Recommendations for Personal Protective Equipment.

Minimum droplet-precaution PPE	Minimum airborne-precaution PPE
•Gloves •Short-sleeved apron •Fluid-resistant surgical mask •Eye and face protection (fluid-resistant surgical mask with integrated visor or full-face shield/visor or polycarbonate safety glasses or equivalent).	•Gloves •Long-sleeved gown •Filtering facepiece 3 (FFP3) or N99 mask/respirator (FFP2 or N95 if FFP3 not available)a •Eye and face protection (full-face shield/visor or polycarbonate safety glasses or equivalent). •Alternatively, powered air purifying respirators (PAPRs) with hoods may be used.28

^aThe European Standard (EN 149:2001) classifies FFP respirators into three classes: FFP1, FFP2, and FFP3 with corresponding minimum filtration efficiencies of 80%, 94%, and 99%. The US National Institute for Occupational Safety and Health (NIOSH) classifies particulate filtering facepiece respirators into nine categories based on their resistance to oil and their efficiency in filtering airborne particles. N indicates not resistant to oil; R is moderately resistant to oil; and P is strongly resistant to oil – ‘oil proof’. The letters N, R or P are followed by numerical designations 95, 99, or 100, which indicate the filter’s minimum filtration efficiency of 95%, 99%, and 99.97% of airborne particles (<0.3 microns).29, 30.
