offices vary throughout the country,
no specific routing will be required in
the submittal of plans. In general, one
of the following procedures would
apply, but in a particular case, if a
more expeditious procedure can be
used, there will be no objection to its
adoption.
(1) The plans may be submitted to
the Officer in Charge, Marine Inspection, in the district in which the vessel
is to be built. This procedure will be
most expeditious in the case of those
offices where personnel and facilities
are available for examination and approval of the plans locally.

directly to the submitter, with a copy
of the action being forwarded to the interested Officer in Charge, Marine Inspection.
(3) The plans may be submitted by
visitors directly to Commanding Officer, U.S. Coast Guard Marine Safety
Center, 1900 Half Street, SW., Suite
1000, Room 525, Washington, DC 20024,
or transmitted by mail to: Commanding Officer, U.S. Coast Guard Marine Safety Center, 2100 2nd St., SW.,

§ 92.25–1

Where rails required.

(a) All vessels shall have efficient
guard rails or bulwarks on decks and
bridges. The height of rails or bulwarks
shall be at least 391⁄2 inches from the
deck except that where this height
would interfere with the normal operation of the vessel, a lesser height may
be approved by the Commandant. At
exposed peripheries of the freeboard
and superstructure decks, the rails
shall be in at least three courses, including the top. The opening below the
lowest course shall not be more than 9
inches. The courses shall not be more
than 15 inches apart. In the case of
ships with rounded gunwales the guard
rail supports shall be placed on the flat
of the deck. On other decks and bridges
the rails shall be in at least two
courses, including the top, approximately evenly spaced. If it can be
shown to the satisfaction of the Officer
in Charge, Marine Inspection, that the
installation of rails of such height will
be unreasonable and impracticable,
having regard to the business of the
vessel, rails of a lesser height or in
some cases grab rails may be accepted
and inboard rails may be eliminated if
the deck is not generally accessible.
(b) Where it can be shown to the satisfaction of the Commandant that a
vessel is engaged exclusively in voyages of a sheltered nature, the provisions of paragraph (a) of this section

§ 95.10–5

§ 95.10–10
(f) Fire pumps may be used for other
purposes provided at least one of the
required pumps is kept available for
use on the fire system at all times. In
no case shall a pump having connection
to an oil line be used as a fire pump.
Branch lines connected to the fire main
for purposes other than fire and deck
wash shall be so arranged that adequate water can be made continuously
available for firefighting purposes.
(g) The total area of the pipes leading
from a pump shall not be less than the
discharge area of the pump.
(h) On vessels with oil fired boilers,
either main or auxiliary, or with internal combustion propulsion machinery,
where 2 fire pumps are required, they
shall be located in separate spaces, and
the arrangement of pumps, sea connections, and sources of power shall be
such as to insure that a fire in any one
space will not put all of the fire pumps
out of operation. However, where it is
shown to the satisfaction of the Commandant that it is unreasonable or impracticable to meet this requirement
due to the size or arrangement of the
vessel, or for other reasons, the installation of a total flooding carbon dioxide system may be accepted as an alternate method of extinguishing any
fire which would affect the powering
and operation of at least one of the required fire pumps.

Fire pumps.

good commercial grade together with a commercial garden
hose nozzle may be used. The pump may be hand operated
and the length of hose shall be sufficient to assure coverage
of all parts of the vessel.
2 75 feet of 11⁄2-inch hose and 5⁄8-inch nozzle may be used
where specified by § 95.10–10(b) for interior locations and 50
feet of 11⁄2-inch hose may be used in exterior locations on
vessels in other than ocean or coastwise service.

(b) On vessels of 1,000 gross tons and
over on an international voyage, each
required fire pump, while delivering
water thru the fire main system at a
pressure corresponding to that required
by paragraph (c) of this section, shall
have a minimum capacity of at least
two-thirds of that required for an independent bilge pump. However, in no
case shall the capacity of each fire
pump be less than that otherwise required by this section.
(c) Each pump shall be capable of delivering water simultaneously from the
two highest outlets at a Pitot tube
pressure of approximately 50 p.s.i.
Where 11⁄2-inch hose is permitted in lieu
of 21⁄2-inch hose by footnote 2 of Table
95.10–5(a), the pump capacity shall be
determined on the same basis as if 21⁄2inch hose had been permitted. Where
3⁄4-inch
hose is permitted by Table
95.10–5(a), the Pitot tube pressure need
be only 35 p.s.i.
(d) Fire pumps shall be fitted on the
discharge side with relief valves set to
relieve at 25 p.s.i. in excess of the pressure necessary to maintain the requirements of paragraph (c) of this section
or 125 p.s.i., whichever is greater. Relief valves may be omitted if the
pumps, operating under shut-off conditions, are not capable of developing a
pressure exceeding this amount.
(e) Fire pumps shall be fitted with a
pressure gage on the discharge side of
the pumps.

