INTRODUCTION
When utilized, the Occupational Safety and Health Act
(OSHA) rules require that ‘‘the employer shall be responsible
for the inspection, maintenance, and testing of all portable
extinguishers in the work place.’’ Details are provided in the
Code of Federal Regulations 29 CFR 1910.157(e) and in
Appendixes A and B to Subpart L, referencing the provisions
of NFPA 10 as guidelines. The latest edition of NFPA 10
‘‘Standard for Portable Fire Extinguishers’’ is available from
the National Fire Protection Association, visit www.nfpa.org.
The Compressed Gas Association Inc. CGA C-6 ‘‘Standards
For Visual Inspection of Steel Compressed Gas Cylinders’’
and CGA C-6.1 ‘‘Standards For Visual Inspection of High
Pressure Aluminum Compressed Gas Cylinders’’ provides
information on determining unacceptable dents and corrosion.
It is available from the Compressed Gas Association, Inc., visit
www.cganet.com.
RESPONSIBILITY
The owner or occupant of a property in which fire extin-
guishers are located has an obligation for the care and use of
these extinguishers at all times. By doing so, he/she is contrib-
uting to the protection of life and property. The nameplates
and instruction manual should be read and thoroughly under-
stood by all personnel who may be expected to operate,
recharge, inspect or maintain the extinguishers.
!WARNING
When performing recharge, use only those materials specified
on the extinguisher nameplate. The use of other recharging
materials may reduce the efficiency, cause malfunction, or
result in rupture of the extinguisher that could cause injury to
the operator.
INSPECTION
Inspection is a ‘‘quick-check’’ to give reasonable assurance
an extinguisher is fully charged and operable. It includes
checking that an extinguisher is in its designated location, that
it has not been actuated or tampered with, and that there is
no obvious physical damage or condition to prevent operation.
The value of an inspection lies in the frequency, regularity,
and thoroughness with which it is conducted. The frequency
will vary from hourly to monthly, based on the needs of the
situation.
MAINTENANCE
Extinguishers shall be maintained at regular intervals, not
more than one year apart, or when specifically indicated by
an inspection. Maintenance is a ‘‘thorough check’’ to give
maximum assurance the extinguisher will operate effec-
tively and safely. It includes a thorough examination and any
necessary repair, recharge, or replacement. It will normally
reveal if there is a need for hydrostatic testing.
RECHARGE
All extinguishers shall be recharged immediately after use, or
when indicated by an inspection or maintenance examination.
Recharge is the replacement or replenishment of the
suppressing agent.
HYDROTEST
Extinguishers shall be hydrostatically tested at regular
intervals as required in the latest edition of NFPA 10,
‘‘Standard for Portable Fire Extinguishers,’’ or more frequently
when inspection or maintenance dictates a specific need.
Such tests are usually required on extinguisher shells and
some hose assemblies. For further details, see SENTRY/
CLEANGUARD Fire Extinguisher Hydrostatic Test Instructions
(Form No. T-2017001).
!WARNING
For safety: If, at any time, an extinguisher shows evidence of
corrosion or mechanical injury, it shall be subjected to a hydro-
static pressure test or replaced.
!WARNING
Do not use air or gas for pressure testing. Failure to comply
could result in severe personal injury or death if the shell
ruptures.
RECORD KEEPING
Each extinguisher shall have a tag or label securely attached
that indicates the month and year the maintenance was
performed and shall identify the person performing the service.
The same record tag or label shall indicate if recharging was
also performed. The tag shall not be placed on the front of
the extinguisher where it could obscure operating instructions.
At least monthly, the date the inspection was performed and
the initials of the person performing the inspection shall be
recorded.
In addition to the required tag or label, a permanent file
record should be kept for each extinguisher. The file record
should also include the maintenance date and the name of
the person or agency performing the maintenance; the date
when last recharged and the name of the person performing
the hydrostatic test; and a description of dents remaining after
passing a hydrostatic test.
Parts of the above taken from NFPA Pamphlet 10.

OPERATION
OPERATION
!WARNING
Carbon dioxide extinguishers contain a suppressing agent
that will not support life when used in sufficient concentration
to suppress a fire. The use of this type of extinguisher in an
unventilated space can dilute the oxygen supply. Prolonged
occupancy of such spaces can result in loss of consciousness
and possible death due to oxygen deficiency.
1. Remove extinguisher from its hanger.
2. Use handle to carry extinguisher to fire. Walk at a rapid
pace. DO NOT RUN.
3. Proceed to upwind side of fire. Stay well clear of flames.
From this position, air currents help carry agent into fire,
assure maximum visibility, provide protection from heat,
and lessen exposure to possible harmful vapors.
4. Start back from fire a distance recommended on
extinguisher nameplate. Holding extinguisher by handle,
grasp ring pin and pull straight out, breaking visual seal.
5. 5 lb Extinguisher: Position tube/horn assembly and
squeeze handle lever to discharge agent.
10, 15, or 20 lb Extinguishers: Hold the nozzle with one
hand and squeeze handle lever to discharge agent.

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.
