California JPIA members are reminded to protect workers from heat illness as high temperatures are once again expected throughout California this summer. Employers must take steps to protect workers from heat illness in both indoor and outdoor workplaces under California Code of Regulations, Title 8, sections 3395 and 3396. California JPIA members may be covered under both the indoor and outdoor regulations if they have both indoor and outdoor workplaces.
Cal/OSHA’s Comprehensive Heat Illness Guidance and Resource Toolkit provides useful information on heat illness prevention, including a detailed comparison of outdoor and indoor workplace requirements. The standard commonly applies to agency employees who work in public works, maintenance, parks and recreation, community services, code enforcement, and public safety.
Heat illness prevention requirements are triggered when the temperature reaches 80 degrees for outdoor worksites and 87 degrees for indoor work areas (82 degrees when workers are wearing heat-restrictive clothing, such as clothing designed to protect from water, chemical, biological, and other hazards).
To prevent heat illness, employers are required to provide workers with fresh and suitably cool water, access to shade and/or cool-down areas, and, when needed, cool-down rest breaks in addition to regular breaks. Employers must also maintain a written prevention plan with effective training for supervisors to recognize the common signs and symptoms of heat illness and what to do in case of an emergency. Heat illness is more likely to occur when workers are not acclimatized to performing work at full capacity in hot weather. When working in these hotter conditions for the first time, workers must be closely observed for any signs of heat illness. Employers must also evaluate each worksite and make sure their workers know their procedures for contacting emergency medical services.
Members must take the following steps to prevent heat illness:
- Plan: Implement an effective written heat illness prevention plan.
- Training: Train all employees and supervisors on heat illness prevention, including common signs and symptoms of heat illness.
- Water: Provide drinking water that is fresh, pure, suitably cool, and free of charge so that each worker can drink at least 1 quart per hour and encourage workers to do so.
- Rest: Encourage workers to take a cool-down rest in the shade for at least five minutes when they feel the need to do so to protect themselves from overheating. Workers should not wait until they feel sick to cool down.
- Shade: Provide shade when workers request it or when temperatures exceed 80 degrees.
- Cool-Down Areas: For indoor workplaces, provide access to at least one cool-down area, which must be kept at a temperature below 82 degrees.
Members are encouraged to take advantage of the Authority’s training, which includes Cal/OSHA-compliant refresher training for employees and supervisors. Additionally, the Authority has developed a template Heat Illness Prevention Plan, available in the myJPIA library on the California JPIA’s website.
