Protect your team. Get a practical overview of proper techniques for fitting and ensuring respirator effectiveness in How To Fit Test Respirators.
Workers can use How To Fit Test Respirators to strengthen the knowledge and judgment needed on the job. Key outcomes include the ability to carry out respirator fit-testing procedures, check respirator seals and fit, and inspect and maintain respirator equipment. The material also helps learners carry out applicable expectations and recommended practices. Practical examples connect the subject to routine tasks, expected procedures, and decisions employees may need to make on the job. Learners finish with a clearer understanding of what to look for, how to respond, and when to raise a concern or seek additional guidance.
Respirator fit testing is required for every employee who must wear a tight-fitting respirator, from N95 filtering facepieces to half- and full-facepiece cartridge respirators. That includes workers exposed to dust, silica, fumes, mists, or chemical vapors. The 10-minute video, in English, guides safety staff and wearers through the process.
OSHA's respiratory protection standard, 29 CFR 1910.134(f), requires fit testing for tight-fitting respirators. Testing must be done before first use, whenever a different make, model, style, or size is used, and at least annually. Each test must follow an OSHA-accepted qualitative or quantitative protocol.
Qualitative fit testing is a pass/fail test that relies on the wearer detecting a test agent such as saccharin, Bitrex, or banana oil. Quantitative fit testing uses an instrument to measure leakage and produce a numerical fit factor. Qualitative tests are limited to respirators that need a fit factor of 100 or less.
A respirator fit test is a formal, periodic test confirming that a specific respirator model and size fits the wearer. A user seal check is a quick positive and negative pressure check the wearer performs every time the respirator is put on. A seal check never replaces a required fit test.
No, a tight-fitting respirator can't be worn with a beard or any facial hair that comes between the sealing surface and the face. OSHA's 29 CFR 1910.134 prohibits it because hair breaks the seal and lets contaminants leak in. Loose-fitting powered air-purifying respirators can be an option for bearded workers.
