INSPECTING THE EXTINGUISHER
MAINTENANCE
At least once a year or more frequently if circumstances require, maintenance should 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.
NOTE: The Getz Manufacturing Universal Wheeled Extinguisher Service Kit is available so that NFPA-10
required maintenance functions can be performed.
MAINTENANCE
– SERVICE PROCEDURE
WARNING: BEFORE SERVICING BE SURE THE EXTINGUISHER AGENT CYLINDER IS NOT
PRESSURIZED. THIS PROCEDURE IS BEST ACCOMPLISHED WITH THE EXTINGUISHER
IN AN UPRIGHT POSITION AND ON A LEVEL SURFACE.
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 in accordance with instructions in CGA C-1 and C-6
and NFPA 10.
2. Inspect the extinguisher for damaged, missing or substitute parts. A careful inspection should be made of
the safety relief to make sure that it has not ruptured, corroded or been tampered with. ONLY FACTORY
REPLACEMENT PARTS ARE APPROVED FOR USE ON AMEREX FIRE EXTINGUISHERS.
3. Check the date of manufacture printed on the extinguisher label (nameplate) or on the agent cylinder
dome. The agent cylinder, the discharge hose assembly and nitrogen supply hose must be
hydrostatically tested every 12 years. Test pressure:
a. Agent Cylinder – 500 psi (3447 kPa)
b. Hose Assembly – 300 psi (2068 kPa)
c. Nitrogen Supply Hose – 3000 psi (20,682 kPa)
4. Check the hydrostatic test date on the crown of the nitrogen cylinder. The nitrogen cylinder must be
retested in accordance with DOT regulations.

This extinguisher should 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.
