Heat Illness Precautions

A new video from OSHA aims to inform workers of all ages about the importance of taking precautions against heat illness.

Dozens of workers die every year because of working in the heat, OSHA says. Most of those deaths take place in the first few days of working in the heat, which makes it especially important for employers to allow workers to build up gradual tolerance to the conditions.

Symptoms of heat illness include headache, nausea, dizziness, irritability, confusion, thirst, heavy sweating and a body temperature greater than 100.4° F.

OSHA emphasizes three preventive steps: water, rest and shade. The agency advises workers in hot conditions to drink water every 15 minutes, even if they do not feel thirsty. Workers should wear a hat and light-colored clothing, and rest in the shade to cool down.

“Taking these precautions can mean the difference between life and death,”
