SHUTDOWN
1.
After making sure that the fire has been completely extinguished, push the nozzle lever forward to the
CLOSED position.
2.
Close the Argon cylinder valve (push
“
T
”
handle to closed position).
3.
Tip extinguisher over to rest on wheels and handle, then slowly open the nozzle lever again to clear the
hose of chemical agent and pressure (be prepared for recoil and discharge of agent).
WARNING: MAKE SURE THAT ALL PRESSURE HAS ESCAPED BEFORE FURTHER
DISASSEMBLY.
4.
Stand the extinguisher upright after complete depressurization. Note: Argon pressure in the agent cylinder
cannot escape through a disconnected pressurizing hose due to a check valve in the system. Always be
careful when removing the fill cap.
5.
Coil the extinguisher hose onto the storage rack, and position the nozzle (and/or Extension Wand) onto
the mount in preparation for transport to the recharge location.
WARNING: THE SHIPPING CAP MUST BE INSTALLED ON THE ARGON CYLINDER PRIOR TO
TRANSPORT TO THE RECHARGE LOCATION

INSPECTING THE EXTINGUISHER
INSPECTION
is a
“
quick check
”
that an extinguisher is available and will operate. It is intended to give
reasonable assurance that the extinguisher is fully charged and operable. This is done by seeing that it is in
its designed place, that it has not bee actuated or tampered with, and that there is no obvious physical
damage or condition to prevent operation.
PERIODIC INSPECTION PROCEDURES
(Monthly or more often if circumstances dictate)
A
“
quick check
”
shall be made of the extinguisher for the following:
1.
Located in designated place.
2.
No obstructions to access or visibility.
3.
Operating instructions on nameplate and facing outward.
4.
Tamper seal not broken or missing.
5.
Determine fullness by weighing on a scale with adequate capacity.
6.
Examine for obvious physical damage, corrosion, leakage, or clogged nozzle.
7.
Pressure gauge (Argon cylinder) reading in the operable area.
MAINTENANCE
At least once a year (or more frequently if indicated by an inspection), MAINTENANCE shall be performed.
MAINTENANCE is a
“
thorough check
”
of the extinguisher. It is intended to give maximum assurance that an
extinguisher will operate effectively and safely. It includes a thorough examination and any necessary repair
or replacement. It will normally reveal the need for hydrostatic testing
