AFTER USE INSTRUCTIONS NOTE
Fire extinguishers should always be recharged immediately after any use.
1.
Invert extinguisher, then while securing and pointing the nozzle in a safe direction, squeeze
the operating levers to clear hose and release all remaining pressure from the extinguisher.
2.
Notify responsible person that extinguisher was used, so that the extinguisher can be
immediately recharged, or a replacement obtained
WARNING
a.
Before attempting to disassemble, be sure the extinguisher is completely depressurized. To
depressurize – hold the extinguisher in an inverted position and slowly squeeze the discharge
handle and lever. See trouble shooting section for more details.
b.
Never have any part of your body over the extinguisher while removing the valve assembly.
c.
Use a protective shield between you and the valve while charging an extinguisher. Do not stand in
front of the valve if a shield is not available.
d.
Check and calibrate regulator gauge at frequent intervals. The regulator gauge should be used to
determine when the intended charging pressure has been reached. Do not use the extinguisher
gauge for this purpose.
e.
Never leave an extinguisher connected to a regulator of a high-pressure source for an extended
period. A defective regulator could cause the cylinder to rupture due to excessive pressure.
CAUTION
Discharge time and effective range of the agent throw varies according to model – see the specification
literature for your extinguisher.
INSPECTING THE EXTINGUISHER
The inspection procedures outlined below may not be sufficient for every jurisdiction or location and
should be used in conjunction with the NFPA 10 Standard for Portable Fire Extinguishers, 2022
Edition.
This extinguisher should be inspected at regular intervals (monthly or more often if
circumstances dictate) to ensure that it is ready for use. Inspection is a "quick check" that a fire
extinguisher is available and is in good operating condition with no damage or corrosion. It is
intended to give reasonable assurance that the fire extinguisher is fully charged with no loss of
pressure (pointer in green zone), tamper seal is unbroken and no obstructions in hose or nozzle.
This is done by verifying that it is in its designated place, that it has not been actuated or
tampered with, and that there is no obvious physical damage or condition to prevent its
operation.
WARNING
For safety purposes, if an extinguisher shows signs of corrosion or mechanical damage, it shall be
subjected to a hydrostatic pressure test or replaced.
