Why do I need to do a face-fit test for my respirator and what does it involve?
|Protec Staff29/03/2007 10:45:01||It is very important that your respirator fit correctly if it is to offer the right level of protection - any leaks around the face piece will allow you to inhale contaminated air. There are two types of face fit test available. The first is by dust levels between the inside and outside of the face piece by means of a probe - This is very accurate but also very expensive. The most popular method is to place a hood over the wearers head and spray a bitter or sweet tasting solution via a nebuliser into this while the wearer breathes through the respirator. An ill-fitting face piece will allow the wearer to taste the bitter or sweet solution.|
