FACESEAL CHECK
With the headtop head harness folded
over the visor of the facemask check for
a good faceseal.
Offer the facemask up to the face with
one hand
Close off the inlet port of the facemask
with the other hand
Inhale and check that the mask pulls
onto the face and remains in position
while you hold a breath
A good faceseal will be indicated by the
mask staying in place with the vacuum
created.
If the mask does not stay in position then
this indicates a possibility of, but is not
limited to either of the following;
Incorrect fitting
Incorrect mask size
Faulty exhalation valve
Defective/damaged mask seal.
If you are happy with the fitting of the
mask and you can find no apparent
defect then it may be necessary to
change mask size and repeat.
If there is a fault with the mask then do
not use until the fault has been found
and rectified.
Note: The mask should feel firm against
the face with no undue movement.
Excessive tightening will cause
discomfort and may distort the faceseal.
Do not use a mask if you cannot achieve
a comfortable fit.
