USE OF THE RESPIRATOR
The following information provides the basic steps for use of the AIR-
PAK SCBA. Training and practice with the equipment are required before
use to assure that the user is completely familiar with the operation of
the respirator.
The AIR-PAK SCBA must be worn over protective garments such as fire
fighting turnout gear, but may be worn under encapsulating protective
garments such as hazardous material (haz-mat) suits. determine what
other protective gear will be used and don the SCBA and the facepiece
accordingly.
The AV-3000 HT Facepiece is made of heat resistant materials. When using
the AV-3000 HT Facepiece in applications where high heat may occur,
follow all training and operating procedures relating to heat exposure. To
avoid possible injury, the respirator user must understand the hazards
of heat exposure including temperature, duration and repeat exposure.
If respirator use is expected at temperatures near or below freezing, or
if respirator is to be used after being kept at temperatures near or below
freezing, refer to LOW TEmPERATuRE OPERATIOn Section for additional
information and supplemental procedures.
DONNING AND PREPARATION FOR USE
1. Always check the cylinder gauge for a "FuLL" indication. If the cylinder
is not full, replace the cylinder before use. A gauge indication of other
than full may indicate an air leak in the cylinder and valve assembly
or a malfunction of the gauge assembly.
2. Always verify that the cylinder is held securely by the cylinder retention
assembly.
3. If a wall storage bracket is used, follow the instructions of the bracket
manufacturer for placing arms through shoulder straps and freeing the
respirator from the bracket.
4. If the respirator is stored in a hard or soft storage case, place the case
on the ground or level surface and open the case. Secure the regulator
in the regulator holder. Proceed as shown in FIguRES* 9-A thru 9-F.
a) Adjust the shoulder straps to their full outward (fully loose) position.
b) Spread shoulder straps and fold open waist pad. Stand the respira-
tor on the cylinder valve with cylinder toward you and the shoulder
straps away from you.
