INSPECTING THE EXTINGUISHER
NFPA 10
-
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)
A

Located in designated place.
2.
No obstructions to access or visibility.
3.
Operating instructions on pictogram and facing outward.
4.
Tamper seal not broken or missing.
5.
Determine fullness by weighing (full weight is noted on the nameplate).

MAINTENANCE

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 is required.
