Frequently Asked Questions
Clear, plain-English answers to the most common questions about respiratory protection and our onsite fit testing process.
How often is fit testing required?
Under OSHA 29 CFR 1910.134, fit testing must be conducted before an employee uses a respirator for the first time, and at least annually (every 12 months) thereafter.
Qualitative vs quantitative—when is each required?
Qualitative (pass/fail based on taste/smell) is typically acceptable for half-face negative pressure respirators like N95s. Quantitative (machine-measured) is required for full-face respirators or half-face masks used in highly hazardous environments.
Can employees have beards?
No. OSHA prohibits facial hair (even stubble) that comes between the sealing surface of the facepiece and the face. Employees wearing tight-fitting respirators must be clean-shaven.
What triggers an immediate retest?
A retest is required before the annual mark if the employee changes the make, model, style, or size of their respirator, or if they experience significant physical changes (weight loss/gain, dental changes, facial scarring) that could affect the seal.
Do we need medical evaluations before fit testing?
Yes. OSHA requires a medical evaluation by a Physician or Other Licensed Health Care Professional (PLHCP) before an employee can be fit tested or wear a respirator. We provide this digitally.
How long does a fit test take?
An individual qualitative or quantitative fit test typically takes about 10 to 15 minutes per employee, assuming they have already completed their medical evaluation.
What records do we need to keep?
Employers must maintain records of medical evaluations, fit test results (including the specific make/model of mask and the pass/fail or fit factor score), and proof of annual training.
What’s the difference between N95 and elastomeric/full-face testing?
N95s are disposable filtering facepieces, usually tested qualitatively. Elastomeric half-masks and full-face respirators are reusable and often require quantitative testing, especially if maximum protection factors are needed.
Can you test night shift / weekends?
Yes. We operate 24/7 and adapt to your shifts. If your team works overnight, we test overnight.
How do onsite group sessions work?
We deploy technicians to your facility with all necessary equipment. Employees book brief time slots to avoid production bottlenecks. We manage the testing, issue clearance cards, and provide you with a consolidated compliance report.
Are fit tests required for N95 masks?
Yes. Under OSHA 1910.134(f), filtering facepiece respirators (like N95s) are tight-fitting respirators and require annual fit testing, just like elastomeric half-masks or full-face respirators.
Who can perform a medical evaluation?
According to OSHA 1910.134(e)(2), medical evaluations must be administered by a Physician or Other Licensed Health Care Professional (PLHCP). Our online medical evaluations are reviewed by licensed professionals.
Is training required along with fit testing?
Yes. OSHA 1910.134(k) mandates that employers provide comprehensive, understandable training prior to requiring an employee to use a respirator, and at least annually thereafter. We provide required donning/doffing and seal check training during the fit test.
Can an employee test with their own mask?
Employees must be fit tested with the exact make, model, style, and size of respirator that they will actually use on the job, as specified in your written Respiratory Protection Program per OSHA 1910.134(f)(1).
Do we need a written Respiratory Protection Program?
Yes. If tight-fitting respirators are required in your workplace, OSHA 1910.134(c) requires the employer to develop and implement a written respiratory protection program with required worksite-specific procedures. As part of our service, we provide program design at no additional charge.
