Avoid Heat-Related Illness

With the heat of summer upon us, here are some recommendations for avoiding heat-related illnesses:

Workers should avoid exposure to extreme heat, sun exposure, and high humidity when possible. When these exposures cannot be avoided, workers should take the following steps to prevent heat stress:

• Wear light-colored, loose-fitting, breathable clothing such as cotton.
• Avoid non-breathing synthetic clothing.
• Gradually build up to heavy work.
• Schedule heavy work during the coolest parts of day.
• Take more breaks in extreme heat and humidity.
• Take breaks in the shade or a cool area when possible.
• Drink water frequently. Drink enough water that you never become thirsty.
• Avoid drinks with caffeine, alcohol, and large amounts of sugar.
• Be aware that protective clothing or personal protective equipment may increase the risk of heat stress.
• Monitor your physical condition and that of your coworkers.

If you know you will be working in a high heat area, discuss how to reduce its impact with your supervisor.  Hints for work planning can be found at:
