In this editorial we will try to understand various aspects of Face Fit Testing and why it is necessary and what are its implications. We will also explore various know hows of face adaptive testing.
What exactly it is?
The method of verifying whether a face piece which is tightly fitted matches a person's facial features and sits perfectly to the face of the wearer is named Face Fit Testing. This helps in eliminating the ones which do not fit well to the face.
Why is Face fit Testing so important?
The actual performance of a face fit depends on the way it fits between the face and the face parts. Every single person face vary in shape and seizes, hence it is important face seals perfectly, in order to prevent any kind of exposure. An inadequate fit will basically put the wearer in many risks. This might be a serious concern for the long term health of the person. Before it is used for D-event a pre-use of the face fit is an absolute mandate. This will mitigate the risk to nil. However, an ideal fit does not necessary mean that a day to day fit check should be skipped. A day to day seal check should be there no matter how ideal the shape is. The prominent types of face pieces are filtered, full mask and half mask.
What about face pieces which are loose fitting?
Face Fit Testing not necessary for loose ones. The reason being it's no issue with air flow. However every loose fit must be of right size to make sure that the wearer has no possibility of exposure of any kind. These are mostly prescribed for people wearing specs & those who have facial hair in the areas of the face seal. Loose fitting is a nice alternative to the tight ones for those who don't feel comfortable & are claustrophobic.
Scenarios in which a repeat check is necessary:
