Why extreme heat is so deadly for workers

By Siri Chilukuri - Grist, July 25, 2023

Climate change is creating dangerously hot conditions for construction workers, mail carriers, delivery drivers, airline workers, farmworkers, and more. Conditions that were previously uncomfortable are now unbearable, and the failure of companies — along with some state governments — to catch up to the new normal of heat has had deadly consequences. 

U.S. heat-related fatalities have increased in recent years, according to an NPR analysis of Bureau of Labor Statistics data that found the three-year average of worker heat deaths has doubled since the early 1990s. In the decade spanning 2011 to 2021, heat killed more than 436 people on the job. 

The myriad of factors that influence how heat is actually felt can be difficult to pin down, but a metric known as the heat index — which combines temperature and humidity — can get close. Last week’s heat index figures were eye-popping, reaching 119 degrees Fahrenheit in Corpus Christi, Texas, and 113 F in both Phoenix and Baton Rouge, Louisiana. 

“The heat index is what really worries me,” said Tevita ’Uhatafe, a former airlines-operation worker who’s now the vice president of the Texas chapter of the AFL-CIO union. “Because that’s what we’re actually dealing with when we’re working outside.” 

Airline-operations positions often mean working outdoors with limited shade. Plus, being surrounded by the sheet metal of airplanes and the concrete of the tarmac can make it even hotter during periods of extreme heat. Concrete, for example, can actually contribute to rising temperatures. 

By mid-century, a quarter of Americans will experience heat index temperatures above 125 F for at least one day a year, according to a statistical model by the nonprofit First Street Foundation. Areas surrounding the Texas-Mexico border will experience temperatures above 100 F for more than a third of the year. In addition, researchers from the Union of Concerned Scientists and the University of California Merced found that outdoor workers stand to lose more than $39.3 billion in income annually by the middle of the century from reduced hours due to heat risk.
