Cal/OSHA advises employers to prevent heat illness as temperatures increase in Southern California

ADVISORY

As temperatures continue to rise this week, Cal/OSHA reminds all employers to protect their employees and prevent heat illness at indoor and outdoor workplaces by providing water, shade and rest breaks.

A heat advisory has been issued by the National Weather Service for areas of Southern California, including Los Angeles, Ventura and San Luis Obispo counties, starting on Tuesday, July 7. Temperatures are expected to be between 90-100 degrees Fahrenheit during the week, with the hottest temperatures expected on Wednesday and Thursday afternoon.

As summer temperatures rise, employers must remain vigilant and ensure that workers have access to water, shade or cool-down areas, and adequate rest breaks.

Heat illness is a serious and potentially fatal workplace hazard. Under Cal/OSHA's Heat Illness Prevention Standards, employers are legally required to protect workers from heat-related illness in both indoor and outdoor workplaces. Employers may be covered under both the indoor and outdoor regulations if they have workers in each setting. See the Comparison Chart of Indoor and Outdoor Heat Illness Prevention Standards for more information.

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, employers must take steps to protect workers from heat illness. Some of the requirements include providing water, rest, cool-down areas, and training.

To prevent heat illness at outdoor worksites, the law requires employers to provide outdoor workers fresh water, access to shade (which must be in place when temperatures exceed 80 degrees) and, whenever requested by a worker, cool-down rest breaks in addition to regular breaks. In certain industries, when the temperature at outdoor worksites reaches or exceeds 95 degrees, Cal/OSHA's standard requires additional protections. The industries with additional high-heat requirements are agriculture, construction, landscaping, oil and gas extraction, and transportation of agricultural products, construction materials or other heavy materials. High-heat procedures include ensuring employees are observed regularly for signs of heat illness and establishing effective communication methods.

Employers in both settings must also maintain a written prevention plan with effective training for supervisors and employees to recognize the common signs and symptoms of heat illness, and what to do in case of an emergency.
