Hot Take: Urgent Heat Crisis For Workers

By Juley Fulcher - Public Citizen, May 25, 2023

Key Findings

• Heat exposure is responsible for as many as 2,000 worker fatalities in the U.S. each year.
• Up to 170,000 workers in the U.S. are injured in heat stress related accidents annually. There is a 1% increase in workplace injuries for every increase of 1° Celsius.
• The failure of employers to implement simple heat safety measures costs the U.S. economy nearly $100 billion every year.
• The dangers of heat stress are overwhelmingly borne by low-income workers. The lowest-paid 20% of workers suffer five times as many heat-related injuries as the highest-paid 20%.
• Worker heat stress tragedies disproportionately strike workers who are low-income, Black or Brown.
• At least 50,000 injuries and illnesses could be avoided in the U.S. each year with an effective OSHA heat standard.
• Employers pay a substantial price for failing to mitigate workplace heat stress including the costs of absenteeism, turnover and overtime due to worker illness or injury, reduced worker productivity, damage to machinery and property from workplace accidents, increased workers’ comp premiums, law suits, and loss of public trust and customers.
• The physical and mental capacity of workers to function drops significantly as heat and humidity increase. Productivity of workers declines approximately 2.6% per degree Celsius above a Wet Bulb Globe Temperature (WBGT) of 24°C (75.2°F). The WBGT is a measure that combines temperature, relative humidity, radiant heat sources (like direct sunlight or heat-generating machinery) and wind speed.
• There are many simple ways employers can mitigate heat stress in the workplace, like access to cool drinking water and adequate “cool down” breaks in a shaded or air-conditioned space.
• It is essential that OSHA issue an interim rule to immediately prevent heat-related illness, injury and death in indoor and outdoor workers, both to protect workers and to reduce the clear burden on the economy.

The right to a safe workplace is a basic human right. Exposure to excessive heat is one of the most dangerous problems facing workers today. Tens of thousands of workers suffer heat illnesses, injuries and fatalities every year in the U.S. This is a toll disproportionately borne by Black and Brown workers, and low-income workers with limited options for safer employment. This is most clearly demonstrated by the plight of farmworkers, who have the highest rate of heat-related worker deaths, and are overwhelmingly immigrant workers with little power to demand workplace reforms from their employers.
