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). In fire service applica-
tions, MSA recommends breathing air quality in accor-
dance with NFPA 1989. Pressures at the inlet of the
quick-fill hose must not exceed that of the air mask
(2216 psi or 4500 psi).
4. The user also is responsible for connecting the quick-
fill hose to an appropriate secondary air supply.
5. The cylinder must be inspected for damage before
charging.
6. 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 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.
•
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. In fire service applications, MSA recom-
mends breathing air quality in accordance with
NFPA 1989.
•
DO NOT lubricate the quick-fill fittings.
•
DO NOT permit oil, grease, or other contaminants
to come in contact with the quick-fill fittings.
•
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.
Misuse can result in serious injury or death.
DO NOT use the Quick-Fill
®
System, URC Assembly, or
ExtendAire™ System accessories if there is any possi-
bility that the environment contains a CBRN warfare
agent. These air mask accessories are not approved
for use in atmospheres containing CBRN warfare
agents. Misuse can result in serious 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 fittings
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.
FILLING INSTRUCTIONS FOR QUICK-FILL SYSTEM
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 or a
portable air system such as the MSA RescueAire™
System.
The following hoses can be used to connect to a sec-
ondary air supply.
