At the beginning, it was thought that the half-mask fit quite well to the worker's face, if during a fit test the protection factor (fit factor) is not less than 10 (later, experts began to use "safety factor" = 10 during the fit test; threshold fit factor become 10 × 10 = 100). The widespread use of fit testing in the industry gives ...
A qualitative fit test starts with an unfiltered/non-respirator sampling of the substance of choice to verify that the subject can detect it accurately. Substances include: Isoamyl acetate—This substance has the smell of bananas. It is used only for fit testing of elastomeric masks. [18]
The European respirator standards refer to the filtering classification by EN 149, EN 14683, and EN 143, all European standards of testing and marking requirements for respirators. [1] FFP standard masks (where FFP stands for filtering facepiece) [2] cover the nose, mouth and chin and may have inhalation and/or exhalation valves. [1]
For those who are collecting respiratory specimens from, caring for, or transporting COVID-19 patients without any aerosol-generating procedures, WHO recommends a surgical mask, goggles, or face shield, gown, and gloves. If an aerosol-generating procedure is performed, the surgical mask is replaced with an N95 or FFP2 respirator. [22]

An N95 respirator is a disposable filtering facepiece respirator or reusable elastomeric respirator filter that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84, effective July 10, 1995.
