Heat and Outdoor Workers
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.
