Mask Fit Testing

Respirator Mask Fit Testing – Professional Drug and Alcohol Testing in Alberta

Quantitative mask fit testing acts as a highly accurate method to gauge the efficiency of a respirator mask’s seal, offering precise measurements crucial for optimal protection. We offer testing for half-masks, full-facepieces, CBRN/Gas masks, powered air-purifying respirators (PAPRs), and self-contained breathing apparatus (SCBAs). All tests are completed with our AccuFIT9000™ which conforms to CSA Z94.4 testing standards.

During a quantitative fit test, the individual wears the mask and connects to a measuring device that assesses particle concentration both inside and outside the mask. While engaging in a series of exercises, such as deep breathing or head movements, the machine calculates the leakage rate. This data is then utilized to determine the fit factor, offering a measurable evaluation of the mask’s effectiveness in preventing the entry of airborne particles.
