Every year, thousands of workers become sick from heat exposure, and some even die. These illnesses and deaths are preventable.

Hazardous Heat

2When working in a hot environment it is important to maintain a stable internal body temperature. The body must get rid of excess heat to maintain a stable internal temperature. It does this mainly through circulating blood to the skin and through sweating (Occupational Heat Exposure, n.d.).

When the body cannot get rid of excess heat, it will store it. If this happens then the body's heart rate and temperature rises.

As the body continues to overheat, a person can begin to feel sick, irritability, fainting and even death if body does not cool down.  Too much exposure to heat can eventually cause a variety of illness.
