What OSHA says

Train all workers. Employers should train supervisors and workers on how to control and recognize heat hazards. Workers should also know about first aid for heat illness.

Follow the 20% rule. On a worker’s first day, no more than 20% of the duration of their shift should be at full intensity in the heat. The duration of time at full intensity should be increased by no more than 20% a day until workers are used to working in the heat.

Water. Rest. Shade. Workers should drink one cup of water every 20 minutes while working in the heat to stay hydrated. When the temperature is high, employers should make sure workers take frequent rest breaks in shaded, cool or air-conditioned areas.

Workers new to the job are at higher risk. Workers who are new or returning to working in warm or hot environments need more time to adapt.

Engineering controls and modified work practices can reduce the risk of heat illness. Consider reducing physical activity as much as possible by planning for the work ahead and rotating job functions among workers to help minimize exertion.
