Respiratory Fit Testing in BC and AB

A Fit Test is a test to measure the quality of seal between a person's clean shaven face and a respirator or mask (e.g. N95). It is required for many jobs in a wide variety of industries as they have to ensure that their employees are equipped with a tight fitting respirator. Due to Covid-19 many individuals who did not previously need a Respirator or Fit Test now require both.

IRWIN'S team of trained Occupational Health & Safety experts will answer any questions you have about the fit testing process, requirements to wear a facepiece respirator, what type of respirator is best for you, seal check and how to maintain it.

There are TWO major categories of fit tests: Qualitative (pass/fail basis) and Quantitative (scientific measure basis). Although IRWIN'S can perform both, we highly recommend the Quantitative test as it provides a much more accurate reading of the quality of the mask's seal.  

The only way to really be sure that your respirator fits is to have a respirator fit test done. Book your Fit Test N95 today, or call for help finding a local fit testing company in your area.

During health crises like the one we are currently in, the demand for masks skyrockets. People want to protect themselves and their loved ones, and understandably so. I’m sure you know that there are many different types of masks and respirators, and that they are not all the same. But are you using yours properly, and how can you be sure it really fits? Manufacturer instructions are generally very vague, and do not always spell out appropriate selection, use of, and care for your respirator. This brief program, which takes between 15 and 30 minutes, is built to educate you on how to properly select your respirator, how to put it on and take it off, what to watch for when you are wearing it, and how to properly care for it.

Quantitative Fit Testing

Book Now

This test is designed for tight fitting full-face masks but can also be used as a highly acute measure for half masks and N95 masks used by medical personnel. Quantitative fit-testing uses highly specialized equipment to measure particles in the atmosphere and inside the mask while the wearer performs tests to ensure a secure seal. Quantitative fit testing is performed using a Portacount machine, as per CSA standard, and is the only acceptable method for testing full face masks. It is proven to be more accurate than qualitative fit testing and therefore ensures the highest standard of safety. Quantitative Fit testing uses a highly accurate reading of the air particles inside and outside the mask. This method is recommended and provides the best possible reading of how well a mask fits your facial structure.

Qualitative Fit Testing

Book Now

Qualitative fit testing uses an odorous mist or irritant smoke sprayed in an enclosed hood. The participant wears a mask and tries to detect the material by smelling for it. If the test is a pass, no smell is detected. A qualitative test measures the PERSON'S ability to detect the odour through a mask. These tests, although not as accurate as a quantitative test, still accurately determine if a mask properly fits the wearer and are widely accepted in many industries. Testing of this kind is acceptable and limited to checking filtering face pieces and half-mask respirators.
Qualitative testing is fast, requires minimal equipment and are easily performed with large groups. Check with your employer to see if this an acceptable test process for your organization.
