QUICK-FILL SYSTEM OPERATION

redundant seal.

TRANSFILLING BETWEEN SCBA FROM MSA 
(EMERGENCY BREATHING SYSTEM)

Note:

The SCBA with the higher pressure reading is the

donor. The SCBA with the lower pressure is the receiver.
Transfilling between users of SCBA should be performed
only during life-threatening emergencies or simulated
training exercises. Both donor and receiver must return to
fresh air immediately following the procedure.

Do not transfill if the donor's audible alarm is ringing
or NightFighter Heads-Up Display System/ ICM Unit
Gauge are flashing. Failure to follow this warning may
result in shorter escape time to return to fresh air,
causing serious personal injury or death.

The audible alarm begins ringing and NightFighter Heads-
Up Display System begins flashing to indicate that the
pressure in the cylinder has been reduced to 25% of its
rated working pressure. Remaining service time must be
used for escape to fresh air. If the donor's audible alarm
begins ringing or NightFighter Heads-Up Display/ICM Unit
Gauge begins flashing during transfilling, the donor should
disconnect and preserve his escape time.

1.  If the donor's alarm is not ringing or NightFighter

Heads-Up Display System/ICM Unit Gauge are not
flashing and you have sufficient air to transfill air to a
receiver, (greater than 1000psig for Low Pressure
SCBA and greater than 2000psig for High Pressure
SCBA), follow these steps.

a. Remove the 3 foot emergency transfill hose from its

protective pouch.

b. Remove the rubber dust cover from both female fit-

tings on the Quick-Fill System hose assembly.

c. Remove the rubber dust cover from the male Quick-

Fill System fitting.

d. Push the female fittings on to the male fittings until

they click in place. Pull on the hose to be sure it
snapped in place.

If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Failure to follow this warning may result in seri-
ous personal injury or death.

e. After approximately 30-60 seconds, pressure

between the SCBA cylinders will be equal.

f. Disconnect the Quick-Fill System hose from the

SCBA by pulling the gray sleeve back on both ends.
A hiss or pop may be heard as the fittings separate
and the high pressure air is sealed off.

g. Immediately install the dust cover on the Quick-Fill

System male fitting. The dust cover prevents dirt,
water, and debris from entering the fitting and acts
as a redundant seal.

QUICK-FILL SYSTEM EMERGENCY OPERATIONS

1.  If the dust cover will not stay on the male fitting

because air is leaking:

a. Immediately reconnect the Quick-Fill System hose

to seal off the leak and return to fresh air.

b. If you cannot reconnect the hose, reach behind and

close the cylinder valve. Air pressure in the regulator
will drop and the leak will slow down.

c. Quickly replace the protective dust cap on the male

fitting. This will form a redundant seal.

d. Open the cylinder valve and return to fresh air

immediately.

2.  Preparing the Quick-Fill System for Storage:

a. Press in on the center of the quick-disconnect dust

cap to release any pressure in the Quick-Fill System
hose.

b. Roll up the hose and place it in its protective pouch.

Note:

Only persons trained in MSA Maintenance are

authorized to repair or disassemble the Quick-Fill System.
If repairs are required, contact your nearest MSA office.
