To prevent heat-related injury and illnesses while working in high-heat conditions in the workplace.

What Are The Risks?

The ultimate risk is heat stroke, which can result in death if not treated or treatment is delayed.

While this is rare, it is important to spot the early signs of heat stress before it progresses to heat stroke. More common heat-related concerns include heat exhaustion, heat cramps, fainting, and mental or physical fatigue which can increase the risk of errors or exposure to secondary hazards including, but not limited to – falls, struck-by’s, crushed-by’s, electrical, etc.

Long term risks include increased sensitivity to heat and heat illnesses.

Top 3 Ways to Avoid These Risks

Safe Work Practices - Overview

Heat-related illness risks increase when the heat index is 80 degrees Fahrenheit or there is a heat advisory or a heat warning from the National Weather Service.

Prepare for high heat conditions with the availability of water, shady areas for breaks, increased break times, and acclimatization methods.

Understand the symptoms of heat illnesses, including increased thirst, heavy sweating, dizziness, headache, nauseous, vomiting, cramping, hot dry skin, confusion, slurred speech, seizures, and loss of consciousness.

Take action when these symptoms are identified, including moving the person to a shady area, loosening clothing, offer cold liquid (water or electrolyte drink) to re-hydrate, and cool areas of the body by placing ice packs or ice on pulse points – head, neck, armpits, groin, and wrists.
