The order matters and is frequently reversed. An employee must be medically evaluated and cleared before being fit tested or required to wear a respirator. Wearing a tight-fitting respirator adds breathing resistance and heat load; the evaluation exists to find the people for whom that is a genuine risk. Fit testing someone who has not been cleared produces a record that means nothing.
Appendix C of the standard is answered by the employee and goes to the PLHCP, not to you. You receive a written recommendation: cleared, cleared with restrictions, or not cleared, plus whether a follow-up is needed. You do not receive their answers, and you are not entitled to them. Employers occasionally push on this. The answer does not change.
Qualitative testing relies on whether the wearer can taste or smell a test agent - pass or fail, no number. Quantitative testing measures particle concentration inside and outside the facepiece and produces a fit factor. Half-mask respirators need a fit factor of at least 100; full facepiece, at least 500. We run quantitative because the number is auditable and because it tells you something when a fit is marginal rather than simply failed.
Any hair that crosses the sealing surface breaks the seal. That is not a company preference, it is physics, and no amount of adjustment compensates. A day or two of stubble is enough to fail a fit test. Tell crews before we arrive rather than on the morning, and where beards are worn for religious reasons, plan for a loose-fitting powered air-purifying respirator instead - that is a legitimate route and it needs ordering in advance.
Fit testing is annual, but a new test is required sooner if the employee changes respirator make, model or size, or if their face changes materially - significant weight change, dental work, or facial scarring. We flag these at the visit rather than waiting for the anniversary.
