To combat the dangers of heat exposure, OSHA reminds employers and workers not to ignore the dangers of working in hot weather – indoors and out. Incorporating water, rest and shade can be the difference between ending the workday safely or suffering serious injuries or worse.
OSHA and NIOSH have released a free app, OSHA-NIOSH Heat Safety Tool, that calculates a worksite's heat index and shows the associated risk levels. Users will see precautionary recommendations specific to heat index risk levels to help protect employees from heat-related illness.
OSHA's Occupational Heat Exposure page explains the symptoms of heat illness, first aid measures to provide while waiting for help, engineering controls and work practices to reduce workers' exposure to heat, and training.
