PREFACE
The January 1935 edition of Appendix 10 has been revised by
incorporating therein the modifications, dated December 26, 1935,
issued with Bureau of Construction and Repair letter, dated January
10, 1936, No. A10/S28-(11).
The requirements of the 1935 edition have been further changed as
regards the materials of the label plates, the method of securing, and
the substitution of engraving for etching. In general, the material
has been changed from corrosion-resisting steel to brass and the
method of securing from spot welding to machine screws.
The following nomenclature of decks shall be followed for United
States naval vessels.
2. MAIN DECK.
The highest deck extending from stem to stern shall be called
the "main deck."
3. DECKS ABOVE MAIN DECK.
A partial deck above the main deck at the bow shall be called
the "forecastle deck"; at the stern, "poop deck"; amidships,
"upper deck."
The name "upper deck", instead of "forecastle deck" or "poop
deck", shall be applied to a partial deck extending from the waist
to either bow or stern.
A partial deck above the main, upper, forecastle, or poop deck
and not extending to the side of the ship, shall be called the
"superstructure deck."1
4. DECKS BELOW MAIN DECK.
A complete deck below the main deck shall be called the "second deck." Where there are two or more complete decks below
the main deck they shall be called the "second deck", "third
deck", "fourth deck", etc.
A partial deck above the lowest complete deck and below the
main deck shall be called the "half deck."
A partial deck below the lowest complete deck shall be called
the "platform deck." Where there are two or more partial decks
below the lowest complete deck, the one immediately below the
lowest complete deck shall be called the "first platform", the next
shall be called the "second platform", and so on.
5. PROTECTIVE DECKS.
Decks which for protective purposes are fitted with plating of
extra strength and thickness shall be further defined, for technical
1The Bureau interprets this as meaning that a deck structure, although extending to the line of
the ship's aide, is not an upper deck unless the side plating proper of the ship is carried up and connected to it.
2
purposes, as "protective" and "splinter", in addition to their
regular names. Where there is only one such deck it shall be
defined as "protective" and where there are two, that having the
thicker plating shall be defined as "protective" and that having
the thinner plating shall be defined as "splinter" in addition to
the regular names.
Where a protective deck is stepped a complete deck height the
respective portions shall be distinguished by means of the terms
"middle protective section" and "forward (or after) protective
section" in addition to the regular names. Where a splinter deck
is stepped a complete deck height, the respective portions shall
be similarly distinguished.
Where a portion of the protective or splinter deck is sloped the
sloping portion shall be defined as the "inclined protective deck"
or "inclined splinter deck."
3
CHAPTER 2 SPECIFICATIONS FOR NUMBERING WATERTIGHT COMPARTMENTS
1. SUBDIVISION.
The ship shall be considered as divided into three principal
divisions, lettered A, B, and C, from forward aft.
Division A.-This shall comprise all of the space between the
stem and the forward transverse bulkhead of the forward
machinery compartment.
Division B.-This shall comprise all of the space between the
forward transverse bulkhead of the forward machinery compartment and the after transverse bulkhead of the after machinery
compartment.
Division C.-This shall comprise all of the space aft of the after
transverse bulkhead of the after machinery compartment.
The term "machinery compartment" shall be construed as
meaning boiler rooms, engine rooms, main motor rooms, and
compartments in which auxiliaries of the main propelling machinery are located.
Where the number of the compartments in the 1 to 100 series
exceeds 100 in any principal division the matter shall be referred
to the Bureau.
These divisions shall be considered as extending from the keel to
the highest deck in the line of the bulkheads, or the bulkheads prolonged. In case the bulkheads do not extend to the highest deck
any space between decks that extends through two of the principal
divisions shall be numbered as if it were situated entirely in the
forward division of the two in which it is placed, and shall have
this number only. Main compartments with permanent openings
to the top side, such as boiler rooms, shall be considered as completely bounded by tight structure for numbering purposes.
2. NUMBERING.
All numbers in each division shall begin at the forward end of
that division.
