Fitting your Full Face Mask
• Visually inspect the mask for any tears or damage, ensuring all
components is in place and secure.
• Connect filtering cartridges to face piece
• Fully extend all head straps prior use.
• Centre the face mask onto your face by placing your chin and nose in the
chin and nose cup simultaneously whilst placing the extended harness
over your head
• Adjust harness straps, by first pulling the neck straps, towards the shape
of your head followed by temple straps and head strap
• Never pull harness straps away from the shape of your head as harness
straps can result in damage, rendering mask un-usable.
• Once tighten securely, conduct negative and positive pressure seal checks
of the masks
Mask leak tests
Negative pressure:
- Cover inhalation filters with the palm of your hand, inhale and hold your
breath for 5 seconds.
- The facepiece will collapse and remain collapsed against the face.
- Remove hand and breathe normally.
- If the facepiece did not remain collapsed during the test, or any leakage is
noticed, readjust straps and perform Negative Pressure Seal Test again.
Positive pressure check:
- Place palm of your hand over the exhalation valve and exhale.
The face piece should not leak around the face seal
- Maintain positive pressure for at least 5 seconds
a) If no outward leakage is detected, the test has been passed.
b) If leakage is detected (usually felt as a cool sensation against the
skin or as a loss of pressure hold), either the respirator is
malfunctioning or a gross leak exists between the face and face
piece
Removal of your mask
- Push harness buckles forward to loosen and fully extend the
harness straps.
- Insert thumbs under the bottom harness strap to pull face mask up
and away from face.
