Quantitative Fit Testing

We offer quantitative fit testing including training compliant to standard CSA Z94.4

We test most brands and makes of SCBA mask, half and full-face respirators.

A quantitative fit test involves a device called Respirator Fit Tester. A quantitative fit tester works by measuring the concentration of particles inside a mask or respirator as compared to the concentration outside of the mask.

This is done using a particle counter or other monitoring device. The fit tester then calculates a fit factor, which is a measure of how well the mask fits the wearer and how effective it is at filtering out particles. This fit factor is used to determine if the mask provides a proper seal and adequate protection for the wearer.

1. You will receive training on the mask you are being tested on, including how to properly don, seal check, and safely remove it. The technician will provide you with any necessary follow-up instructions or adjustments to your mask.

2. The participant must complete the exercises displayed on the monitor screen in the specified sequence. After each exercise, the Portacount® will determine and show a fit factor.
 

Failing to achieve the correct fit factor for any exercise will void the entire fit test. If this happens, the participant must try a different respirator or adjust the fit of the current one, redo the user seal checks, and repeat the fit test.

If at any point during the fit test you experience discomfort, please inform the technician immediately. Remember, the proper fit of your mask is crucial for your safety in hazardous environments.
