What a Fit Test Pass Truly Entails
Now, the truth is that fit testing, especially when it comes to tight-fitting respiratory face pieces is something which has been used for quite a while now. However, there are yet quite a lot of widespread misconceptions as well as misunderstanding regardless what a fit test pass truly entails. Different aspects would usually generate research papers, and there are a few different ones which are dedicated to this issue. In any case, the below will attempt to explain certain key considerations and to describe its relevance to the proper control of exposure throughout the usage of protective respiratory devices.
Why Fit Testing?
The purpose of this particular respirator fit testing is actually designated to verify that the actual selected make as well as model and also the size of the face piece accommodates the facial characteristics of the individual perfectly. That’s the main purpose, and that’s what needs to be taken into account.
Passing the fit test, however, doesn’t really guarantee that every time the person dons the face piece the adequate fit is going to get achieved. In fact, it identifies that this particular face piece has the actual potential to fit the facial characteristics, provided the wearer makes the necessary adjustments on his own.
Things to Consider
In the United States, the NIOSH is responsible for the testing and the certification of the Respiratory Protective Device (RPD). Total Inward Leakage measurement (TIL), on the other hand, hasn’t been a part of the certification process at all. The actual evaluation of fit has relied on testing which is individual as well as different mandated by the OSHA checking procedures. However, understanding the complications that this could deliver, the NIOSH are already implementing TIL testing as part of the certification process which is designated to evaluate the performance of RPD under lab conditions.
