Cal/OSHA's Heat Illness Prevention in Indoor Places of Employment regulation applies to most indoor workplaces, such as restaurants, warehouses, and manufacturing facilities. For indoor workplaces where the temperature reaches 82 degrees Fahrenheit, employers must take steps to protect workers from heat illness.
CALIFORNIA OCCUPATIONAL SAFETY AND HEALTH STANDARDS BOARD Add new Section 3396 to read: §3396. Heat Illness Prevention in Indoor Places of Employment. (a) Scope and Application. (1) This section applies to all indoor work areas where the temperature equals or exceeds 82 degrees Fahrenheit when employees are present.
California's new “Heat Illness Prevention in Indoor Places of Employment” standard is now in effect as of July 23, 2024. The new regulation applies to most California workplaces where the indoor temperature reaches 82°F or higher (e.g., warehouses, distribution centers, manufacturing plants, and restaurants).
There is no maximum temperature for workplaces. However, all workers are entitled to an environment where risks to their health and safety are properly controlled. Heat is classed as a hazard and comes with legal obligations like any other hazard. Find out what you should do to protect workers in high temperatures.
The law will apply to indoor work environments that reach or exceed a temperature of 82 degrees Fahrenheit when workers are present. Additional requirements will apply at 87 degrees or higher, when heat-restricted clothing is required, or the environment is considered a “high radiant heat area.”
The OSHA-NIOSH Heat Safety Tool App is a resource for finding the forecasted and current heat index near your location. The Heat App indicates the hazard levels using the HI as: Caution less than 80°F HI; • Warning 80°F to 94°F HI; and, • Danger at 95°F HI or higher.
Cal/OSHA's heat illness prevention standard applies to all outdoor worksites. To prevent heat illness, the law requires employers to provide outdoor workers fresh water, access to shade at 80 degrees, and, whenever requested by a worker, cool-down rest breaks in addition to regular breaks.
