Visual Inspection and Functional Checks
PremAire Cadet Escape G1
US
(7)
Inspect the intermediate pressure relief valve. Verify that the relief holes are clear and free of
debris or other contamination.
(8)
Inspect the valve assembly seal ring to verify that it is present and properly seated. Inspect the
seal ring for rubber deterioration, dirt, cracks, tears, holes, or tackiness.
(9)
Inspect the hose connections. Verify that the hoses are properly secured.
(10) Inspect the fill port. Verify that the fill port dust cap is present and properly secured.
It is also essential that the required inspections and tests be performed on all respirator cylinders in
accordance with Department of Transportation (DOT) regulations. DOT regulations require that
composite cylinders be retired from service after the fifteenth year. Please note this does not include
cylinder valve assembly which may be reused. Aluminum cylinder service life is indefinite if proper
inspection and hydrotest procedures are followed and they indicate that the cylinder may remain in
service. Contact an MSA distributor or sales associate for additional information regarding this policy.
NOTE: ANSI Z88.5 recommends checking cylinder pressure weekly. For maximum safety the cylin-
ders should be stored full or empty (pressure above ambient but less than 100 psig).
Carrier and Harness
(1)
Inspect all harness components for cuts, tears, abrasion or signs of heat or chemically-related
damage.
(2)
Inspect the cylinder carrier components for cuts, tears, abrasion or signs of heat or chemically-
related damage.
Verify that the carrier securely retains the cylinder.
Record Keeping
Following inspection, the date and initials of the designated inspector should be recorded on an
inspection tag. A more detailed record of the operations performed can be noted on an inspection and
maintenance log, available from MSA. When the inspection data has been recorded, the respirator is
ready for use.
WARNING
All repair and replacement of subassemblies must be carried out by an MSA certified repair techni-
cian. Failure to follow this warning will void NFPA and NIOSH certifications and can result in serious
injury or death.
