Respiratory Fit Testing

We’re proud to be Canada’s leader in respiratory fit testing. It’s a position we take seriously.

Any person who is required to wear a tight fitting face piece during the course of their normal day to day work duties, or any person who is required to wear a tight fitting face piece for emergency response activities should be fit tested to ensure an effective seal.

Both qualitative (QLFT) and quantitative (QNFT) respirator fit testing protocols are CSA approved, however given the stakes and superior results, we highly recommend QNFT.

At Levitt-Safety we mobilize as many fit test technicians as required to ensure the greatest number of fit tests in a set time period so to limit the disruption to the productivity of your operations.

No other Respiratory Fit Testing provider in Canada can deploy up to 12 respiratory fit test systems and generate the daily throughput that we can deliver. Our proven system of testing can complete sixteen N95 fit tests per hour, per technician (120 per 7.5 hour work shift) which can result in the lowest per head cost for our customers while maintaining compliance requirements and minimizing disruption to the work environment.

We normally fit test during the hours of 8 am to 5 pm, but our technicians are happy to adjust to your schedule and have completed evening and weekend sessions in the past to accommodate all workers. Flexibility is key when deploying our techs to meet the needs of our client.

Quantitative Fit Testing (QNFT)

Quantitative respiratory fit testing uses an instrument to measure the effect of the respirator seal that is suitable for use on all air purifying, air supplying and N, R and P series filtering facepiece 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.

Qualitative Fit Testing (QFLT)

Qualitative fit testing is a pass/fail test method that uses your sense of taste or smell, or your reaction to an irritant chemical to detect leakage into the respirator face piece. Qualitative fit testing does not measure the actual fit of the respirator. Whether the respirator passes or fails the test is based simply on subjective detection of the challenge agent into your face piece. There are four qualitative fit test methods accepted by CSA Z94.4:

  • Isoamyl acetate, which smells like bananas;
  • Saccharin, which leaves a sweet taste in your mouth;
  • Bitrex, which leaves a bitter taste in your mouth; and
  • Irritant smoke, which can cause coughing
