DONNING
DONNING THE APR STRAP
The APR strap can be used in multiple configurations.
The canister can be configured to be set on the front of
the user (Configuration A) or to the back of the user
(Configuration B). Either configuration can be used
depending on whichever location is most comfortable and
appropriate for the environment in which the respirator is
being used. For most uses, the canister in the front
(Configuration A) will be used.
Note: If the clip needs to be used to secure the canister
in Configuration B, a buddy system may be necessary to
properly affix the alligator clip.
1. Disconnect the buckle keeping the two ends of the
breathing tube strap together.
2. Place both ends of the neck strap around the neck
and re-buckle.
3. Once the APR strap is buckled and in place, adjusts
the slides so that the breathing tube and canister are
against the body. When around the neck, tighten the
strap to keep the canister high on the back.
4. Ensure that breathing tube does not pull on the face-
piece when looking right, left, up and down. If the
facepiece is being pulled, adjust the straps and
breathing tube.
5. The alligator clip can be used to secure the canister to
the clothing while around the neck. In Configuration B
(on the back) a buddy system may be necessary. The
alligator clip should be pulled straight down towards
the belt and clipped so the breathing tube and canis-
ter are snug against the back.
Note: When properly donned in either configuration the
canister should be secure against the body, so the canis-
ter does not move and affect use of the respirator.
After the APR strap is adjusted, perform movements
that will be similar to those movements that will be
made during use. If any movements cause the breath-
ing tube to pull on the facepiece seal, readjust the
neck strap to allow for more breathing tube slack
between the facepiece connector and the tube attach-
ment point of the neck strap. There must be enough
slack in the breathing tube so that the breathing tube
does not cause a break in the facepiece seal during
use. If adjusting the neck strap does not relieve the
tension in the breathing tube, a longer length breath-
ing tube can be used. Failure to follow this warning
may result in serious personal injury or death.
Note: Use a buddy, if the situation permits, to ensure that
the APR is donned correctly (the head harness is in place,
the canister is positioned correctly, the neck strap is
secure, and all components are properly assembled and
tightened).
After the APR strap has been properly attached and
adjusted, a negative pressure seal test must be conduct-
ed to verify the facepiece seal.
NEGATIVE PRESSURE SEAL TEST
The negative pressure seal test must be performed each
time the facepiece is donned. A good face-to-facepiece
seal must be verified before entering a hazardous area.
Perform the test as follows:
1. Ensure respirator is assembled properly.
2. Block off canister inlet using the palm of the hand.
3. Inhale gently and hold breath for 10 seconds. If the
seal is good, the facepiece will collapse and remain
collapsed against face. Remove hand and breathe
normally.
4. Remove the regulator by pressing both buttons and
reattach.
5. Ensure proper engagement by pulling on the regulator
to verify that the regulator is securely attached to
facepiece.
6. If the facepiece did not remain collapsed during the
test, or any leakage is noticed, readjust straps and
perform negative pressure seal test again.
7. If this does not correct the leak, the facepiece will not
provide protection. If the leakage is from the face seal,
a different size mask may provide a good seal. If other
than face seal leakage is detected, the condition must
be corrected before performing another test.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see ANSI Z88.2). An improper facial
seal may allow contaminants to leak into the face-
piece, reducing or eliminating respiratory protection.
Do not use this device if such conditions exist. The
negative pressure seal test must be conducted and
passed before each use. Never remove the facepiece
except in a safe, non-hazardous, non-toxic atmos-
