INSPECTING THE EXTINGUISHER
PERIODIC INSPECTION PROCEDURES
(monthly or more often if circumstances dictate)
NFPA 10 - Periodic inspection of fire extinguishers shall include a check of at least the following items:
1. Location in designated place
2. No obstruction to access or visibility
3. Operating instructions on nameplate legible and facing outward
4. Seals and tamper indicators not broken or missing
5. Determine fullness by weighing
6. Examination for obvious physical damage, corrosion, leakage, or clogged nozzle
7. Pressure gauge reading in the operable range
8. Hose properly coiled and shut-off nozzle in its mount in closed position
9. Condition of tires/wheels and that they rotate freely
10. HMIS label in place
MAINTENANCE
(At least once a year or when specifically indicated by an inspection)
MAINTENANCE PROCEDURE
1. Clean extinguisher to remove dirt, grease or foreign material. Check to make sure that the instruction
nameplate and UL manifest are securely fastened and legible. Inspect the cylinder for corrosion, abra-
sion, and 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 NFPA 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. Weigh extinguisher and compare with weight printed in the Maintenance section on the nameplate. Re-
charge extinguisher if weight is not within indicated allowable tolerances.
4. Check the date of manufacture stamped into the cylinder. Cylinder must be hydrostatically (proof pres-
sure) tested every 12 years to the test pressure indicated on the nameplate. Model 673, 65 lb. = 480
psi (3309 kPa); Models 674 and 675, 150 lb. = 1000 psi (6895 kPa).
INSPECTION (NFPA 10) 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 tam-
pered with, and that there is no obvious physical damage or condition to prevent its operation.
INSPECTION (NFPA 10) is a thorough examination of the fire extinguisher. It is intended to
give maximum assurance that the fire extinguisher will operate effectively and safely. It includes
a thorough examination for physical damage or condition to prevent its operation and any nec-
essary repair or replacement. It will normally reveal if hydrostatic testing or internal mainte-
nance is required.
