What is quantitative respirator fit testing?

Quantitative fit testing uses a machine to introduce a challenge solution into the hood while the person’s mask is on. The particle concentration outside the respirator is measured against the concentration inside the respirator. The ratio of these two numbers is the fit factor, and if the fit factor is below OSHA’s acceptable limit, the person is cleared to wear that mask.

Which respirators require quantitative fit testing?

Quantitative fit testing must be used for all full-face masks, and can be used to test any half-face mask, including:

  • Elastomeric full facepiece respirator
  • ASR: atmosphere supplying respirators
  • SAR: supplied-air respirators
  • SCBA: self-contained breathing apparatus
  • Combination SAR/SCBA respirators
  • APR: air-purifying respirators
  • FFR: filtering facepiece respirator
  • EHMR: elastomeric half mask respirator
  • PFR: particulate filtering respirators
  • N (not resistant to oil) 95,99,100
  • R (somewhat resistant to oil) 95,99,100
  • P (strongly resistant to oil) 95,99,100
  • HEPA (high efficiency particulate air)
