Quick-Fill System Operation - MSA FireHawk M7 Responder Operation And Instructions Manual

QUICK-FILL SYSTEM OPERATION

The Quick-Fill System may be used for transfill operations
as described in this manual. Only qualified, trained per-
sonal Standard Operating Procedures should be devel-
oped for use of the Quick-Fill System.
PRECAUTIONS FOR USING QUICK-FILL SYSTEM
1. The Quick-Fill System can only be used to fill
approved air mask cylinders.
2. The Quick-Fill System is not to be used as a "Buddy
Breather" such that two users are sharing the air sup-
plied by one air mask cylinder simultaneously doing so
will void NIOSH approval.
3. The user is responsible for the air supply, which must
meet the requirements of Compressed Gas
Association Specification ANSI/G-7.1, Quality
Verification Level (Grade) D Gaseous Air or better, with
a moisture dew point of not greater than -65°F
(24ppm water vapor, normal). Pressures at the inlet of
the quick-fill hose must not exceed that of the air
mask (2216 psi or 4500 psi).
4. Using the 3000 psi URC Assembly to fill cylinders, the
cylinder can only be filled to 2216 psi. If the pressure
exceeds 2216 psi a relief valve in the URC Assembly
will vent at approximately 2525 psi or as low as 2400
psi. A 3000 psi cylinder can only be filled to 3000 psi
by using a secondary air supply; the 3000 psi URC
Assembly cannot be used for filling a 3000 psi cylin-
der.
5. The user also is responsible for connecting the quick-
fill hose to an appropriate secondary air supply.
6. The cylinder must be inspected for damage before
charging.
7. If filling cylinders in fresh air using the Quick-Fill
System topping off the cylinder is recommended after
the cylinder has cooled from initial fill. Topping off a
cylinder after it has cooled will ensure proper service
time.
• DO NOT use a 3000 psi air mask with a 2216 psi air
mask cylinder.
• DO NOT install a Quick-Fill System on a 3000 psi
air mask. This combination will not allow the relief
valve in the 3000 psi URC Assembly to open as
designed.
• DO NOT use the Quick-Fill System as a "Buddy
Breather" such that two users are sharing the air
supplied by one approved air mask cylinder simul-
taneously; doing so will void NIOSH approval.
• DO NOT transfill (be a donor) using a 3000 psi URC
Assembly. The 3000 psi URC Assembly has a
check valve that does not allow cylinders to trans-
fill (be a donor).
• Using the 3000 psi URC Assembly to fill cylinders,
QUICK-FILL SYSTEM OPERATION
the cylinder can only be filled to 2216 psi. If the
pressure exceeds 2216 psi a relief valve in the URC
Assembly will vent at approximately 2525 psi or as
low as 2400 psi. A 3000 psi cylinder can only be
filled to 3000 psi by using a secondary air supply;
the 3000 psi URC Assembly can not be used for
filling a 3000 psi cylinder.
• DO NOT lubricate the quick-fill fittings.
• DO NOT permit oil, grease, or other contaminants
to come in contact with the quick-fill fittings.
• The quick-fill hose assemblies and fittings are
designed to be used with Quality Verification Level
(Grade) D or better air as defined by ANSI/CGA G-
7.1.TRANSFILLING AIR FROM A SECONDARY AIR
SUPPLY.
Failure to follow the above warnings can result in seri-
ous personal injury or death.
The Quick-Fill System must be used only by qualified,
trained personnel who have carefully read and understood
these instructions, cautions, and warnings. NIOSH
approvals of SCBA from MSA are maintained while trans-
filling air ONLY if appropriate quick-fill hose assemblies
from MSA are used. Quick-fill hose assemblies and fit-
tings are rated for a maximum working pressure of 4500
psi.
NIOSH approval is maintained only when using the follow-
ing hose assemblies: 485331, 802687, 802688, 802689,
802690, and 48332, for filling cylinders in IDLH atmos-
pheres.
DO NOT use any transfilling hose assembly or fittings
other than those supplied by MSA specifically for the
URC Assembly for filling operations. Failure to follow
this warning will void NIOSH approval and can result
in serious personal injury or death.
A secondary air supply stores compressed breathing air
until needed to refill air mask air cylinders. When transfill-
ing, the secondary air supply pressure must be greater
than air mask cylinder pressure. Examples of air supply
includes: cascade air cylinder refilling systems; high pres-
sure compressor systems with a fixed reservoir; and an air
mask air cylinder which is not installed on an air mask.
DO NOT use the Quick-Fill System, URC Assembly, or
ExtendAire System accessories if there is any possibili-
ty that the environment contains a CBRN warfare agent.
These air mask accessories are not approved for use in
atmospheres containing CBRN warfare agents. Failure
to follow this warning can result in serious personal
injury or death.
