Everything You Need. Nothing You Don't.

Onsite Fit Testing provides end-to-end respiratory protection compliance under OSHA standard 29 CFR 1910.134. Our certified technicians travel to your facility and perform both qualitative (QLFT) and quantitative (QNFT) respirator fit testing using OSHA-accepted protocols. Before any employee is fit tested, we manage the required medical evaluation through a fully online questionnaire available 24/7, reviewed by a licensed healthcare professional. Beyond testing, we draft your written respiratory protection program (RPP) at no additional cost, manage electronic fit testing records with automated annual expiration reminders, provide fit test cards in both physical and digital wallet formats, and offer Powered Air-Purifying Respirator (PAPR) training for employees who cannot achieve an adequate seal with a negative-pressure respirator.

Onsite respirator fit testing is a service where certified technicians travel to your workplace to verify that each employee's respirator forms a proper seal against their face. OSHA standard 29 CFR 1910.134 requires fit testing before an employee uses a tight-fitting respirator, whenever a different size or model is used, and at least annually thereafter. Onsite testing eliminates the need to send employees offsite, reducing downtime and simplifying logistics.

Qualitative fit testing (QLFT) is a pass/fail method that relies on the wearer's ability to detect a taste or smell — such as saccharin or Bitrex — while wearing the respirator. Quantitative fit testing (QNFT) uses an instrument to measure the actual amount of leakage into the facepiece and produces a numerical fit factor. OSHA accepts both methods under 29 CFR 1910.134 Appendix A. Quantitative testing is required for full-face respirators, while half-mask respirators can use either method.

OSHA requires respirator fit testing at least once every 12 months under 29 CFR 1910.134(f)(2). Additional fit testing is required when an employee switches to a different respirator model, size, or style, or when physical changes — such as significant weight change, dental work, or facial scarring — could affect the respirator seal.

Yes. OSHA 29 CFR 1910.134(e) requires a medical evaluation before an employee is fit tested or uses a respirator in the workplace. The evaluation is typically completed through a confidential questionnaire reviewed by a licensed healthcare professional, who then provides a written recommendation for each employee. Onsite Fit Testing offers a fully online medical evaluation process available 24/7.

A written respiratory protection program (RPP) is a document required by OSHA 29 CFR 1910.134(c) for any employer whose workers use respirators. The program must cover procedures for respirator selection, medical evaluations, fit testing, proper use, maintenance, and training. Onsite Fit Testing drafts this document at no additional charge for clients.

Onsite Fit Testing regularly handles groups ranging from 5 employees to over 500 in a single day, depending on the type of testing and the number of respirator models involved. For larger organizations with thousands of employees, multi-day scheduling is coordinated to minimize operational disruption.

Any industry where employees wear tight-fitting respirators must comply with OSHA's fit testing requirements. Common industries include healthcare, construction, manufacturing, auto body and paint shops, fire and emergency services, government agencies, pest control, warehousing, long-term care facilities, and maintenance operations.

Yes. OSHA requires employers to maintain fit testing records that include the employee's name, the type of fit test performed, the specific respirator model and size, and the date of the test. Onsite Fit Testing provides electronic records, automated expiration reminders, and physical wallet-sized fit test cards as well as digital passes for Apple Wallet and Google Wallet.
