The administration of U.S. President Joe Biden proposed new regulations aimed at protecting laborers working in extremely high temperatures as heat waves intensified by climate change increasingly blanket the nation.
The rule would be aimed at mail carriers, delivery people, construction workers, landscapers, restaurant staff and others exposed to consistently high heat indexes, which measures how the temperature actually feels to humans.
The measure – which would affect about 35 million workers, according to the government – would apply to those working both inside or outside who can expect to be exposed to a heat index of 80 degrees Fahrenheit (26 degrees Celsius) or higher.
"The purpose of this rule is to significantly reduce the number of worker-related deaths, injuries and illnesses suffered by workers who are exposed to excessive heat simply by doing their jobs," a senior administration official told reporters.
Under the rule, employers would be required to develop heat injury and illness prevention plans and appoint a workplace heat safety coordinator.
If the heat index were to hit 80 degrees Fahrenheit, workers would have to be provided with drinking water and access to break areas in the shade or in air-conditioned spaces.
Measures would also have to be implemented to allow for the "acclimatization" of employees who are either new or returning to work after illness, including more frequent breaks and a reduced workload until they are back up to speed.
"Three out of four workers who die on the job" due to heat-related illnesses "die in that first week on the job," the official said.
If finalized after a period of public debate, the rule would be the first such rule in the United States at the federal level.
If the heat index exceeded 90 degrees Fahrenheit, all employees would be allowed a 15-minute break every two hours, and managers would be required to monitor their workers for symptoms of heat-related illnesses.
Some workers, such as emergency medical personnel, would not be subject to the new rule.
The announcement, which comes as summer sets in across the U.S., is one of a series of measures the Biden administration has unveiled regarding extreme heat.
But the new work rule could be scrapped by a new administration should Biden not be reelected in November.
