One of the most common heat-related illnesses is heat exhaustion, which occurs when the body loses excessive water and salt through sweating. Symptoms may include heavy sweating, dizziness, weakness, headache, nausea, muscle cramps, cool or clammy skin, and a rapid pulse. If you or a coworker experiences these symptoms, move to a cool or shaded area immediately, drink cool water or an electrolyte-replacement beverage, loosen restrictive clothing, and rest.
Even more serious is heat stroke, a medical emergency that can be life-threatening. Signs include a body temperature above 103°F, confusion, slurred speech, hot and dry skin (or profuse sweating), seizures, or loss of consciousness. Call 911 immediately and begin cooling the person while waiting for emergency responders.
Hydration is one of the best defenses against heat illness. Advise them not to wait until they feel thirsty, that's often a sign they’re already becoming dehydrated. Drink water consistently throughout the day, especially before, during, and after working in hot conditions. For prolonged physical activity, electrolyte drinks may also be beneficial. Avoid excessive caffeine and alcohol, as both can contribute to dehydration.
Drink water frequently throughout their shift.
Take scheduled breaks in shaded or air-conditioned areas.
Wear lightweight, breathable clothing when appropriate.
During strenuous work, ensure they pace themselves and gradually build tolerance to hot conditions.
Look out for coworkers and encourage them to do the same.
Heat-related illnesses are preventable with proper planning and awareness. Staying hydrated, recognizing early warning signs, and taking breaks when needed are simple steps that can protect their health and keep everyone working safely. When it comes to working in the heat, prevention is always the best strategy.
