Officials with the Occupational Safety and Health Administration are threatening to assert jurisdiction over workplace safety in three states that havent adopted President Joe Biden s emergency regulation for health care facilities .

South Carolina, Arizona and Utah all have what are known as OSHA state plans. Federal OSHA oversees workplace safety around the country, but states are allowed to handle it on their own as long as they meet minimum federal requirements.

OSHA officials said Tuesday that those three states had missed the deadline to implement the Biden administrations new rule meant to protect health care workers from COVID-19. If they dont implement such a rule, the administration will move to revoke approval of their state OSHA plans which would subject employers in South Carolina, Arizona and Utah to federally run inspections.

OSHA has worked in good faith to help these three state plans to come into compliance, Jim Frederick, the acting head of OSHA, said Tuesday on a call with reporters. But their continued refusal is a failure to maintain their state plan commitment to thousands of workers in their states.
