Respirator Training and Quantitative Fit Testing

Respirator Training and Quantitative Fit Testing (QNFT)The quantitative fit test measures the leakage of the challenge agent into the respirator without dependence on a worker’s response to it.  Respirators that require a fit factor above 100 must be fit tested using the quantitative (QNFT) test method.  We strongly encourage quantitative fit testing for all workers potentially exposed to asbestos, lead, arsenic, cadmium, mercury, silica, hexavalent chromium, mold, solvents and other toxic agents.

Workers that utilize air purifying respirators (APRs) must be trained in their proper use and have fit tests performed periodically.  IHR’s experienced staff will help you produce a written respiratory protection program for your site, select the proper APRs for the application, train your workers in the in the proper use of the APR, and perform quantitative fit testing (QNFT) of the individual workers.  Our services include QNFT for N95 respirators.

Our service is efficient, and the training and quantitative fit testing can be performed in less than 30 minutes.  We can perform this testing at your site, or at our offices in Boise.  IHR will maintain a record of the fit test (indefinitely), and re-train and re-test the workers periodically.  Our service would follow the required medical approval for the individual worker to use an APR, and this documentation must be in place before we can proceed with the fit testing.  We can assist you in acquiring this medical approval via a local health care provider, or on line with credible respirator manufacturers, e.g., 3M & North.
