Notes: To be applied to tables 26.1 to 26.4, as appropriate.
a Where adjacent spaces are in the same numerical category and
superscript a appears, a bulkhead or deck between such spaces need not be
fitted if deemed unnecessary by the Administration. For example, in
category (12) a bulkhead need not be required between a galley and its
annexed pantries provided the pantry bulkheads and decks maintain the
integrity of the galley boundaries. A bulkhead is, however, required
between a galley and a machinery space even though both spaces are in
category (12).
b Where superscript b appears the lesser insulation value may be
permitted only if at least one of the adjoining spaces is protected by an
automatic sprinkler system complying with the provisions of Regulation 12.
Regulation 27 Fire integrity of bulkheads and decks in ships car-rying not more than 36 passengers
1 In addition to complying with the specific provisions for fire
integrity of bulkheads and decks mentioned elsewhere in this Part, the
minimum fire integrity of bulkheads and decks shall be as prescribed in
table 27.1 and table 27.2.
2 The following requirements shall govern application of the tables:
.1 Tables 27.1 and 27.2 shall apply respectively to the bulkheads
and decks separating adjacent spaces.
.2 For determining the appropriate fire integrity standards to be
applied to divisions between adjacent spaces, such spaces are classified
according to their fire risk as shown in categories (1) to (11) below. The
title of each category is intended to be typical rather than restrictive.
The number in parentheses preceding each category refers to the applicable
column or row in the tables.
(1) Control stations
Spaces containing emergency sources of power and lighting.
Wheelhouse and chartroom.
Spaces containing the ship's radio equipment.
Fire-extinguishing rooms, fire control stations and
fire-recording stations.
Control room for propulsion machinery when located outside
the machinery space.
Spaces containing centralized fire alarm equipment.
(2) Corridors
Passenger and crew corridors and lobbies.
(3) Accommodation spaces
Spaces as defined in Regulation 3.10 excluding corridors.
(4) Stairways
Interior stairways, lifts and escalators (other than those
wholly contained within the machinery spaces) and enclosures thereto.
In this connexion, a stairway which is enclosed only at
one level shall be regarded as part of the space from which it is not
separated by a fire door.
(5) Service spaces (low risk)
Lockers and store-rooms having areas of less than 2 square
m , drying rooms and laundries.
(6) Machinery spaces of category A
Spaces as defined in Regulation 3.19.
(7) Other machinery spaces
Spaces as defined in Regulation 3.20 excluding machinery
spaces of category A.
(8) Cargo spaces
All spaces used for cargo (including cargo oil tanks) and
trunkways and hatchways to such spaces, other than special category
spaces.
(9) Service spaces (high risk)
Galleys, pantries containing cooking appliances, paint and
lamp rooms, lockers and store-rooms having areas of 2 square m or more and
workshops other than those forming part of the machinery spaces.
(10) Open decks
Open deck spaces and enclosed promenades having no fire
risk. Air spaces (the space outside superstructures and deckhouses).
(11) Special category spaces
Spaces as defined in Regulation 3.18.
.3 In determining the applicable fire integrity standard of a
boundary between two spaces within a main vertical zone or horizontal zone
which is not protected by an automatic sprinkler system complying with the
provisions of Regulation 12 or between such zones neither of which is so
protected, the higher of the two values given in the tables shall apply.
.4 In determining the applicable fire integrity standard of a
boundary between two spaces within a main vertical zone or horizontal zone
which is protected by an automatic sprinkler system complying with the
provisions of Regulation 12 or between such zones both of which are so
protected, the lesser of the two values given in the tables shall apply.
Where a sprinklered zone and a non-sprinklered zone meet within
accommodation and service spaces, the higher of the two values given in
the tables shall apply to the division between the zones.
3 Continuous "B" class ceilings or linings, in association with the
relevant decks or bulkheads, may be accepted as contributing, wholly or
in part, to the required insulation and integrity of a division.
4 External boundaries which are required in Regulation 23.1 to be of
steel or other equivalent material may be pierced for the fitting of
windows and sidescuttles provided that there is no requirement for such
boundaries to have "A" class integrity elsewhere in this Chapter.
Similarly, in such boundaries which are not required to have "A" class
integrity, doors may be of materials to the satisfaction of the
Administration.

Regulation 28 Means of escape
1 Stairways and ladders shall be arranged to provide ready means of
escape to the lifeboat and liferaft embarkation deck from all passenger
and crew spaces and from spaces in which the crew is normally employed,
other than machinery spaces. In particular, the following provisions shall
be complied with:
.1 Below the bulkhead deck two means of escape, at least one of
which shall be independent of watertight doors, shall be provided from
each watertight compartment or similarly restricted space or group of
spaces. Exceptionally, the Administration may dispense with one of the
means of escape, due regard being paid to the nature and location of
spaces and to the number of persons who might normally be accommodated or
employed there.
.2 Above the bulkhead deck there shall be at least two means of
escape from each main vertical zone or similarly restricted space or group
of spaces at least one of which shall give access to a stairway forming a
vertical escape.
.3 If a radiotelegraph station has no direct access to the open
deck, two means of escape from or access to such station shall be
provided, one of which may be a porthole or window of sufficient size or
another means to the satisfaction of the Administration.
.4 A corridor or part of a corridor from which there is only one
route of escape shall not exceed:
13 m in length for ships carrying more than 36 passengers, and
7 m in length for ships carrying not more than 36 passengers.
.5 At least one of the means of escape required by paragraphs 1.1
and 1.2 shall consist of a readily accessible enclosed stairway, which
shall provide continuous fire shelter from the level of its origin to the
appropriate lifeboat and liferaft embarkation decks or the highest level
served by the stairway, whichever level is the highest. However, where
the Administration has granted dispensation under the provisions of
paragraph 1.1 the sole means of escape shall provide safe escape to the
satisfaction of the Administration. The width, number and continuity of
the stairways shall be to the satisfaction of the Administration.
