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

California, which has its own OSHA-approved workplace safety and health program, is reminding employers to review high temperature advisories in effect across the state.The National Weather Service has issued excessive heat warnings for many parts of the San Francisco Bay area and parts of northern Los Angeles County.

One of only three states with a heat illness prevention standard — the other two being Minnesota and Washington  — California's heat stress regulations apply to all outdoor workers, including those in agriculture, construction and landscaping. Other workers protected by the standard include those that spend a significant amount of time working outdoors such as security guards and groundskeepers, or in non-air conditioned vehicles such as transportation and delivery drivers.

COVID Is Also a Concern

According to CAL/OSHA, given the current pandemic, employers must assess each worksite and protect their workers from heat illness while also taking steps to prevent the spread of COVID-19, which is currently widespread in the community and considered a workplace hazard. Employers should be attentive to allow enough space and time for employees to take breaks as needed in adequate shade while also maintaining a safe distance from one another. Extra infection prevention measures should be in place such as disinfecting commonly touched surfaces, including the water and restroom facilities.

Employers with outdoor workers must take the following steps to prevent heat illness:

  • 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.
  • Shade – Provide shade when workers request it or when temperatures exceed 80 degrees. 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. They should not wait until they feel sick to cool down.
