from service. All other cylinders which are not 3AA type
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 avail-
able 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.
Appropriately connect the cylinder to the filling system
and refill. Terminate the filling when the pressure reaches
the maximum service pressure and allow the cylinder to
cool to room temperature. If necessary, top-off the cylin-
der 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 substances that will or might attack any part of the air
mask, causing 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.
REMOVING THE AIR MASK
37
DO NOT drop the cylinder or bump the valve knob. An
unsecured cylinder can become an airborne projectile
under its own pressure if the valve is opened even
slightly. Failure to follow this warning can result in
serious personal injury or death.
Do not store the air mask for extended periods with the
batteries installed in the electronic components if the air
mask is not intended for service. If the air mask is in ser-
vice, ensure that the batteries in the electronic compo-
nents have an adequate charge. Do not store the air mask
with an empty or partially 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 facepiece 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 batter-
ies from all electronic components to prevent battery cor-
rosion. Store the units in a cool, dry place.
