Cal/OSHA Reminds Employers to Protect Outdoor Workers from Heat Illness

Oakland—Cal/OSHA is reminding all employers to protect outdoor workers from heat illness as the National Weather Service has issued heat advisories throughout the state this week. Employers in California must take steps to protect outdoor workers from heat illness by providing water, rest, shade and training.

Heat advisories are in effect through Friday for Santa Barbara, Ventura, Orange, Los Angeles, San Bernardino, Riverside and San Diego counties. The National Weather Service has also published information about the first 90 degree days arriving on average a month early this week in Redding, Sacramento, Stockton and Modesto. When working in these hotter conditions for the first time this year, workers should be closely observed for any signs of heat illness.

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 and maintain a written prevention plan with training on the signs of heat illness and what to do in case of an emergency.

It is important for employers to assess the risk of heat illness based on a worker’s duties and take appropriate steps to prevent them from getting sick. Regardless of the level of risk, all outdoor workers must be protected equally and employers with outdoor workers must maintain an effective heat illness prevention plan year-round.

Employers with outdoor workers in all industries must follow these heat illness prevention requirements:

  • Plan – Develop and implement an effective written heat illness prevention plan that includes emergency response procedures.
  • Training – Train all employees and supervisors on heat illness prevention.
  • 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 proper shade when temperatures exceed 80 degrees. Workers have the right to request and be provided shade to cool off at any time.

Cal/OSHA’s Heat Illness Prevention special emphasis program includes enforcement of the heat regulation as well as multilingual outreach and training programs for California’s employers and workers. Details on heat illness prevention requirements and training materials are available online on Cal/OSHA’s Heat Illness Prevention web page and the 99calor.org informational website. A Heat Illness Prevention online tool is also available on Cal/OSHA’s website.
