Fit Testing Respirators

All respirators that rely on a mask-to-face seal must be fit tested to validate the seal is air-tight. This fit test must be performed:

  • Prior to first issue.
  • When there’s a change in the model, style or size of respirator used.
  • When there’s a physical facial change in the person wearing the mask.
  • At a minimum annually.

Guiding Regulation: (OSHA’s) Respiratory Protection Standard, 29 Code of Federal Regulation (CFR) 1910.134 Appendix A – Fit Testing Procedures (Mandatory)

There are two categories of Fit testing – Qualitive and Quantitive

  • Qualitative  – relating to, measuring, or measured by the quality of something rather than its quantity.
  • Quantitative – relating to, measuring, or measured by the quantity of something rather than its quality.  

We will review the requirements of each.
