If It Doesn’t Fit, It Doesn’t Protect.
A respirator is only as effective as its fit. As part of GMG EnviroSafe’s Respiratory Protection Program, our Qualitative and Quantitative Fit Testing services ensure that your employees’ respirators provide a proper seal, perform as intended, and meet OSHA 1910.134 compliance. Whether you're outfitting workers with N95s, half-face, or full-face respirators, GMG provides on-site, professional fit testing to verify protection, before exposure happens.
What's Included
Bilingual Training, Built for the Real World
GMG’s fit testing services are delivered at your location and structured to meet all OSHA 1910.134 requirements. Each element of the process ensures employees are properly protected, trained, and documented.
Medical Clearance Review
We verify that each employee has completed OSHA-required medical clearance before testing begins.
Qualitative Fit Testing (QLFT)
We conduct pass/fail tests using agents like Bitrex or saccharin for N95s and half-masks in low-exposure environments.
Quantitative Fit Testing (QNFT)
We use specialty instruments to measure exact leakage into the respirator, required for full-face and high-risk applications.
Respirator Selection Confirmation
We verify each employee’s respirator model, size, and style to match their role and facial characteristics.
Donning & Seal Check Training
We provide hands-on guidance to ensure employees can properly don their respirator and perform seal checks each time.
Documentation & Fit Test Records
We issue detailed records of all tests, including model numbers and results, for OSHA compliance and internal use.
Annual Reminders & Retesting
We offer optional reminders and scheduling support to keep your team compliant with annual testing requirements.
Who Is This Service For
Required for Any Employee Who Wears a Tight-Fitting Respirator
This service is essential for employees in construction, manufacturing, auto body, welding, healthcare, hazardous materials handling, and other environments where respirators are required. OSHA mandates that all tight-fitting respirator users be fit tested before use and at least annually. GMG delivers both qualitative and quantitative fit testing at your location, customized to your equipment and workforce.

Why It Matters
Compliance Isn’t Optional, And Fit Isn’t Guesswork
Respirators that don’t seal correctly can allow dangerous contaminants to enter the breathing zone, putting workers at serious risk. Improper fit is one of the top causes of respiratory protection failure, and one of the most cited OSHA violations. Fit testing confirms the right model, size, and fit for each individual. GMG helps you meet the regulation and protect your team with precise, efficient testing that fits your operation.

Respirator Fit Testing Requirements and Process
Answers to common questions about fit testing methods, OSHA requirements, medical clearance, and how GMG helps keep your team safe, sealed, and compliant.
Qualitative testing is a pass/fail method using taste or smell to detect leaks. Quantitative testing uses a machine to measure actual leakage and assign a numerical fit factor.
Any employee who wears a tight-fitting respirator, such as N95, half-face, or full-face respirators, must be fit tested before use and at least annually.
Yes. OSHA requires a medical evaluation to confirm the employee is physically able to wear a respirator before any fit testing is performed.
Typically 10–20 minutes per employee, depending on the type of test and number of respirators tested.
Yes. We offer both qualitative (Bitrex/saccharin) and quantitative (instrumented) testing, depending on your equipment and risk level.
We help identify a different size or model that fits properly and retest immediately if possible.
Yes. Each employee receives a signed fit test record, and your organization receives a log of all tested individuals.
We test all tight-fitting respirators, including N95s, elastomeric half-face, full-face respirators, and PAPRs with tight-fitting facepieces.
