First Aid for Heat Illness

New and returning workers need to build 

tolerance to heat (acclimatize) and take 

frequent breaks.

Follow the 20% Rule. On the first day, work 

no more than 20% of the shift’s duration at 

full intensity in the heat. Increase the 

duration of time at full intensity by no more 

than 20% a day until workers are used to

working in the heat.

illness happen during the first week of work.

every 20 minutes.

Watch Out for Each Other

Monitor yourself and others for signs of heat illness.

Find Shade or a Cool Area

Take breaks in a designated shady or cool location.

Take Rest Breaks

Take enough time to recover from heat given the 

temperature, humidity, and conditions.

Dress for the Heat

Wear a hat and light-colored, loose-fitting, and breathable 

clothing if possible.

If Wearing a Face Covering 

Change your face covering if it gets wet or soiled. Verbally 

check on others frequently.

Watch for any other signs of heat illness 

and act quickly. When in doubt, call 911.
