Heat Stress

Construction workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes.

Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes.

Heat can also increase the risk of injuries in workers as it may result in sweaty palms, fogged-up safety glasses, and dizziness. Burns may also occur as a result of accidental contact with hot surfaces or steam.

  • When possible, acclimatize response and recovery workers to hot and humid environments by gradually increasing their work period or workload over the course of several days.
  • Reduce physical exertion levels by providing extra individuals.
  • Schedule heavy work for cooler periods of the work shift (e.g., early mornings, cool/overcast days).
  • When possible, provide temperature-controlled cabs for equipment operators.
  • When possible, and where appropriate, use fans/ventilation to provide air movement for cooling.
  • Take frequent rest/water breaks in areas that are shaded or air conditioned.
