Face fit testing 

If you use RPE in the workplace, then under current legislation they need to be face fit tested to ensure the wearer is fully protected. As part of the fit testing procedure training in the correct use of RPE is provided.  We have a number of different makes and models of RPE so that we can find the best fit for the end user. Remember every face is different and it’s not one size fits all.


Face Fit Testing is a method used for checking that a tight fitting face piece matches the person’s facial features and seals adequately to the wearer’s face. An inadequate fit will significantly reduce the protection provided to the wearer and increase their risk of developing respiratory diseases.


Safety Group consider the quantitative method of face fit testing to be superior to the qualitative method. Using the latest technology we can accurately determine, by way of fit factor, the improvement in air quality inside of the delegates RPE. The PortaCount (the equipment we use) works by measuring the concentration of microscopic Isopropyl particles in the ambient air and then measuring the concentration of those that leak into the respirator. A quantitative fit test is not affected by the person’s sense of smell, taste or sensitivity to irritant chemicals.

Qualitative fit testing is still considered an acceptable way of carrying out face fit testing. Wearing a hood the seal of the mask to the delegate’s face is tested by spraying in a bitrex solution. If the bitrex can be tasted then the mask does not fit, if the bitrex is not tasted then the mask is considered to fit adequately. The testing can be carried out by one of our trained technicians or we can train a member of your organisation to administer the test.
