Workers exposed to extreme heat have no consistent protection in the US

State and federal agencies are scrambling to find measures to combat what experts call one of the harshest and most neglected effects of climate change in the U.S.: rising heat deaths and injuries of people who work in triple-digit temperatures.

But extreme heat protections for workers have generally lagged. Complicating attempts to address the issue is the absence of one national standard for measuring heat deaths in the U.S.
