Heat Stroke

Heat stress creates many hazards in the workplace for those employees who have to work in a hot environment. Hot environments can create indirect safety hazards such as causing employees to lose focus on their work task or becoming fatigued. Heat stress also causes more direct illnesses such as heat cramps, heat exhaustion, and heat stroke. Deaths from heat-related issues between 2005 and 2009 rose to higher rates than any others observed during any other 5-year periods in the past 35 years. According to OSHA, 18 people died in 2014 due to heat-related issues.


Heat stroke is the most serious heat-related illness. This illness can kill or cause damage to the brain and other internal organs. Heat stroke results from prolonged exposure to high temperatures—usually in combination with dehydration—which leads to failure of the body’s temperature control system. If someone who is exhibiting signs of heat stroke is not properly treated immediately then there can be permanent health issues or death.

Prevention of Heat Illnesses:
  1. Allow for acclimation to hot environments. It can take two weeks before an individual’s body is used to working in a hot environment.
  2. Take plenty of breaks in a cool or shaded area.
  3. Drink plenty of water before you are thirsty.
  4. Keep an eye on coworkers. Monitor each other for signs of heat illness.
Signs of Heat Stroke:
  • Fainting may be the first sign
