Outdoor and indoor heat exposure can be dangerous.
Here are ways to protect yourself and others:
- Ease into work. Nearly three out of four fatalities from heat illness occur during the first week of work.
- New and returning workers need to build tolerance to heat (acclimate) and take frequent breaks.
- Follow the 20 percent rule. On the first day, work no more than 20 percent of the shift’s duration at full intensity in the heat.
- Increase the duration of time at full intensity by no more than 20 percent a day until workers are used to working in the heat.
Drink Cool
- Drink cool water even if you are not thirsty. Drink at least 1 cup every 20 minutes.
Take Rest Breaks
- Take enough time to recover from the heat, given the temperature, humidity and conditions.
Find Shade or a Cool Area
- Take breaks in a designated shady or cool location.
Dress for the Heat
- Wear a hat and light-colored, loose fitting and breathable clothing, if possible.
Watch Out for Each Other
- Monitor yourself and others for signs of heat illness.
If Wearing a Face Covering
- Change your face covering if it gets wet or soiled. Verbally check on others frequently.
