Portable Fire Extinguisher
Inspections.
(1) Disposable-type (non-gauged) Fire Extinguishers
Disposable-type fire extinguishers should be maintained and inspected in accordance with the
nameplate instructions.
(a) Monthly
Check monthly or more frequently. Ensure nozzle is not obstructed and safety seal is
intact. Inspection is a "quick check" that an extinguisher is available and will operate. It is
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
(discharged) or tampered with, and that there is no obvious physical damage or condition
to prevent operation. Determine fullness by weighing or "hefting."
(b) 100 Hour / Annual
Each 100 hours or annually, whichever comes first, weigh the extinguisher. Replace and
return to manufacturer if gross weight is below the minimum specified on the nameplate.
(c) Each Twelve (12) Years
Replace disposable-type (non-gauged) fire extinguishers at twelve (12) years from date of
manufacture.
(2) Rechargeable (gauged) Fire Extinguishers
Inspect rechargeable (gauged) fire extinguishers as follows:
(a) Monthly
Check fire extinguisher for condition and charge. Verify nozzle is unobstructed and the
lockpin is in place and the safety seal is intact. Verify that the gauge pressure is in the
operable (green) range and that the operating instructions are clearly visible.
(b) Annually
Each twelve (12) months, have the fire extinguisher professionally inspected.
(c) Each Six (6) Years
Each six years time-in-service, completely discharge the extinguisher and have it
professionally inspected and recharged.
(d) Each Twelve (12) Years
Hydrostatically test rechargeable (gauged) fire extinguishers each twelve (12) years time-
in-service.
