INSPECTING THE EXTINGUISHER
This extinguisher must be inspected at regular intervals (monthly or more often if circumstances dictate) to
insure that it is ready for use. Inspection is a "quick check" that a fire extinguisher is available and is in
operating condition. It is intended to give reasonable assurance that the fire extinguisher is fully charged. 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.
PERIODIC INSPECTION PROCEDURES
(Monthly or more often if circumstances dictate)
Periodic inspection of fire extinguishers shall include a check of at least the following items:
1. Located in designated place.
2. No obstruction to access or visibility.
3. Pressure gauge reading or indicator in the operable range or position.
4. Operating instructions on nameplate and facing outward.
5. Tamper seal not broken or missing.
6. Examination for obvious physical damage, corrosion, leakage, or clogged nozzle.
7. Fullness determined by weighing or hefting.
MAINTENANCE
Extinguishers shall be subjected to maintenance at intervals of not more than 1 year, at the time of
hydrostatic test or when specifically indicated by an inspection or electronic notification. Maintenance
procedures include a thorough examination of the basic elements of a fire extinguisher:
1. Mechanical parts
2. Extinguishing agent or cartridge of cylinder operated extinguishers, pump tanks, and certain types of
stored-pressure extinguishers
3. Expelling means
NOTE: Stored pressure halon 1211 extinguishers do not require an internal examination of the
cylinder or examination of the agent during annual maintenance but shall receive a
thorough external examination.
Maintenance is a thorough examination of the fire extinguisher. It is intended to give maximum assurance that
a fire extinguisher will operate effectively and safely. It includes a thorough examination for physical damage
or condition to prevent its operation and any necessary repair or replacement. It will normally reveal if
hydrostatic testing or internal maintenance is required.
MAINTENANCE – SERVICE PROCEDURE
1. Clean extinguisher to remove dirt, grease, or foreign material. Check to make sure that the instruction
nameplate is securely attached and legible. Inspect the cylinders for corrosion, abrasion, dents, or weld
damage. If any of these conditions are found and you doubt the integrity of the cylinder, hydrostatically
test to factory test pressure, using the proof-pressure method in accordance with CGA C-1 and C-6 and
NFPA 10. See proper method of depressurizing and reclaiming Halon 1211 in SIX-YEAR
MAINTENANCE/RECHARGE PROCEDURE.
Note: When cleaning, avoid use of solvents around the pressure gauge. They could seriously
damage the plastic gauge face.
2. Inspect the extinguisher for damaged, missing, or substitute parts. Only factory-replacement parts are
approved for use on Amerex fire extinguishers.
