Heat Illness Prevention

Employees working in the outdoors or in other spaces where environmental risk factors for heat illness are present are at great risk for injury if they do not take the necessary precautions to protect themselves.

Cal-OSHA requires that employers develop and implement a written Heat Illness Prevention plan that complies with T8 CCR §3395.

“Heat Illness” is a serious medical condition resulting from the body’s inability to cope with a particular heat load, and includes heat cramps, heat exhaustion, heat syncope and heat stroke.


Cal-OSHA requires that employers:

  • Provide plenty of cool, fresh water.
  • Provide a shaded area for workers to cool down.
  • Give workers a period of time to get used to the heat, especially during a heat wave or for new workers. This is known as “acclimatization”.
  • Train worker about heat illness and how to prevent it.
