Federal OSHA is warning Arizona, South Carolina, and Utah that they risk a federal takeover of their worker safety programs unless they adopt a federal standard protecting health-care workers from Covid-19.

Of the 21 states with worker safety agencies approved by the U.S. Occupational Safety and Health Administration, the three states were the only ones that didn’t adopt the federal standard or their own version after it was issued June 21, Jim Frederick, OSHA’s acting administrator, said Tuesday during a press conference.

The announcement comes as OSHA is rushing to complete an emergency temporary standard mandating employers with 100 or more employees require workers to be vaccinated or tested at least weekly.
