levels of organic vapours (i.e. levels below the WEL).
• Use only in adequately ventilated areas containing sufficient
oxygen to support life.
• Do not use when concentrations of contaminants are immediately
dangerous to life or health.
• Leave the area immediately if:
* breathing becomes difficult
* dizziness or other distress occurs
• Discard and replace respirator if it becomes damaged, breathing
resistance becomes excessive, or at the end of one shift.

Correct use
The respirator may be used in concentrations of solid, water based
and non-volatile liquid based aerosols up to 10 times the Workplace
Exposure Limit (WEL). Assigned Protection Factor= 10.
It can also be used to protect the wearer against Ozone gas
generated in welding applications in concentrations up to 10 times
the WEL and provide relief from nuisance levels (concentration
below the WEL) of organic vapours.

2. Place the top elastic strap
around the head, above the
ears. Untwist the strap.
1. Thread top elastic strap through
top buckles. Repeat for bottom
strap and buckles. Place the
bottom elastic strap around the
head just below the ears. Untwist
the strap.
3. Adjust tension by pulling tabs of
each strap, as shown.
4. Using both hands, mould
metal nosepiece
comfortably to shape of
nose.
5. Strap tension may be
decreased without removing
respirator from the head by
pushing out on the back of the
buckles. If you cannot achieve a
proper fit do not enter
contaminated area. See your
supervisor.
6. The seal of respirator on the
face should be fit-checked prior
to wearing in the work area.
a) Cover the front of the respirator
with both hands, being careful not
to disturb the position of
respirator.
b) Inhale sharply. A negative
pressure should be felt inside
respirator. If any leakage is
detected, adjust position of
respirator and/or tension of strap.
Retest the seal. Repeat the
procedure until the respirator is
sealed properly.
