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). The standard requires those employers to implement a written indoor heat illness prevention plan that includes procedures for accessing water and cool-down areas, acclimatization, training employees, and emergency response measures. Covered employers who have not already drafted and implemented their plan should do so immediately.
