Safety Precautions For Msa Self-Contained Breath- Ing Apparatus Cylinders - MSA FireHawk M7XT Fonctionnement/Entretien

5. DO NOT alter, modify, or substitute any components
without approval of the manufacturer.
6. Inspect frequently. Maintain according to manufactur-
er's instructions. Repair only by properly trained person-
nel.
Misuse can result in serious injury or death.
SAFETY PRECAUTIONS FOR MSA SELF-CONTAINED BREATH-
ING APPARATUS CYLINDERS
Breathing apparatus cylinders should be fully recharged as
soon as possible after use.
Cylinders should not be stored partially charged:
1. If used partially charged, the duration of the air mask 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 100 psi.
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-6.1: "Standards for Visual
Inspection of High Pressure 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 there is any doubt about the suitability of the cylinder for
recharge, it should be returned to a certified hydrostatic test
facility for expert examination and testing.
Always check to be sure the retest date is within the pre-
scribed period and that the cylinder is properly labeled to
indicate its gaseous service. New labels are restricted items
which are not available except through certified hydrostatic
test facilities.
When replacing cylinder valves or after the retesting of cylin-
ders, make sure the proper cylinder valve, burst disc, and o-
ring are installed prior to cylinder recharging. Determine the
maximum service pressure of the cylinder. All cylinders shall
be filled to the designated service pressure only (as found on
the DOT approval or stamping). For cylinders manufactured
under a U.S. DOT exemption (i.e., DOT-E-#####), the exemption
should be consulted and is available from the Associate
Administrator for Hazardous Materials Safety, Research and
Special Programs Administration, U.S. Department of
Transportation, 400 7th Street, SW, Washington, D.C. 20590-
0001.

REMOVING THE AIR MASK
Appropriately connect the cylinder to the filling system and
refill. Terminate the filling when the pressure reaches the maxi-
mum service pressure and allow the cylinder to cool to room
temperature. If necessary, top-off the cylinder such that the
service pressure is attained with the cylinder at a temperature
of 70°F. Close the valves on the cylinder and the filling system
and remove the cylinder. Apply a leak solution to determine if
there is any leakage between the cylinder and the valve. If
there is no leakage, the cylinder is ready for use.
STORAGE
Do not store the air mask or spare cylinders within or near an
area where the air mask can or might be exposed to any sub-
stances that will or might attack any part of the air mask, caus-
ing the air mask to not perform as designed and approved.
Prior to storing the air mask in a jumpseat, ensure there is no
interference between the air mask and the seat.
DO NOT drop the cylinder or bump the valve knob. An unse-
cured cylinder can become an airborne projectile under its
own pressure if the valve is opened even slightly. Misuse can
result in serious injury or death.
Do not store the air mask for extended periods with the bat-
teries installed in the electronic components if the air mask is
not intended for service. If the air mask is in service, ensure
that the batteries in the electronic components have an ade-
quate charge. Do not store the air mask with an empty or par-
tially filled cylinder. Always install a fully-charged cylinder so
that the air mask is ready for use. Complete Inspection and
Cleaning and Disinfecting Procedures outlined in this manual.
Ensure the entire air mask is clean and dry. Ensure the face-
piece head harness adjustment straps are fully extended. Place
the complete air mask in the storage case or suitable storage
location so it can be easily reached for emergency use.
For prolonged storage of the air mask, remove the batteries
from all electronic components to prevent battery corrosion.
Store the units in a cool, dry place.
NOTE: Fresh batteries must be installed in the FireHawk M7
HUD or I-HUD, FireHawk M7XT Power Module prior to storage
of the Air Mask at cold temperature for an extended period of
time.
