• The oxygen concentration is not known or is less than 19.5%.
• Contaminants or their concentrations are unknown or are known to be
immediately dangerous to life or health.
• Particulate concentrations exceed levels fixed by the applicable health
and safety regulations or protection factor 40 NPF whichever is lower.
• Gases and/or vapours are present except for respirators designated as
protecting against vapours, in which case vapour concentrations should
not exceed 20 NPF.
• The requirement for leak tightness is unlikely to be achieved if worn
against a beard or facial stubble.
• Do not wear standard eye glasses with a full-face respirator

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.