Compartments on the starboard side of the ship shall have odd
numbers; those on the port side, even numbers.
All compartments and spaces that are completely bounded by
watertight, oiltight, airtight, or fumetight structure shall be numbered.
4
Where a watertight compartment located below the weather
deck is divided into two or more airtight or fumetight spaces by
airtight or fumetight bulkheads, the appropriate number shall be
assigned the watertight compartment and each airtight or fumetight subdivision within the compartment shall be designated by
the addition of a suffix to this number. Thus, if watertight compartment A-312L contains a fumetight or airtight bulkhead the
space to starboard of this bulkhead will be designated as A-312-1L
and the space to port as A-312-2L.
Where an airtight or fumetight compartment is located in a
watertight compartment which extends through two or more deck
levels, the airtight or fumetight compartment shall be numbered
as specified in the preceding paragraph, unless to do so would
result in illogical numbering, in which case the matter shall be
referred to the Bureau. Thus, a boiler room and its airlock would
be numbered B-1-1 and B-1-2, respectively. However, where
reference is made in correspondence to the entire watertight
space, the basic number without suffixes may be used, as B-1 or
A-312.
Care shall be exercised to insure that each numbered compartment or space is bounded completely by tight structure, that is,
assigning two numbers to adjoining spaces not separated by tight
structure shall be avoided.
Airtight and fumetight spaces located above the weather decks
and outside of the hull proper, such as those in deck houses, shall
each be given its own individual number without a suffix number,
in the same manner as if each airtight or fumetight space were a
separate watertight compartment. Thus, the number of an airtight or fumetight space on the superstructure deck may be
A-0204L, even though this space may be one of a number of
airtight or fumetight spaces located within a deckhouse with
watertight boundary.
Oiltight and watertight compartments on the main deck shall
be numbered from 101 to 199, and those on each successive deck
or platform below the main deck shall be numbered in the next
higher hundred series, namely those on the second deck shall be
numbered from 201 to 299; on the third deck from 301 to 399, etc.
Watertight, compartments on the next deck or platform above
the main deck shall be numbered 0101 to 0199, and those on each
successive deck or platform above the main deck shall be numbered
in the next higher hundred series, prefixed with a zero. For
example, a ship that has a superstructure, forecastle, main, second,
and third deck, and a first and second platform, the oiltight and
watertight compartments will be numbered as follows:
5
On superstructure deck
0201 to 0299
On forecastle deck
0101 to 0199
On main deck
101 to 199
On second deck
201 to 299
On third deck
301 to 399
On first platform
401 to 499
On second platform
501 to 599
In hold, if there are no more platforms
601 to 699
Double bottom compartments shall be numbered from 901 to
999.
It will be noted that the prefix zero of a compartment number
indicates that the compartment is above the main deck.
If there is not a third deck the compartments on the first and
second platforms and in the hold shall be numbered 301 to 399,401
to 499, and 501 to 599 respectively. If there is a fourth deck the
compartments on the fourth deck and first and second platforms
and hold shall be 401 to 499, 501 to 599, 601 to 699, and 701 to 799
respectively.
On modern destroyers the compartment numbers will be as
follows:
On main deck
101 to 199
On first platform
201 to 299
On second platform
301 to 399
In hold
401 to 499
Compartments with no decks, extending from inner bottom or
outside plating through two or more deck spaces, such as those
in protective layers, engine rooms, boiler rooms, deep peak tanks,
fuel-oil tanks on certain battleships, cargo holds, etc., shall be
numbered from 1 up to 100. Boiler and engine rooms shall be
given the lowest numbers, B-1, B-2, B-3, etc.
Where there is a half deck owing to the sheer or other cause, or
where there is a flat between regular decks, such as cofferdam fiat
over oil tank, no change in the hundred series shall be made on
account thereof.
The above scheme of numbering is intended to give an indication
of the vertical location of the compartment which, in connection
with the divisional fore and aft location, will give a very fair idea
of the position of the compartment.
The number of a compartment shall always be prefixed with
the letter indicating the general division of the ship in which it is
placed and separated from the number by a hyphen, as A-21,
B-3, etc.
