On a hot summer day in Oak Ridge, Tennessee, dozens of men removed pipes, asbestos and hazardous waste while working to decontaminate a nuclear facility and prepare it for demolition.
Dressed in head-to-toe coveralls and fitted with respirators, the crew members toiling in a building without power had no obvious respite from the heat. Instead, they wore armbands that recorded their heart rates, movements and exertion levels for signs of heat stress.
Stephanie Miller, a safety and health manager for a U.S. government contractor doing cleanup work at the Oak Ridge National Laboratory, watched a computer screen nearby. A color-coding system with little bubbles showing each worker’s physiological data alerted her if anyone was in danger of overheating.
"Heat is one of the greatest risks that we have in this work, even though we deal with high radiation, hazardous chemicals and heavy metals," Miller said.
