Heat is the leading cause of death among all hazardous weather conditions in the United States. Excessive heat in the workplace can cause a number of adverse health effects, including heat stroke and even death, if not treated properly. According to the Bureau of Labor Statistics, 479 workers in the U.S. died from exposure to environmental heat from 2011-2022, an average of 40 fatalities per year in that time period. Additionally, there were 33,890 estimated work-related heat injuries and illnesses that resulted in days away from work from 2011-2020, an average of 3,389 per year in that time period. However, statistics for occupational heat-related illnesses, injuries, and fatalities are likely vast underestimates
