6. The importance of employees immediately reporting directly or through the employee’s supervisor, symptoms or signs of heat illness in themselves, or in co-workers.
7. Procedures for responding to signs or symptoms of possible heat-related illness, including how emergency medical services will be provided should they become necessary.
8. Procedures for contacting emergency medical services, and if necessary, for transporting employees to a point where they can be reached by an emergency responder.
9. Procedures for ensuring that, in the event of an emergency, clear and precise directions to the worksite can and will be provided as needed to emergency responders.

9.2 Department Leadership Training

In addition to the training outline in section 9.1, prior to supervising employees performing work that should reasonably be anticipated to result in exposure to the risk of heat-related illness, effective training on the following topics shall be provided to department leadership:

1. Procedures the supervisor is to follow to implement the applicable provisions outlined in section 5.2.
2. Procedures the supervisor is to follow when an employee exhibits signs or reports symptoms consistent with possible heat-related illness, including emergency response procedures outlined in section 8.0.
3. Where the work area is affected by outdoor temperatures, how to monitor weather reports, and how to respond to hot weather advisories outlined in section 7.0.
