Leakage; Storing The Emergency Transfill Hose - MSA G1 SCBA Operating Manual

13.4 Leakage

WARNING!
During transfilling, if the dust cap will not stay on the male fitting because air is leaking, do the following
steps to correct the condition before using the SCBA.
Failure to obey this warning can result in serious injury or death.
(1) Immediately connect the Quick-Fill hose to seal off the leak, and return to fresh air.
(2) If the hose will not reconnect, reach behind and turn the handwheel clockwise to close the
cylinder valve. Air pressure in the regulator will decrease, and the leak will slow.
(3) Quickly install the protective rubber dust cap on the male inlet fitting on the UAC fitting to make
a redundant seal.
(4) Turn the handwheel counterclockwise to open the cylinder valve.
(5) Return to fresh air immediately.

13.5 Storing the Emergency Transfill Hose

Do the following to prepare the emergency transfill hose for storage:
(1) Push in on the center of the quick-disconnect dust cap to release any pressure in the emergency
transfill hose.
(2) Wind up the hose and put it in its protective pouch.
