Preventing Heat Illness
Heat-Related Stress and Illness
Hot summer months pose special hazards for outdoor workers. Construction workers are prone to heat stress in various high temperature settings, such as on rooftops, or in open excavation sites which may lack air movement. Heat-related illness may initially manifest itself as a rash or cramps, but can quickly escalate to heat exhaustion and heat stroke if simple preventative measures are not followed.

- Heat stress can lead to heat-related illnesses such as heat exhaustion and heat stroke.
Symptoms of Heat Exhaustion:
