Hazard Alert: Heat Stress in Construction

Heat-related deaths and illnesses are preventable, but it’s important to identify the warning signs and to react swiftly and appropriately when they arise. Heat is a serious hazard in construction. Your body builds up heat when you work, and sweats to get rid of extra heat. But sometimes your body may not cool off fast enough. 

• Keep taking rest breaks. Rest in a cool, shady spot. Use fans.
• Stay Hydrated as much as you can, and ensure you have extra water available to workers.
• Wear light-coloured clothing made of cotton.
• Do the heaviest work in the coolest time of the day.
• Work in the shade.
• For heavy work in hot areas, take turns with other workers, so some can rest.
• If you work in protective clothing, you need more rest breaks. While on the job you should be monitored for heat-stress related symptoms, including changes in body temperature and heart rate.
• If you think someone has heat stroke, call emergency services (or 911). Immediately move the victim to the shade. Loosen his/her clothes. Wipe or spray his/her skin with cool water and fan him/her. You can use a piece of cardboard or other material as a fan.

Educate your workers on the difference between heat exhaustion vs. heatstroke:
