INSPECTING THE EXTINGUISHER
This extinguisher should be inspected at regular intervals (monthly or more often if circumstances
require) to insure that it is ready for use.
INSPECTION (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 (label) 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
– SERVICE PROCEDURE
MAINTENANCE (NFPA-10) At least once a year (or more frequently if indicated by an inspection),
maintenance should 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.
1. Clean extinguisher to remove dirt, grease or foreign material. Check to make sure that the
instruction nameplate is 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, using the proof pressure method and a suitable
cage, in accordance with CGA Pamphlet C-1 and NFPA Pamphlet 10. 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. Check the date when last recharged. The foam charge must be replaced every three years
with the proper Amerex charge (model 502 AFFF charge for models 250 and 254, model
504 FFFP for model 252). If the extinguisher is to be hydrotested do not reuse the charge
even if within a three year cycle (the foaming action will make it almost impossible to get
complete charge back into the extinguisher).
4. Weigh extinguisher and compare with weight printed on the Maintenance section of the
nameplate (label). Recharge extinguisher if weight is not within the indicated allowable
tolerances.
