People who work outdoors are more likely to become dehydrated and get heat-related illness.


If you feel faint or weak, STOP all activity and get to a cool place.

If you have to work while it’s hot outside:

  • Prevent heat illness with acclimatization.
  • Drink plenty of water, and don’t wait until you are thirsty to drink.
  • Avoid alcohol or liquids containing large amounts of sugar.
  • Wear and reapply sunscreen as indicated on the package.
  • Ask if tasks can be scheduled for earlier or later in the day to avoid midday heat.
  • Wear a brimmed hat and loose, lightweight, light-colored clothing.
  • Spend time in air-conditioned buildings during breaks and after work.
  • Encourage co-workers to take breaks to cool off and drink water.
  • Follow additional tips on how to prevent heat-related illness.
