A fit test verifies if your mask or respirator is providing you the correct effective seal for protection in your industry. The test also establishes if you have the right size, make and model.


If you need a professional fit test in Northwest BC, you can count on Aquila Safety. There are 2 types of fit testing in Canada and Aquila Safety provides them.


  • Quantitative fit testing (QTFT) is the highest level of protection, and is a pass or fail determination to check the leakage from your respirator. Aquila Safety has a TSI machine is used to measure the amount of leakage into the facepiece. In this scenario, the respirator's facepiece is attached to a probe that is connected to the machine by a hose with aerosol or controlled negative pressure.

    Aquila Safety is the only local company in the area that offers Quantitative Testing. No other respirator fit tester can quantitatively fit test all types of respirators - gas masks, SCBAs, respirators, N95, P1 and P2 disposable (filtering-facepiece) respirators.

  • Qualitative fit testing (QLFT) is the process to measure the leakage from tight fitting facepieces or respirators. It involves spraying a bitter or sweet aerosol or an irritant smoke spray near your mask or respirator, and if you can taste the spray, your mask does not have a proper fit.
