OSHA has released a proposed rule with the goal of protecting workers from extreme heat. If finalized, OHSA projects the rule would affect approximately 36 million workers in indoor and outdoor work settings and substantially reduce heat injuries, illnesses and deaths in the workplace.
The proposed rule would require employers to develop an injury and illness prevention plan to control heat hazards in workplaces affected by excessive heat. Among other things, the plan would require employers to evaluate heat risks and — when heat increases risks to workers — implement requirements for drinking water, rest breaks and control of indoor heat. It would also require a plan to protect new or returning workers unaccustomed to working in high-heat conditions. Employers would also be required to provide training, have procedures to respond if a worker is experiencing signs and symptoms of a heat-related illness, and take immediate action to help a worker experiencing signs and symptoms of a heat emergency.
The agency continues to conduct heat-related inspections under its National Emphasis Program – Outdoor and Indoor Heat-Related Hazards, launched in 2022. The program inspects workplaces with the highest exposures to heat-related hazards proactively to prevent workers from suffering injury, illness or death needlessly. Since the launch, OSHA has conducted more than 5,000 federal heat-related inspections.
