Cal/OSHA Reminds Employers with Outdoor Workers to Take Steps to Prevent Heat Illness

Oakland—Cal/OSHA is reminding all employers with outdoor workers to take steps to prevent heat illness and to review high temperature advisories and warnings in effect across California this week. The National Weather Service has issued excessive heat warnings for high temperatures in parts of San Diego, Imperial and Riverside counties, as well as heat advisories for many other parts of the state this week.

California’s heat illness prevention standard applies 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. 

Supervisors and workers must be trained on the signs and symptoms of heat illness so that they know when to take steps that can prevent a coworker from getting sick. Employers must also evaluate each worksite and make sure their workers know their procedures for contacting emergency medical services, which includes directing them to the worksite if needed. 

While taking steps to protect their workers from heat illness, employers must also have a plan to prevent the spread of COVID-19 at each worksite. 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. For many employers this will require staggered breaks or increased shaded break areas, or both. Extra infection prevention measures should be in place such as disinfecting commonly touched surfaces, including the water and restroom facilities. 

To help prevent the spread of COVID-19, employers should provide cloth face coverings or allow workers to use their own. Cloth face coverings are not personal protective equipment, but may help prevent the spread of the disease. Employers should be aware that wearing face coverings can make it more difficult to breathe and harder for a worker to cool off, so additional breaks may be needed to prevent overheating. Workers should have face coverings at all times, but they should be removed in outdoor high heat conditions when others are not nearby to help prevent overheating. The general workforce is not encouraged to use surgical masks or respirators as face coverings at this time. 

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. They should not wait until they feel sick to cool down.

Cal/OSHA’s Heat Illness Prevention special emphasis program includes enforcement of heat regulations as well as multilingual outreach and training programs for California’s employers and workers. Detail 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.
