Indoor Heat Illness Prevention

Cal/OSHA's Heat Illness Prevention in Indoor Places of Employment regulation applies to most indoor workplaces, such as restaurants, warehouses, and manufacturing facilities where temperatures can get high.

For indoor workplaces where the temperature reaches 82 degrees Fahrenheit, employers must take steps to protect workers from heat illness. Some of the requirements include providing water, rest, cool-down areas, methods for cooling down the work areas under certain conditions, and training.

Employers may be covered under both the indoor and outdoor regulations if they have both indoor and outdoor workplaces. See the Comparison Chart of Indoor and Outdoor Heat Illness Prevention Standards.
