On March 2, 2020, in a joint effort, the U.S.Food and Drug Administration and the Centers for Disease Control and Preventiontook action to make more respirators, including certain N95s, available tohealth care personnel. Currently, the majority of respirators on the market areindicated for use in industrial settings. Today¡¯s action allows certainNational Institute for Occupational Safety and Health (NIOSH) approvedrespirators not regulated by the FDA to be used in a health care setting duringthe coronavirus (COVID-19) outbreak, thereby maximizing the number ofrespirators available to meet the needs of the U.S. health care system.
