INSPECTION
INSPECTION (NFPA 10) is a "quick check intended to give reasonable assurance that the extinguisher is fully
charged and operable. This is done by seeing 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 operation.
PERIODIC INSPECTION PROCEDURES
(Monthly or more often if circumstances dictate)
( NFPA 10) A "quick check" should 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. Seals and tamper indicators not broken or missing.
5. Determine fullness by weighing or "hefting".
6. Examine for obvious physical damage, corrosion, leakage or clogged nozzle..
7. Pressure gauge reading in the operable area.
MAINTENANCE
MAINTENANCE (NFPA-10) At least once a year (or more frequently if indicated by any inspection),
Maintenance is a "thorough check" of an extinguisher. It is intended to give maximum assurance that an
extinguisher will operate effectively and safely. It includes a thorough examination and any unnecessary repair
or replacement. It will normally reveal the need for hydrostatic testing.
MAINTENANCE PROCEDURE
1. Clean extinguisher to remove dirt, grease or foreign material. Check to make sure that the instruction
nameplate and FM manifest are securely fastened and legible. Inspect the cylinder 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 (585 psi [4035 kPa]), using the proof pressure
method, in accordance with CGA Pamphlet C-6 and NFPA Pamphlet 10. See proper method of
depressurizing and reclaiming chemical in "Recharge Procedures". 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.
3. Weigh extinguisher and compare with weight printed in the "Maintenance" section on the nameplate
(label). Recharge the extinguisher if weight is not within indicated allowable tolerances. (See instructions
in "Recharge Procedure").
