Adjust the top strap to
a comfortable height.
Note – if you have a ponytail,
bun or hair accessories, make
sure they are not trapped
between the harness and your
head.
Settle your face into the mask
face seal. Gently tighten each
harness strap in turn, starting
with the bottom straps. As you
pull each strap, use your other
hand to steady the mask on
your face.
Continue to adjust the straps,
loosening and tightening as
necessary, until the mask face
seal presses evenly on your
face around its entire length.
If necessary, adjust the mask
up or down (using the top
strap) so that the inner mask
sits comfortably around your
nose.
CHECK THAT THE MASK SEAL DOES NOT CROSS YOUR HAIRLINE
Check all the way around the mask seal, paying particular attention to your forehead and temples. The seal
must not cross your hairline .
STEP 5 – SEAL CHECK
Carry out a negative pressure seal check
Using your index fingers or thumbs, cover the air inlets on
both air clips.
Breathe in sharply. You should not be able to draw any
air into the mask. The mask should be sucked in towards
your face as you inhale. Listen for squeaking or whistling
noises which indicate air is leaking past the seal.
Hold your breath for 10 seconds. The mask should stay
collapsed against your face. If the mask seal slowly
recovers (mask moves away from your face) there is a
leak. Readjust the mask fit and repeat the negative
pressure seal check.
Resume normal breathing and proceed to the next step.
WARNING
IF YOU CANNOT ADJUST THE MASK TO AVOID YOUR HAIRLINE, THE MASK IS NOT
SUITABLE FOR YOU AND MUST NOT BE WORN.
WARNING
IF A SATISFACTORY SEAL CHECK CANNOT BE ACHIEVED, DO NOT ENTER THE
CONTAMINATED ZONE.
