The U.S. Occupational Safety and Health Administration on Wednesday said it cited a medical facility and a temporary staffing agency for failing to ensure the safety and health of nurses giving flu shots and COVID-19 tests.

In a statement, OSHA said an investigation into Lakewood Resource and Referral Center Inc. earlier this year found that the Lakewood, New Jersey-based facility did not provide medical evaluations to determine employees’ ability to use respirators before requiring their use and failed to fit test staff for the equipment.
