OSHA has expanded temporary guidance provided in a March 14, 2020, memorandum regarding supply shortages of N95s or other filtering facepiece respirators (FFRs) due to the COVID-19 pandemic. This expanded guidance applies to all workplaces covered by OSHA where there is required respirator use. OSHA field offices will exercise enforcement discretion concerning annual fit-testing requirements, as long as employers have made good-faith efforts to comply with the requirements of the Respiratory Protection standard and to follow the steps outlined in the March 14, 2020 memorandum.
