According to BLS data from the Injuries, Illnesses, and Fatalities program, high temperatures can be dangerous to people at work and can lead to injuries, illnesses, and death. OSHA states that Supervisors and workers should be trained about heat hazards. They should also learn about prevention and first aid. Topics in this course include types of heat-related illness, including how to recognize common signs and symptoms, importance of immediately providing first aid to affected workers, procedures for contacting emergency medical services, importance of protecting new “unacclimatized” workers and work practices to help workers develop acclimatization.
