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.
