Quantitative Fit Testing (QNFT)Quantitative respiratory fit testing uses an instrument to measure the effectiveness of the respirator seal that is suitable for use on all air purifying, air supplying and N, R and P series filtering face piece respirators. This method does not rely on your sense of taste, smell, or irritation in order to detect the leakage. Instead, the respirator fit testing equipment measures real-time fit while the user simultaneously performs a series of moving, breathing and talking exercises designed to simulate the same movements made in the field.
Our respiratory fit test technicians will also address the proper donning and doffing of the respirator, how to perform seal checks, the care, use and maintenance of the respirator, the defining differences between N, R, and P-Series respirators, as well as half and full face piece respirators. Every participant who successfully completes the fit test is provided with a wallet card indicating the respirator they were fitted with and its size. Their employer will receive a record of training in the form of a fit test report that they can use for record keeping purposes.
