Preventing and Responding to Heat Illness
Elements of Your Written Program and Effective Work Practices
PREVENTATIVE COOL DOWN REST PERIODS
- (d) Access to shade.
- (3) Employees shall be allowed and encouraged to take a preventative cool-down rest in the shade for a period of no less than five minutes at a time when they feel the need to do so to protect themselves from overheating. Such access to shade shall be permitted at all times. 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, but in no event less than 5 minutes in addition to the time needed to access the shade.
- (4) If an employee exhibits signs or reports symptoms of heat illness while taking a preventative cool-down rest or during a preventative cool-down rest period, the employer shall provide appropriate first aid or emergency response according to subsection (f) of this section.
T8CCR 3395(e) states the following:
- (e) High-heat procedures.
- (5) 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.
- (6) For employees employed in agriculture, the following shall also apply:
When temperatures reach 95 degrees or above, the employer shall ensure that the employee takes a minimum 10 minute net preventative cool-down rest period every two hours. The preventative cool-down rest period required by this paragraph may be provided concurrently with any other meal or rest period required by Industrial Welfare Commission Order No. 14 if the timing of the preventative cool-down rest period coincides with a required meal or rest period thus resulting in no additional preventative cool-down rest period required in an eight hour workday. If the workday will extend beyond eight hours, then an additional preventative cool-down rest period will be required at the conclusion of the eighth hour of work; and if the workday extends beyond ten hours, then another preventative cool-down rest period will be required at the conclusion of the tenth hour and so on. For purposes of this section, preventative cool-down rest period has the same meaning as “recovery period” in Labor Code Section 226.7(a).
- (h) Training.
- (1) Employee training. Effective training in the following topics shall be provided to each supervisory and non-supervisory employee before the employee begins work that should reasonably be anticipated to result in exposure to the risk of heat illness:
- (B) The employer's procedures for complying with the requirements of this standard, including, but not limited to, the employer’s responsibility to provide water, shade, cool-down rests, and access to first aid as well as the employees’ right to exercise their rights under this standard without retaliation.
Guidance, Best Practices and Warnings
Cool-down rests help workers to recover from the heat and prevent overheating. A preventative cool-down rest period is not the same as regularly scheduled or other rest breaks (see Benefits of Rest Breaks). An employee may opt to take a “preventative cool-down rest” in the shade to help the body relieve excess heat. Rest breaks help cool the body to eliminate the need for a preventative cool-down rest period. There are numerous ways to enhance cooling the body during the preventative cool-down rest periods and rest breaks (see Sufficient Amounts of Drinking Water and Shade and Other Cooling Measures).
The importance of prevention cannot be overstated. Employees waiting until symptoms appear before seeking shade and recovery are at significant risk of developing heat illness. Also, the progression to more serious illness can be rapid, and can include altered coordination and speech, mental confusion, unusual behavior, nausea, vomiting, hot dry skin, unusually profuse sweating, loss of consciousness, and seizures. The affected employee may be unable to self-diagnose these problems.Following information provides guidance to the employers on providing cool-down rest to their employees when needed:
- It is crucial that workers not be rushed while taking the cool-down rest.
- Water should be available in the rest area so that employees are encouraged to drink more water.
- The employee must be monitored during the cool-down rest and asked if he or she is experiencing any symptoms of heat illness including simple fatigue. If any signs or symptoms of heat illness are observed or reported, the employer must not order the employee back to work and must continuously observe the employee until the signs or symptoms have abated.
Common early signs and symptoms of heat illness may include, for example, pale skin, heavy sweating, headache, muscle cramps, and fatigue. If no sign or symptom of heat illness is observed or reported, monitoring may be periodic, not continuous.
- If an employee exhibits or complains of any sign or symptom of heat illness, first-aid procedures should be initiated without delay.
- If heat illness is suspected, emergency medical personnel should be contacted immediately. No employee with signs or symptoms of heat illness should be left unattended or sent home without being offered onsite first aid or provided emergency medical services, as discussed in subsection (f).
Providing Cool Down Rest Periods
When providing cool down rest periods make sure to:
A cool down rest period is not a substitute for the treatment of heat illness by medical personnel. The progression to serious heat illness can be rapid. The initial symptoms alone might be an indication of a serious heat exposure. Therefore, employees or supervisors should be encouraged never to discount any discomfort or symptoms they have noticed or are experiencing.
If any of the signs and symptoms of heat illness (e.g., headache, muscle cramps,
fatigue, fainting, seizures, unusual behavior, nausea or vomiting, hot dry skin,
or unusually profuse sweating) are recognized or experienced, they should be
reported immediately. Then, worksite first aid procedures should be initiated
by a trained and certified first aid provider followed immediately by emergency
response procedures as indicated by first aid assessment.
Because of extreme environmental conditions during high heat or a heat wave, the risk of developing heat illness is even greater. Employees’ physical and mental condition can change even more rapidly into a serious medical condition. Therefore, during high heat or a heat wave it is even more important not to discount any discomfort or symptoms of heat illness and to immediately report any of these problems to a supervisor.
In agriculture, when temperatures reach 95 degrees or above, the employer shall ensure that the employees take a minimum ten minute preventative cool-down rest period every two hours.