When, after several plans involving compartment numbers have
been completed, it becomes necessary to increase the number of
compartments, half numbers may be assigned to the new compartments in order to avoid extensive renumbering. Half numbers
944557 O-51-2
6
shall not be used where the renumbering of only a few compartments is involved.
To further define the contents or main use of a compartment, the
compartment number shall be followed by a designating letter, as
follows:
A for storerooms, including:
Band room.
Refrigerator compartments.
Storerooms proper.
Tool and supply rooms.
Unassigned compartments usable as storerooms.
B for battery compartments, including:
Secondary battery compartments.
Torpedo rooms.
All compartments within turrets, including turret handling rooms.
C for ship control and fire control, including:
Central.
Coding room.
Interior communication.
Plotting room.
Main communication station.
Radio rooms.
Switchboard room (secondary battery).
Torpedo tracking room.
E for machinery compartments, including:
Blower room.
Boiler room.
Distribution room.
Evaporator room.
General workshop.
Gyro stabilizer room.
Ice-machine room.
Main engine room.
Main motor room.
A double bottom compartment used for feed water shall be
designated B-910 W, for oil B-909 F, if void A-902 V.
When a space is devoted to several main purposes, two or more
designating letters shall be used. Thus a living compartment containing secondary battery guns shall be designated B-115 B L.
3. NOMENCLATURE OF MACHINERY SPACES.
The nomenclature used in correspondence, in specifications, and
on plans for machinery spaces shall be as follows:
Fireroom.-A compartment containing boilers and the station
for "firing" or operating same.
Boiler Room.-A compartment containing boilers but not containing station for "firing" or operating the boilers.
Boiler Operating Station.-A station from which a boiler or
boilers are operated.
Boiler Central Control Station.-A station for directing control of
all boilers at boiler operating stations.
Boiler Emergency Station.-A station for a chief water tender
from which he may proceed with minimum delay to any fireroom,
boiler operating station or boiler room from which trouble has been
reported.
Engine Room.-A compartment in which main propelling unit
or units are installed.
Engine Operating Station.-A location or compartment from
which a main propelling unit or units are operated.

CHAPTER 3 SPECIFICATIONS FOR LABELING
1. GENERAL.
Label plates and tags shall be of two types-engraved and
embossed, except historical label plates, which shall be cast.
The materials of the label plates shall be as follows:
(a) Cast brass for historical data plate. (b) Aluminum alloy plates where mounted on aluminum alloy
structure. (c) All other plates brass.
The material of cast brass label plates shall be in accordance
with Navy Department Specifications 46B24. The material of
engraved and embossed brass plates shall be in accordance with
Navy Department Specifications 46B6. The material of aluminum alloy plates shall be in accordance with Navy Department
Specifications 47A11 or 47A12.
Cast plates shall be as thin as consistent with good casting, and
the figures and letters shall be raised and clearly defined. Engraved plates shall be 0.05 inch thick and the figures and letters
shall be clearly cut. Embossed plates shall be as heavy as can
be satisfactorily embossed. All label plates shall have smooth
edges. Tag label plates shall have smooth edges and round
corners to prevent injury to personnel. The figures and letters on
engraved plates shall be cut to a depth of 0.02 inch and filled in
with baked nitrocellulose enamel applied in a sufficient number
of coats to fill the figures and letters practically flush with the
surface of the plate. The enamel shall be black, except as otherwise specified.
Engraved brass plates shall be polished and not painted. Engraved aluminum alloy plates shall be given a coat of spar varnish.
Embossed plates shall be painted and the figures and letters
touched up with black paint.
Except where subject to mechanical injury, embossed plates
may be used for the following:
(a) Compartment and door label plates as required by section
5 herein. (b) Frame numbers as required by section 8 herein. (c) Bulkhead numbers as required by section 9 herein.
9
(d) Capacity, gage, and working-load plates, as required by
section 11 herein. (e) Ventilation blowers, their trunks, ducts, and louvers as
required by section 15 herein, except the label plates supplied by
the manufacturers. (f) Lockers, as required by section 17 herein. (g) Miscellaneous purposes as approved by the superintending
constructor.
In general other label plates shall be of the engraved type.
The combination of engraved plates and embossed plates in the
same group of label plates shall be avoided.
A sample plate of each type of label plates shall be finished and
secured to a metal bulkhead for approval by the superintending
constructor before proceeding with the work on the other plates.
All plates shall be so located that the inscriptions are readily
discernible. Where placed on one side only of a beam, they shall,
where practicable, be on the after side in the forward part of the
vessel and on the forward side in the after part of the vessel. When
located on a beam, the lower edge of the plate shall be as near
the lower edge of the beam as practicable, and when on a bulkhead the plate shall be located in the most suitable place for the
purpose, as, for example, plates referring to deck plates or valves,
the plate shall be placed about 12 inches above the deck. or about
3 inches above the face of the handle when the valve is open.
Plates found on completion to be obscured by curtains, rods,
pipes, furniture, or other fittings shall be relocated.
When special locations for label plates are necessary they shall
be as approved by the superintending constructor.
Where necessary to group several compartment label plates
over a hatch or door to indicate that access to the several compartments is through the hatch or door, the inscriptions shall be
placed one above the other where they indicate compartments
on different deck levels, the upper inscription denoting the upper
compartment, and placed on the same horizontal line when they
denote compartments on the same deck level, port, starboard, or
center, according to the location of the compartment with reference to the center line of the door or hatch.
These instructions describe in general the arrangements for
labeling on shipboard, but additional label plates, tags, etc., of
design to suit the conditions necessary fully to describe any object
or place, or its function in preparing the vessel for action, or to
give any special directions considered necessary in handling and
oiling apparatus and machinery, shall be made and fitted as
required by the superintending constructor.
10
The color of piping shall be in accordance with General Specifications, Appendix 6-Instructions for painting and Cementing
Vessels of the United States Navy.

Additional abbreviations may be used on inscriptions as
recommended by the superintending constructor and approved
by the bureau. Care shall be exercised, however, to insure that
such abbreviations are reasonably self-explanatory. A complete
list of all abbreviations used in labeling, including abbreviations
additional to those previously listed, shall be compiled and
included in the vessel's damage control book.
Abbreviated words shall be followed by a period.
For abbreviations used in compartment numbering, see chapter 2.
3. SIZE OF LETTERS AND PLATES.
Letters and figures shall generally be as large as the length of
the inscription, the location and means of securing the plate,
and other considerations permit, provided, however, that except
in very special cases, the letters and figures shall not be greater
than one inch, nor less than 1/4 inch, in height. For long inscriptions, the sizes of the letters and figures shall be as large as
11
consistent with a satisfactorily legible label plate in the location
concerned, and unusual care shall be exercised in determining the
arrangement so that the most important information contained
in the label, or that most frequently referred to, shall be in letters
sufficiently large to be easily read; the remainder of the lettering
may be reduced to suit the limitations of the plate size, but the
minimum height of such reduced lettering shall be 1/4 inch.
The same size of label plate or tag for each group of subjects
shall be maintained as far as practicable.
The lines of letters and figures shall be symmetrically arranged
with reference to the upper and lower edges of the plates or tags,
and to each other when there is more than a single line.
4. SECURING.
Label plates shall be secured by round-head machine screws, by
rivets or by round-head wood screws. Machine screws shall be
used for securing to metal where the thickness will permit. Rivets
shall be used where the thickness of the metal is not sufficient for
machine screws. Wood screws shall be used for securing to wood.
Brass fastenings shall be used for brass plates and corrosion-resisting steel fastenings or aluminum rivets for aluminum label
plates.
In securing the label plates to outside plating and to oiltight
or watertight structure, care shall be taken to avoid piercing the
structure with the means of securing; namely, the hole for the
machine screw shall not pierce the structure. Where this is
impracticable on light metal tight structure, the plate may be
drilled through provided the point of the screw is peened over.
The center of the holes for the securing screws or rivets shall be
in the middle of the width of the label plate and about 1/4 inch
from the end. If necessary to secure long embossed plates rigidly,
two additional screws or rivets shall be added at the center of
the plate, one at top and one at bottom, or one in the middle of
the plate if interference with the numbers or letters is not caused
thereby. Care shall be taken that the heads of the screws or
rivets do not cover any part of a number or figure. They shall
be 1/8 inch clear of all figures and letters.
Label plates mounted on corrugated bulkheads or wire-mesh
or expanded metal bulkheads shall be backed up with a metal
strip.
The brass label plates shall be set in red lead. The back of
aluminum alloy label plates shall be coated with zinc chromate
iron oxide paint.
12
5. COMPARTMENTS. DOORS, HATCHES, AND MANHOLES.
Compartment numbering shall be in accordance with the scheme
outlined in chapter 2. The label plates shall be located, as far
as practicable, to clearly indicate the compartment being entered.
The inscription shall give the door, hatch, or manhole number
and compartment description and number. Door, hatch, and
manhole number plates shall be combined with compartment
plates and, whenever possible, with capacity plates.
Except as otherwise specified, labels on doors and hatches shall
designate only the compartment to be entered. In the case of
hatches the labels shall designate only the space below.
The label on a hatch or door opening into a trunk from which
a number of compartments have access shall designate all such
compartments. Similarly, the labels on hatches or doors so
located in the normal access route that they serve as points of
departure for access to a number of compartments normally
kept locked, such as storerooms, shall designate all compartments
so served.
The first line of the inscription shall give only the number of
the hatch, door, or manhole. On the line below shall be given
the compartment designation to which the door gives access, and
en the third line shall be the compartment number, for example:
4-16-2
C.P.O. Stores
A-412
From the above it will be noted that the door, hatch, or manhole
number will consist of two or three parts, separated by hyphens.
In this paragraph the term "door" includes hatches and manholes.
The first part corresponding to the deck number as given in chapter
2; the next part the frame number just forward of the hinge of the
door, and the last part the number of the door, if there is more than
one door on the same frame on the deck designated by the first
part; if not, the third part may be omitted. For the first part of
their numbers, hatches and manholes shall take the number of
the deck through which they are cut. Odd numbers shall be used
in the third part for doors located on the starboard side and even
numbers on the port side. For example:
Door 3-24-1, is on the third deck, frame 24, or between frames
24 and 25, starboard side.
Door 3-24-2, is on the third deck, frame 24, or between frames
24 and 25,port side.
Hatch 3-24-2, is in the third deck at or immediately aft of
frame 24 on the port side.
13
Door, hatch, manhole, and compartment plates, either combined or single, shall be located on the door, hatch, or manhole
cover, except as noted below and shall be located as follows:
Hinged doors-12 inches from upper edge of plate to top of
door at center.
Small doors into trunks, wing passages, etc.-6 inches from
upper edge of plate to top of door at center.
Hatches-6 inches from side opposite the hinges to nearest
edge of plate.
Manholes-as convenient.
Where a hatch or manhole forms the access to a single compartment and the cover hinges against a bulkhead, the label plates
shall be installed on the bulkhead just above the cover when it is
hinged up, so that the label can be read with the cover either in
the open or closed position. Where a hatch or manhole forms
the access to a single compartment and the cover does not hinge
against a bulkhead, the label plates shall he fitted on the top side
of the cover.
Compartment plates for companionways shall be located on the
inside of the hatch coaming opposite the ladder or ladder rungs.
In special cases where doors, hatches, or manholes give access to
nontight or unimportant compartments, the plates may be
omitted altogether, or may contain the door, hatch, or manhole
number only, if approved by the superintending constructor.
Covers for all access manholes and hatches to fuel-oil tanks and
to gasoline-tank compartments shall be painted red.
