REMOVING THE AIR MASK
5. To check that the cylinder is secure, place one hand
on the back plate and grasp the cylinder valve with
the other. Try to pull the cylinder and valve down and
out away from the carrier. Make sure that the strap
and buckle hold the cylinder securely in the carrier.
N
OTE:
I
f the cylinder feels loose, re-check that the strap
a
nd buckle are properly adjusted. Open cylinder buckle.
T
ighten cylinder strap by pulling on top (outer) strap. It will
be necessary to reposition the black plastic slide during
adjustment. Tighten cylinder strap until cylinder buckle is
approximately 45 degrees from vertical. Close the cylinder
buckle. Do not use the air mask if the cylinder is not held
securely in the carrier.
DO NOT over-tighten the cylinder
strap; otherwise it will damage the center buckle
assembly.
6. Check that the O-ring is inside the Alarm with URC
Assembly coupling nut. If the O-ring is damaged it
must be replaced before the alarm is used.
7. Thread the alarm with URC Assembly coupling nut to
the cylinder valve and hand-tighten (no tools).
CHARGING CYLINDERS
A lightweight SCBA cylinder can become airborne solely
under the thrust of air from an inadvertedly opened cylin-
der valve. If a cylinder is removed from a horizontal shelf
by grasping the handwheel, the weight of the cylinder can
cause the cylinder to rotate downward causing the valve
to open slightly.
• Never carry a cylinder by the handwheel.
• Avoid dropping the cylinder or bumping the hand-
wheel.
• Use the handwheel only to open and close the
cylinder valve.
A valve could partially open causing the cylinder to
become an airbor
ne projectile under its own pressure
and result in serious personal injury or death.
1. Remove from service if cylinder shows evidence of
exposure to high heat or flame: e.g., paint turned
to a brown or black color, decals charred or miss-
ing, gauge lens melted, or elastomeric materials
distor
ted.
2. Use this device only after receiving proper training
in its use. Use in accordance with this label and
MSA apparatus instructions.
3.
T
o maintain NIOSH appr
oval, container must be
fully charged with respirable air meeting the
requirements of the Compressed Gas Association
specification G-7.1 1989 for Quality Verification
Level (grade) D air or equivalent specification.
4. Do not use unless the cylinder is filled to the full
pressure approved.
5. Do not alter, modify, or substitute any components
without approval of the manufacturer.
6. Inspect frequently. Maintain according to manufac-
t
urer’s instructions. Repair only by properly trained
p
ersonnel.
Failure to follow these warnings can result in serious
personal injury or death.
SAFETY PRECAUTIONS FOR MSA SELF-CONTAINED
BREATHING APPARATUS CYLINDERS
Breathing apparatus cylinders should be fully recharged
as soon as possible after use.
Cylinders should not be stored partially charged for two
reasons:
1. If used partially charged, the duration of the apparatus
is reduced.
2. The pressure relief device is only designed to protect
a fully charged cylinder from the effects of a fire.
For maximum safety, the cylinders should be stored full or
at a pressure above ambient but less than 100psig.
Prior to recharging, cylinders must be examined externally
for evidence of high heat exposure, corrosion, or other
evidence of significant damage.
Additional information of value when performing external
and internal inspections of cylinders may be found in the
latest editions of CGA Publication C-6: "Standards for
Visual Inspection of Steel Compressed Gas Cylinders",
CGA Publication C-6.1: "Standards for Visual Inspection
of High Pr
essure Aluminum Compressed Gas Cylinders",
and/or CGA Publication C-6.2: "Guidelines for Visual
Inspection and Requalification of Fiber Reinforced High
Pressure Cylinders" available form the Compressed Gas
Association, Inc., 1725 Jefferson Davis Highway, Suite
1004, Arlington, VA 22202-4102.
If ther
e is any doubt about the suitability of the cylinder
for recharge, it should be returned to a certified hydrostat-
ic test facility for expert examination and testing.
Always check to be sure the r
etest date is within the pr
e
-
scribed period and that the cylinder is properly labeled to
indicate its gaseous service. New labels are restricted
items which ar
e not available except thr
ough cer
tified
hydrostatic test facilities.
When r
eplacing cylinder valves or after the r
etesting of
cylinders, make sure the proper cylinder valve, burst disc,
and O-ring ar
e installed prior to cylinder r
echar
ging.
Establish the ser
vice pr
essur
e of the cylinder
. Type 3 AA
(steel) cylinders that bear a plus (+) sign after the latest
r
etest date may be r
echar
ged to a pr
essur
e, i.e. a cylinder
stamped 3AA2015 with a plus (+) sign after the test date