(b) In lieu of the 21⁄2-inch hose and
hydrants specified in Table 95.10–5(a),
on vessels over 1,500 gross tons, the hydrants in interior locations may have
siamese connections for 11⁄2-inch hose.
In these cases the hose shall be 75 feet
in length, and only one hose will be required at each fire station; however, if
all such stations can be satisfactorily
served with 50-foot lengths, 50-foot
hose may be used.

and check valves must be provided.
Suitable adapters also must be provided for furnishing the vessel’s shore
connections with couplings mating
those on the shore fire lines. Vessels of
500 gross tons and over on an international voyage, must be provided with
at least one international shore connection complying with ASTM F 1121
(incorporated by reference, see § 95.01–
2). Facilities must be available enabling an international connection to be
used on either side of the vessel.
(d) Fire hydrants shall be of sufficient number and so located that any
part of the vessel, other than main machinery spaces, accessible to persons on
board while the vessel is being navigated and all cargo holds may be
reached with at least 2 streams of
water from separate outlets, at least
one of which shall be from a single
length of hose. In main machinery
spaces, all portions of such spaces shall
be capable of being reached by at least
2 streams of water, each of which shall
be from a single length of hose from
separate outlets; however, this requirement need not apply to shaft alleys
containing no assigned space for the
stowage of combustibles. Fire hydrants
shall be numbered as required by
§ 97.37–15 of this subchapter.
(e) All parts of the fire main located
on exposed decks shall either be protected against freezing or be fitted
with cut-out valves and drain valves so
that the entire exposed parts of such
piping may be shut off and drained in
freezing weather. Except when closed
to prevent freezing, such valves shall
be sealed open.
(f) The outlet at the fire hydrant
shall be limited to any position from
the horizontal to the vertical pointing
downward, so that the hose will lead
horizontally or downward to minimize
the possibility of kinking.
(g) Each fire hydrant must have at
least one length of firehose, a spanner,
and a hose rack or other device for
stowing the hose.
(h) Fire hose shall be connected to
the outlets at all times. However, on
open decks where no protection is afforded to the hose in heavy weather, or
where the hose may be liable to dam-

age from the handling of cargo, the
hose may be temporarily removed from
the hydrant and stowed in an accessible nearby location.
(i) Each firehose on each hydrant
must have a combination solid stream
and water spray firehose nozzle approved under subpart 162.027 of this
chapter. Firehose nozzles previously
approved under subpart 162.027 of this
chapter may be retained so long as
they are maintained in good condition
to the satisfaction of the Officer in
Charge, Marine Inspection.
(j) In each propulsion machinery
space containing an oil fired boiler, internal combustion machinery, or oil
fuel unit on a vessel on an international voyage or of 1000 gross tons or
more, each firehose having a combination nozzle previously approved under
subpart 162.027 of this chapter must
have a low-velocity water spray applicator that is also previously approved
under subpart 162.027 of this chapter.
The length of the applicator must be
less than 1.8 meters (6 feet).
(k) Fixed brackets, hooks, or other
means for stowing an applicator must
be next to each fire hydrant that has
an applicator under paragraph (j) of
this section.
(l) Firehose shall not be used for any
other purpose than fire extinguishing,
drills, and testing.
(m) Fire hydrants, nozzles, and other
fittings shall have threads to accommodate the hose connections noted in
paragraph (l) of this section.
(n) Firehose and couplings must be as
follows:
(1) Fire station hydrant connections
shall be brass, bronze, or other equivalent metal. Couplings shall either:
(i) Use National Standard fire hose
coupling threads for the 11⁄2 inch (38
millimeter) and 21⁄2 inch (64 millimeter)
hose sizes, i.e., 9 threads per inch for
11⁄2 inch hose, and 71⁄2 threads per inch
for 21⁄2 inch hose; or
(ii) Be a uniform design for each hose
diameter throughout the vessel.
(2) Where 19 millimeters (3⁄4 inch)
hose is permitted by table 95.10–5(a),
the hose and couplings shall be of good
commercial grade.
(3) Each section of firehose must be
lined commercial firehose that conforms to Underwriters’ Laboratories,

§ 95.15–5 Quantity, pipe sizes, and discharge rates.
(a) General. The amount of carbon dioxide required for each space shall be
as determined by paragraphs (b)
through (d) of this section.
(b) Total available supply. A separate
supply of carbon dioxide need not be
provided for each space protected. The
total available supply shall be at least
sufficient for the space requiring the
greatest amount.
(c) Cargo spaces. (1) The number of
pounds of carbon dioxide required for
each space shall be equal to the gross
volume of the space in cubic feet divided by 30.
(2) Although separate piping shall be
led to each cargo hold and ’tween deck,
for the purpose of determining the
amount of carbon dioxide required, a
cargo compartment will be considered
as the space between watertight or
firescreen bulkheads and from the tank
top or lowest deck to the deck head of
the uppermost space on which cargo
may be carried. If a trunk extends be-
