When a person works in a hot environment, the body tries to rid its self of excess heat by sweating. This enables the body to maintain a stable internal temperature. Heat related illness occurs when the body cannot cool it’s self down properly and begins to fall into different stages of heat illness.

Other factors to consider• What kind of and how hard are you working?• Are you taking any medications?• Types of clothing and personal protective gear.• Your age.• Heat can build up quickly in enclosed areas such as your car

and some buildings.• Also factor in the humidity as well as the temperature. The

combination of high levels of heat and humidity actually creates a higher ambient temperature or heat factor.

First aid Dial down the activities you do during hot days. Stay hydrated with water or sport drinks (with electrolytes are

even better). Have fluids at regular intervals; 1 cup every 15 minutes or 1 quart every hour.

If you see or sense symptoms, take breaks in the shade, more fluids.

Remove excess clothing (PPE) when not needed. Try to cool down the person as quickly as possible. Misting

with water and providing a breeze will be very effective. If condition appears to get worse, call 911 and if available start

applying icepacks to forehead, armpits, neck, groin areas.
