illnesses, injuries, and reduced productivity can occur with excessive
exposure to a hot work environment. Heat-induced disorders include transient
heat fatigue, heat rash, fainting, heat cramps, heat exhaustion, and
heat stroke. Aside from these disorders, heat poses the threat of injuries
because of accidents caused by slippery palms as a result of sweating,
fogged up safety glasses, and dizziness. Severe burns can also occur
as a direct result of accidental contact with hot surfaces and steam.

illnesses, injuries, and reduced productivity, as well as methods that
can be taken to reduce risk.

Working in Hot Environments
DHHS (NIOSH) Publication No. 86-112 (April 1986)
