Heat Illness Prevention

Heat Illness is a serious medical condition resulting from the body’s inability to cope with a particular heat load and may include heat cramps, heat exhaustion, heat syncope, and heat stroke. This greatly impacts employees that work outdoors or in other spaces where environmental risk factors for heat illness are present.

To protect employees, employers are required by Cal/OSHA T8 CCR §3395 to develop and implement a Heat Illness Prevention Program (PDF).
