Subpart 25.30—Fire Extinguishing
Equipment

Servicing of EPIRBs.

(a) The master of each vessel required to have an EPIRB under this
subpart shall ensure that each EPIRB
on board is tested and serviced as required by this section.
(b) The EPIRB must be tested immediately after installation and at least
once each month thereafter, unless it
is an EPIRB installed in a Coast Guard
approved inflatable liferaft that is tested annually during the servicing of the
liferaft by an approved servicing facility. The test shall be conducted in accordance with the manufacturer’s instructions, using the visual or audio indicator on the EPIRB. If the EPIRB is
not operating, it must be repaired or
replaced with an operating EPIRB.
(c) The battery of the EPIRB must be
replaced—
(1) Immediately after the EPIRB is
used for any purpose other than being
tested; and
(2) Before the expiration date that is
marked on the battery.

Exemptions.

(a) A skiff or work boat is not required to carry an EPIRB if—
(1) Its ‘‘mother ship’’ is required to
carry an EPIRB under this subpart;
and
(2) When not in use, the skiff or work
boat is carried on board the mother
ship.
(b) Each Coast Guard District Commander may, on a case-by-case basis,
grant exemptions from the carriage requirements of EPIRBs in this subpart
for certain geographic areas within the
boundaries of his or her own district if
the District Commander determines
that an EPIRB will not significantly
enhance the overall safety of the vessel
and crew. Exemptions may be limited
to specific time periods. Exemptions
granted under this paragraph must be:
(1) Issued in writing by the cognizant
Coast Guard District Commander for
each individual application; and
(2) For geographic locations and may
be limited to specific time periods.

§ 25.30–1 Application.
(a) The provisions of this subpart,
with the exception of § 25.30–90, shall
apply to all vessels contracted for on or
after November 19, 1952. Vessels contracted for prior to that date shall
meet the requirements of § 25.30–90.
§ 25.30–5 General provisions.
(a) Where equipment in this subpart
is required to be of an approved type,
such equipment requires the specific
approval of the Commandant. Such approvals are published in the FEDERAL
REGISTER, and in addition, are contained in Coast Guard publication
COMDTINST M16714.3 (Series), Equipment Lists.
(b) All hand portable fire extinguishers, semiportable fire extinguishing systems, and fixed fire extinguishing systems shall be of an approved type.

§ 25.30–10 Hand portable fire extinguishers and semiportable fire extinguishing systems.
(a) Hand portable fire extinguishers
and semiportable fire extinguishing
systems are classified by a combination letter and number symbol. The
letter indicating the type of fire which
the unit could be expected to extinguish, and the number indicating the
relative size of the unit.
(b) For the purpose of this subchapter, all required hand portable fire
extinguishers and semiportable fire extinguishing systems are of the ‘‘B’’
type; i.e., suitable for extinguishing
fires involving flammable liquids,
greases, etc.
(c) The number designations for size
will start with ‘‘I’’ for the smallest to
‘‘V’’ for the largest. For the purpose of
this subchapter, only sizes I through
III will be considered. Sizes I and II are
considered hand portable fire extinguishers and sizes III, IV, and V are
considered semiportable fire extinguishing systems which shall be fitted
with suitable hose and nozzle or other
practicable means so that all portions

(d) All hand portable fire extinguishers and semiportable fire extinguishing systems shall have permanently attached thereto a metallic
name plate giving the name of the
item, the rated capacity in gallons,
quarts, or pounds, the name and address of the person or firm for whom
approved, and the identifying mark of
the actual manufacturer.
(e) Vaporizing-liquid type fire extinguishers containing carbon tetrachloride or chlorobromomethane or
other toxic vaporizing liquids are not

serviceable condition. The following
maintenance and inspections are required for such extinguishers:
(1) When the date on the inspection
record tag on the extinguishers shows
that 6 months have elapsed since last
weight check ashore, then such extinguisher is no longer accepted as meeting required maintenance conditions
until reweighed ashore and found to be
in a serviceable condition and within
required weight conditions.

(2) If the weight of the container is 1⁄4
ounce less than that stamped on container, it shall be serviced.
(3) If the outer seal or seals (which
indicate tampering or use when broken) are not intact, the boarding officer or marine inspector will inspect
such extinguisher to see that the frangible disc in neck of the container is
intact; and if such disc is not intact,
the container shall be serviced.
(4) If there is evidence of damage,
use, or leakage, such as dry chemical
powder observed in the nozzle or elsewhere on the extinguisher, the container shall be replaced with a new one
and the extinguisher properly serviced
or the extinguisher replaced with another approved extinguisher.
(h) The dry chemical, stored pressure, fire extinguishers without pressure gauges or indicating devices manufactured after January 1, 1965, shall
not be labeled with the marine type
label bed in § 162.028–4 of this title nor
shall such extinguishers manufactured
after January 1, 1965, be carried on
board motorboats or other vessels as
required equipment.
