Under which circumstances is an N95 respirator required for staff?

N95 respirators are specifically used when there’s a risk of airborne transmission. They’re required for airborne precautions and during aerosol-generating procedures because these situations can release tiny, respirable particles that can stay suspended in the air and be inhaled. An N95 provides a higher level of filtration than a standard surgical mask, but it only works effectively if it fits properly, which is verified through fit testing. So the best guidance is to wear an N95 in settings with airborne precautions and during aerosol-generating procedures, ensuring a proper seal each time. This isn’t needed for routine patient interactions when only droplet precautions are in place, nor is it tied to cold seasons or to handling sharps.