A large distinctive type of label plate shall be fitted in the
vicinity of each watertight door through which portable trolley
tracks extend. The inscription on this label plate shall be:
"THE PORTABLE SECTION OF THIS TROLLEY TRACK
IS NOT TO BE LEFT ERECTED WHEN NOT IN USE."
In-addition to label plates, there shall be painted in a conspicuous place on a bulkhead in each tight compartment the
number of the compartment, prefixed by letter designating
the division of the compartment, as A-412. The letters and
figures shall be 2 inches high, and they shall be painted on a rectangular background of different color from that of the bulkhead.
6. CLOSURE CLASSIFICATION LABEL PLATES FOR ACCESS
OPENINGS.
In addition to the identification label plates, closure classification label plates shall be provided for all access openings in compartmentation boundaries, such as doors, hatches, manholes,
scuttles, and skylights, except bolted plate manholes.
A closure classification label plate shall also be provided for each
armored door, armored hatch, and ammunition hoist cover.
944557 O-51-3
14
These label plates shall be 4 inches square where it is practicable to fit this size plate; otherwise the plates may be reduced
in size, but it is desired to keep the plate as near 4 inches square as
mounting space will permit.
These plates shall be provided only with a single plain block
letter 3 inches in height for the four inch size plate. They shall be
engraved with the letters X, Y, Z, V, or W. The particular designating letter to be used in each case shall be determined by the
superintending constructor in consultation with the prospective
commanding officer of the vessel concerned. A list, giving the
location of the access openings with their classification letters
shall be forwarded to the Bureau for approval. The significance
of these letters is as follows:
X=Closed at all times except during periods of inspection or continuous use.
Y=Closed outside of working hours.
Z=Closed in action or emergency.
V=Closed at all times during wartime cruising.
W=Open during action.
The X, Y, V, and W plates shall have black letters; the Z plates
shall have red letters.
The label plates shall be secured to the closure part of the opening, one plate being provided for each side of the door or cover so
that the plate will be visible from both sides of the door and
visible when the cover is closed and opened.
Closure classification labels for manholes need be fitted only on
the side of the closed cover visible from outside the space to which
the manhole gives access.
Closure classification labels shall be provided for, and fitted to,
the closures of all miscellaneous openings which affect the compartmentation of the vessel.
7. STATEROOMS.
All staterooms shall be numbered. The numbers shall be in the
same hundred series as the compartment numbers on the deck on
which the staterooms are located. The numbers for staterooms

Identification labels for the foregoing systems and fittings shall
conform to the requirements of sections 1 to 4, subject to the
following interpretation:
The labels shall be installed to insure maximum visibility of
the inscription, consistent with economical installation, due consideration being given to the influence exerted by the size of the
label. The following methods of installation are approved; their
relative desirability is in the order listed:
1. Label plates secured to a bulkhead, hatch coaming, ship's
side, or other structure where unmistakable identification can
thereby be assured.
2. Inscription engraved or stamped on the rim of the hand
wheel; a portion of the rim may be finished smooth for this
purpose.
3. Label plates secured to the valve wheel or operating lever.
4. Label plates attached to the valve flange or the flange
stamped with the inscription.
5. Tag labels securely wired to the valve stem or operating

The inscriptions on deck plates for sounding tubes and valve
operating gear shall be in accordance with the latest issue of the
Bureau's Standard plan C. & R. No. 120775 or superseding plan,
modified to the extent that the inscription shall include the valve
number us hereinafter described. In addition to the deck plate, a
supplementary plate shall be provided on the bulkhead or beam
nearest to or over the deck plate, carrying an inscription identical
to that on the deck plate.
20
Manifold labels shall be located on the bulkhead over the center
of the group of valves, and just above the valve label plates.
Where there is no bulkhead adjoining, the manifold plates shall
be located on the manifold box or box casing in a manner approved
by the superintending constructor. The plates shall be similar to
sketch D. In addition to the manifold label, each valve in the
manifold shall be labeled.
SKETCH D
For valves with wheels located beneath the floor plates, a label
plate repeating the label on the valve shall be set into the top of
the floor plate close to the cover giving access to the valve.
