Fit test in US Navy. The effectiveness of various types of respirators was measured in laboratories and in the workplace. [3] These measurements showed that in practice, the effectiveness of negative pressure tight fitting respiratory protective devices (RPD) depends on leakage between mask and face, rather than the filters/canisters. [4]
Loose-fitting PAPRs can be useful when a fit test for a tight-fitting respirator cannot be successfully passed, for example when facial hair is present. [2] [3] Masks may be reusable or disposable. Some masks allow the full face to be seen by others, aiding in interpersonal communication. [1]
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 ...

NIOSH air filtration ratings do not test the fit of a respirator. Fit testing is required by OSHA for employers when a hazard is present, and voluntary respirator use under Appendix D is not allowed due to the hazard. [30] Rules for fit testing are also defined by ANSI Z88.2. Z88.2 notes that, in Canada, respirator care and fit testing are ...
Other problems include using a size other than the size the wearer was fit-tested on, using the wrong sort of cartridge, re-using a cartridge that is no longer good, not doing a positive- and negative-pressure seal check each time the mask is donned, failing to test the respirator (and perhaps inhaling the carbon from a broken cartridge), and ...
