Fit test for the right reason
09 December 2020
RESPIRATORS PROTECT workers from breathable hazards in the workplace. Even the best mask cannot protect the wearer if it leaks due to a poor fit, with facial characteristics or the wrong model mask selected being the major cause.

Businesses that have workers wearing respirators are required by HSE INDG 479 to perform respirator fit testing and confirm those respirators will provide the right level of on-the-job protection needed.
WHAT IS RESPIRATOR FIT TESTING?
Respirator fit testing is a key component of any respiratory protection programme that protects staff from airborne hazards. With the quantitative method (QNFT), an instrument provides users with data that accurately measures a respirator’s fit. Persons required wearing respirators on-the-job should be fit tested by accredited fit testing specialists to ensure respirators are providing maximum protection.
SIMPLIFY MASK SELECTION AND IMPROVE TRAINING
TSI says that the PortaCount Respirator Fit Tester works for any type or brand of a respirator. The instrument features intelligent touchscreen solutions, providing assistance across your entire respiratory protection programme from training through compliance. It takes real time measurements during movement, under real-world conditions to provide both staff and administrators with a greater understanding of how a respirator may or may not fit.
