Move the victims to a cool area. Place them on their backs with their feet raised. Loosen clothing and apply cool, moist cloths to the body, or fan the victim. Call a doctor, especially if victims faint or vomit. The body may either lose its ability to regulate temperature, due to a failure of the central nervous system to regulate sweat control, or its normal heat-regulating mechanism may simply be overwhelmed.
Heat stroke can result in coma or death.
A worker who becomes irrational or confused or collapses on the job should be considered a heat stroke victim, and medical help should be called immediately. Early recognition of symptoms and prompt emergency treatment is the key to aiding someone with heat stroke. Move the victim to a cooler environment and remove outer clothing. If no water is available, fanning will help promote cooling. Factors that may increase the risk of heat stress include sleep distress, obesity, poor physical condition, lack of acclimatization, dehydration, and alcohol use.
