The Biden administration is opening an effort across federal agencies to address the health impacts from heat, including the first ever labor standard aimed at protecting workers from extreme heat, as part of a growing recognition of the dangers posed by warming temperatures caused by climate change.

The Occupational Safety and Health Administration, part of the Labor Department, will draft its first rule governing heat exposure designed to protect those who work outdoors in agricultural, construction and delivery services as well as workers in warehouses, factories, and kitchens.

It comes after a summer that saw record heat waves in the Western United States and British Columbia, which scientists say were made more extreme by climate change. According to the National Weather Service, extreme heat is the nation’s No. 1 weather-related killer.
