5 Storage
WARNING!
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 SCBA or spare cylinders within or near an area where the
SCBA can or might be exposed to any substances and ambient conditions
that will or might attack any part of the SCBA, causing the SCBA to not
perform as designed and approved.
• Prior to storing the SCBA in a jumpseat, ensure there is no interference
between the SCBA and the seat. Ensure the SCBA and cylinder can be
removed easily without damaging the components.
• Do not store the SCBA for extended periods with the batteries installed in
the electronic components (if available) if the SCBA is not intended for
service. If the SCBA is in service, ensure that the batteries in the
electronic components (if available) have an adequate charge.
• Do not store the SCBA with an empty or partially filled cylinder. Always
install a fully-charged cylinder so that the SCBA is ready for use.
• Ensure the entire SCBA is clean and dry.
• Ensure the SCBA harness and full face mask head harness adjustment
straps are fully extended. Place the complete SCBA in the storage case or
suitable storage location so it can be easily reached for emergency use.
• For prolonged storage of the SCBA, remove the batteries from all
electronic components (if available) and housings to prevent battery
corrosion. Store the units in a cool, dry place.
