Working outdoors in hot weather can result in serious illness or even death. Workers exposed to extreme heat may experience symptoms of heat-related illnesses (HRI), such as heat cramps, heat rash, heat exhaustion, fainting, heat stroke and other symptoms.

Heat-related illness is also linked to injuries from falls, equipment operation accidents and other on-the-job incidents. Such incidents can happen when someone with heat stress becomes fatigued, dizzy, confused or disoriented.

Employers must provide training to workers so they understand what heat stress is, how it affects their health and safety, and how it can be prevented.
