Respirator Fit Testing
Quantitative fit testing — done for you, or set up in-house.
OHD QuantiFit controlled-negative-pressure and AeroFit particle-count testing, with protocols for N95s through full-face respirators and OSHA 29 CFR 1910.134 records on every test.
- Quantitative (CNP & particle count)
- All respirator types
- OSHA 29 CFR 1910.134 records
Two ways to get compliant
We test on-site
Most popularOur technician brings calibrated OHD equipment to your facility and fit-tests your crew during the shift — every respirator wearer, documented and done.
- ✓ Quantitative, defensible results
- ✓ During-shift testing, no travel
- ✓ OSHA 1910.134 records delivered
You run it in-house
Buy the QuantiFit 2 or AeroFit, and we deliver, install, and train your team so you can fit-test on your own schedule.
- ✓ OHD QuantiFit 2 (controlled negative pressure)
- ✓ OHD AeroFit (particle counting)
- ✓ Install + hands-on operator training
The equipment we test with — and sell
The same OHD systems our technicians carry are available for your program, with install, training, and ongoing service from Foster.
Common questions
Quantitative vs. qualitative — which do I need?
Quantitative fit testing measures actual leakage and produces a numeric fit factor, which is defensible in an audit and required for certain respirators and protection factors. Both OHD systems we use and sell are quantitative.
Which respirators can you test?
All types — from N95 filtering facepieces through half-face and full-face respirators. Protocols follow OSHA 29 CFR 1910.134 Appendix A.
How often is fit testing required?
OSHA 29 CFR 1910.134 requires fit testing before first use, at least annually after that, and whenever the respirator model or the employee's face changes (weight change, dental work, scarring).
What records do we get?
A fit-test record for every employee — respirator make/model/size, protocol, pass/fail with fit factor, and test date — organized for your OSHA file.
Every respirator wearer, fit-tested and filed.
