President Donald Trump’s nominee to head the nation’s workplace safety agency is a former safety executive for companies that were repeatedly cited by the same agency for worker illnesses and deaths amid extreme heat, according to federal records reviewed by the Lever.

If confirmed, David Keeling would be empowered to help his former employers’ multimillion-dollar lobbying campaign to kill state and federal heat protections — including a first-of-its-kind federal standard designed to protect workers from heat death amid rising global temperatures.

David Keeling, the nominee to lead the Occupational Safety and Health Administration (OSHA), previously helped oversee health and safety operations at companies including United Parcel Service (UPS) and Amazon, where workplace injuries and heat-related illnesses are common. In the six years that Keeling worked as a top safety executive at the two companies, OSHA fined the businesses a collective $2 million for more than three hundred workplace safety citations, including for heat-related illnesses as well as deaths that occurred amid extreme temperatures, the Lever found.
