                                                            Heat Stress Overview
                                            Workers who are exposed to extreme heat or work in hot
                                            environments may be at risk of heat stress. Exposure to
                                            extreme heat can result in occupational illnesses and
                                            injuries. Heat stress can result in heat stroke, heat
                                            exhaustion, heat cramps, or heat rashes. Heat can also
                                            increase the risk of injuries in workers as it may result in
                                            sweaty palms, fogged-up safety glasses, and dizziness.
                                            Burns may also occur as a result of accidental contact with
                                            hot surfaces or steam.

                                            Workers at risk of heat stress include outdoor workers and
                                            workers in hot environments. Workers at greater risk of heat
                                            stress include those who are 65 years of age or older, are
                                            overweight, have heart disease or high blood pressure, or
                                            take medications that may be affected by extreme heat.
                                            Prevention of heat stress in workers is important. Employees
                                            need to understand what heat stress is, how it affects their
                                            health and safety, and how it can be prevented.

                                                          Protect Yourself from Heat Stress
                                                Wear light-colored, loose-fitting, breathable clothing
                                                 such as cotton. Avoid non-breathing synthetic clothing.
                                                Gradually build up to heavy work.
                                                Schedule heavy work during the coolest parts of day.
                                                Take more breaks in extreme heat and humidity. Take
                                                 breaks in the shade or a cool area when possible.
How to Cool Down Properly
                                                Drink water frequently. Drink enough water that you

The goal is to get fluids back into your
body and get your body temperature
down so that your heat exhaustion does
not turn into heat stroke, which is far
more dangerous.
