“Millions of U.S. workers are exposed to heat in the workplace, and although heat-related illness is preventable, each year thousands of workers are getting sick from their exposure to heat, and … some cases are fatal,” Stephen Boyd, deputy regional administrator for OSHA Region 6, said May 19 during an OSHA webinar on preventing heat-related illnesses and injuries.
Working in a hot environment can trigger ailments that include heat rash, heat cramps, heat exhaustion and heatstroke – considered a medical emergency. Symptoms of heat exhaustion include feeling faint or dizzy; excessive sweating; cool, pale, clammy skin; nausea or vomiting; rapid, weak pulse; and muscle cramps. Workers who are experiencing heat exhaustion need to get to a cool, air-conditioned place. If fully conscious, they should drink water, take a cool shower and use a cold compress.
Workers with heatstroke may experience a headache but no sweating, and have a body temperature above 103° F. Other symptoms are red, hot, dry skin; nausea or vomiting; and loss of consciousness. Call 911 if a case of heatstroke is suspected, then take action to cool the worker until help arrives.
Other tips from OSHA to help prevent heat-related illnesses include:
- Drink water every 15 minutes.
- If working outside, take rest breaks in the shade to cool down.
- Wear a hat and light-colored clothing when working outdoors.
- Monitor co-workers for symptoms of heat-related illnesses.
