6. Evacuate and ventilate the area immediately after extinguishing the fire. The fumes and smoke from any
fire may be hazardous and can be deadly.
BEFORE PREPARING TO MOVE THE EXTINGUISHER TO THE RECHARGE LOCATION,
DETERMINATION MUST BE MADE THAT THE FIRE IS COMPLETELY EXTINGUISHED AND THERE IS
NO DANGER OF A FLASHBACK.
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)
NFPA 10 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(s) not broken or missing.
6. Examination for obvious physical damage, corrosion, leakage, or clogged nozzle.
7. Determine fullness by weighing.
8. Condition of tires, carriage, and hose.
MAINTENANCE
NFPA 10 At least once a year or more frequently if circumstances require, maintenance shall be
performed. Maintenance is a "thorough check" of the 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 fastened and legible. Inspect the cylinders for corrosion, abrasion, dents, or weld
damage. If any damage is found, hydrostatically test to factory test pressure 3000 psi (20.69 MPa) in
accordance with instructions in C-6 and NFPA 10.
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 of manufacture on the extinguisher cylinder dome. The agent cylinder must be
hydrostatically tested every 5 years to the test pressure indicated on the nameplate [3000 psi (20.69
MPa)]. Complete maintenance shall be performed whenever a hydrostatic test is being done. This
includes an inspection of the interior of the valve assembly, the spring, and the interior of the cylinder.
Install a new valve stem after lightly lubricating the O-ring with V-711 (do not lubricate the seal).
4. Check pull pin for freedom of movement. Replace if bent or if removal appears difficult.
