INSPECTION
INSPECTION
Inspection provides reasonable assurance the extinguisher is
charged and operable. Where an inspection reveals tampering
has occurred or the extinguisher is damaged, impaired,
leaking, or has obvious corrosion, the complete maintenance
as described on Pages 7-8 should be followed.
NOTICE
Become familiar with the Service and Repair
section prior to performing inspection.
1. Make certain extinguisher is in its designated place, is
clearly visible and is accessible for immediate use. Any
obstructions that obscure it, or that would otherwise
impair its being readily accessible, should be removed.
2. Check visual seal on valve lever. The absence of a seal
or a broken seal may indicate either unreported use or
tampering. In either case, a complete maintenance check
is required.
3. Extinguisher shall be weighed or hefted every month and
recharged if weight loss is in excess of 1 lb (0.45 kg) or if
overweight. Total charged weight is stamped on the valve
body and includes hose and horn assembly.
4. Remove extinguisher from its wall hanger or bracket.
Examine extinguisher for evidence of physical damage,
corrosion or other impairments.
5. Check nameplate for readability.
6. Examine horn or horn/hose assembly for cuts, severe
weather checking, abrasion, cracks or deformed exterior.
7. Check hose couplings for tightness, corrosion or cracks.
A loose connection on the coupling could contribute
to a significant change in discharge characteristics. A
corroded or cracked coupling could separate under pres-
sure.
8. Check horn for obstruction. Insects are common causes
of obstructions particularly in warmer climates.
9. Make sure wall hanger or bracket is properly fastened to
hold total extinguisher weight.
10. Return extinguisher to its designated location.
11. Personnel making inspections are usually required to
keep records by way of marking a tag attached or affixed
to the extinguisher and/or in a permanent file. Your
precise guide to record keeping requirements should be
the applicable company, local, state or federal authority
having jurisdiction.
12. Record the date of recharge on the tag (Part No. 2364)
affixed or attached to the extinguisher and in your
permanent file record in accordance with company, local,
state or federal codes, regulations or standards.
