The threat of heat stress is growing each year, emphasizing the need for protections for all workers.
According to Keenan Bell, temperatures in parts of the Bridgestone tire plant in Des Moines, Iowa, can reach 110 or 115 degrees during summer months due to steel-plate floors that "absorb heat and radiate it to no end".
The sweltering conditions pose a threat to the plant's 530 union workers, who also face molten rubber and heat-generating equipment while wearing protective gear.
