RPE Fit Testing is essential for workers required to wear RPE. IPM conduct quantitative respirator fit testing using a TSI PortaCount fit testing system. The TSI PortaCount utilises particle counting technology to accurately assess the fit factor of the respirator. It measures the concentration of particles both inside and outside the respirator while the wearer performs a series of exercises or movements. By comparing the particle concentration inside and outside the respirator, the PortaCount calculates a fit factor, which indicates the effectiveness of the seal and fit of the respirator.

The fit testing process will include evaluating the current respirators' effectiveness, measuring the fit factor, and providing guidance on proper donning and doffing procedures. In cases where the current respirators are inadequate, recommendations for respirator selection, adjustment, or replacement will be provided based on the fit testing results.

It is anticipated that each test will take approximately 30 minutes per person (longer if multiple respirators are tested to achieve the required fit factor), following which a certificate will be issued outlining the testing procedure, type of mask, and fit factor achieved.

Please note that all individuals undergoing respirator fit testing must have a clean-shaven face to ensure a proper fit and an adequate seal. Facial hair, such as beards, moustaches, or stubble, can interfere with the seal between the respirator and the face, compromising the effectiveness of the respiratory protection.