Piping system identification labels shall be in accordance with
the following provisions where applicable:
(a) The inscription shall indicate specifically the designation of
the fitting, as, for examples:
"Fire Main Cutout."
"3,000-Pound Air Main Cross-Connection."
"Drain Bulkhead Stop "
"Drain B-1."
(b) The inscription shall contain the number of the fitting
where such numbering is hereinafter required. The number shall
be determined in accordance with the scheme for numbering
doors, section 5. The number shall consist of two or three parts,
the first part indicating the number of the deck, the second part
the frame number, and the third part, if necessary, a serial number
to differentiate between two or more similar fittings in the same
location.
(c) The numbers which are assigned to valves and fittings in
voids, tanks, and other spaces habitually closed, shall be determined by the location of the distant control gear nearest the valve
or fitting from which it is normally operated. The valve in this
case shall be assigned the number as determined for this operating
station. The numbers for all valves not in voids, tanks, or spaces
habitually kept closed shall be determined from the location of
the valve itself ; in other words, from the point where the valve
is normally operated. In this case, the distant operating station,
if any, shall carry the number as so determined by the location
of the valve.
(d) Fittings in each system shall be numbered without respect
to fittings in other systems; that, is, there may be a number of
21
valves carrying the same number, but the valves will be differentiated by the designation required under (a) above.
Fittings which serve no particular compartment, such as a
fire main riser cut out valve, or a compressed air bulkhead stop
valve, shall be labeled with identifying name and number only.
Identification numbers will not be assigned the following:
Sounding tubes, air escapes, and filling connections particular
care shall be taken, however, to insure that identification of such
fittings is completely indicated by the label.
Subject to the foregoing limitations, all fittings requiring a
label, which serve a particular compartment, shall be labeled to
indicate the compartment served.
The arrangement of piping identification labels shall generally
be as follows:
(1) The function or distinguishing name of the fitting.
(2) The compartment served.
(3) The number of the fitting.
Voice tube numbers shall be assigned serially in accordance
with the voice tube list, each number bearing the prefix "VT" instead of the composite number above described. Each voice tube
shall be labeled at least once in each compartment through
which it passes, with a tag permanently secured to the tube in
such a manner that the tube can be readily identified. At the
outlets, labels shall be fitted both on the inside and outside of the
cover, so that the tube number and the station to which the voice
tube leads will be clearly shown at all times. Where such label
plates may be installed close to and above the mouthpiece in
such a manner that the voice tube can be readily identified
whether open or shut, it will not be necessary to install labels on
the cover proper.
Labels on cutout valves in gas ejecting and gun rammer air
systems shall indicate the serial numbers of the guns served.
Each fireplug label shall indicate the number of the cutout valve
serving that particular fireplug. The following examples illustrate the application of the above requirements:
FIREPLUG 3-40-1
CUTOUT 5-46
This label indicates a fireplug on the deck or platform on which
the compartments are numbered in the 300 series, and at frame
40; that there is more than one fireplug on this deck in this frame
space, and that the one in question is on the starboard side. This
label also indicates that this fireplug is served through a riser cutout located on the deck or platform on which the compartments
are numbered in the 500 series, and at frame 46. It should be
22
noted that the name "fireplug" is essential to the label in order
to differentiate fireplug from cutout valves.
F. O. SUC. B-85
3-76-1
This label indicates a fuel oil suction valve from fuel oil tank
B-85F, the valve being normally operable from a station on the
third deck at frame 76 on the starboard side. The valve in this
example is in the inner void of a battleship. The label in question
shall be put on the valve as wall as on the operating gear.
SOUND C-905F
This indicates a sounding station for fuel oil tank C-905. No
number is assigned to this fitting in accordance with the foregoing requirements.
FLOOD MAG. A-408
4-37-2
This indicates a magazine flood for compartment A-408M, which
valve is located on the deck or platform on which the compartments are numbered in the 400 series and at frame 37port side.
This label shall be fitted on the valve, on the deck plate, and in the
vicinity of the deck plate as previously required.