.6 Protection of access from the stairway enclosures to the
lifeboat and liferaft embarkation areas shall be to the satisfaction of
the Administration.
.7 Stairways serving only a space and a balcony in that space
shall not be considered as forming one of the required means of escape.
2.1 In special category spaces the number and disposition of the means
of escape both below and above the bulkhead deck shall be to the
satisfaction of the Administration and in general the safety of access to
the embarkation deck shall be at least equivalent to that provided for
under paragraphs 1.1, 1.2, 1.5 and 1.6.
2.2 One of the escape routes from the machinery spaces where the crew
is normally employed shall avoid direct access to any special category
space.
3.1 Two means of escape shall be provided from each machinery space.
In particular, the following provisions shall be complied with:
.1 Where the space is below the bulkhead deck the two means of
escape shall consist of either:
.1.1 two sets of steel ladders as widely separated as
possible, leading to doors in the upper part of the space similarly
separated and from which access is provided to the appropriate lifeboat
and liferaft embarkation decks. One of these ladders shall provide
continuous fire shelter from the lower part of the space to a safe
position outside the space; or
.1.2 one steel ladder leading to a door in the upper part of
the space from which access is provided to the embarkation deck and
additionally, in the lower part of the space and in a position well
separated from the ladder referred to, a steel door capable of being
operated from each side and which provides access to a safe escape route
from the lower part of the space to the embarkation deck.
.2 Where the space is above the bulkhead deck, the two means of
escape shall be as widely separated as possible and the doors leading from
such means of escape shall be in a position from which access is provided
to the appropriate lifeboat and liferaft embarkation decks. Where such
means of escape require the use of ladders, these shall be of steel.
3.2 In a ship of less than 1,000 tons gross tonnage, the
Administration may dispense with one of the means of escape, due regard
being paid to the width and disposition of the upper part of the space;
and in a ship of 1,000 tons gross tonnage and above, the Administration
may dispense with one means of escape from any such space so long as
either a door or a steel ladder provides a safe escape route to the
embarkation deck, due regard being paid to the nature and location of the
space and whether persons are normally employed in that space.
4 In no case shall lifts be considered as forming one of the required
means of escape.
Regulation 29 Protection of stairways and lifts in accommodationand service spaces
1 All stairways shall be of steel frame construction except where the
Administration sanctions the use of other equivalent material, and shall
be within enclosures formed of "A" class divisions, with positive means of
closure at all openings, except that:
.1 a stairway connecting only two decks need not be enclosed,
provided the integrity of the deck is maintained by proper bulkheads or
doors in one 'tweendeck space.
When a stairway is closed in one 'tweendeck space, the stairway
enclosure shall be protected in accordance with the tables for decks in
Regulations 26 or 27;
.2 stairways may be fitted in the open in a public space, provided
they lie wholly within such public space.
2 Stairway enclosures shall have direct communication with the
corridors and be of sufficient area to prevent congestion, having in view
the number of persons likely to use them in an emergency. In so far as is
practicable, stairway enclosures shall not give direct access to cabins,
service lockers, or other enclosed spaces containing combustibles in which
a fire is likely to originate.
3 Lift trunks shall be so fitted as to prevent the passage of smoke
and flame from one 'tweendeck to another and shall be provided with means
of closing so as to permit the control of draught and smoke.
Regulation 30 Openings in "A" class divisions
1 Except for hatches between cargo, special category, store, and
baggage spaces, and between such spaces and the weather decks, all
openings shall be provided with permanently attached means of closing
which shall be at least as effective for resisting fires as the divisions
in which they are fitted.
2 The construction of all doors and door frames in "A" class
divisions, with the means of securing them when closed, shall provide
resistance to fire as well as to the passage of smoke and flame, as far as
practicable, equivalent to that of the bulkheads in which the doors are
situated. Such doors and door frames shall be constructed of steel or
other equivalent material. Watertight doors need not be insulated.
3 It shall be possible for each door to be opened and closed from each
side of the bulkhead by one person only.
4 Fire doors in main vertical zone bulkheads and stairway enclosures,
other than power-operated watertight doors and those which are normally
locked, shall be of the self-closing type capable of closing against an
inclination of 3.5 ”ć opposing closure. The speed of door closure shall,
if necessary, be controlled so as to prevent undue danger to persons. All
such doors, except those that are normally closed, shall be capable of
release from a control station, either simultaneously or in groups, and
also individually from a position at the door. The release mechanism shall
be so designed that the door will automatically close in the event of
disruption of the control system; however, approved power-operated
watertight doors will be considered acceptable for this purpose. Hold-back
hooks not subject to control station release will not be permitted. When
double swing doors are permitted, they shall have a latch arrangement
which is automatically engaged by the operation of the door release
system.
5 Where a space is protected be an automatic sprinkler system
complying with the provisions of Regulation 12 or fitted with a continuous
"B" class ceiling, openings in decks not forming steps in main vertical
zones nor bounding horizontal zones shall be closed reasonably tight and
such decks shall meet the "A" class integrity requirements in so far as is
reasonable and practicable in the opinion of the Administration.
6 The requirements for "A" class integrity of the outer boundaries of
a ship shall not apply to glass partitions, windows and sidescuttles.
Similarly, the requirements for "A" class integrity shall not apply to
exterior doors in superstructures and deckhouses.
Regulation 31 Openings in "B" class divisions
1 Doors and door frames in "B" class divisions and means of securing
them shall provide a method of closure which shall have resistance to fire
as far as practicable equivalent to that of the divisions except that
ventilation openings may be permitted in the lower portion of such doors.
Where such opening is in or under a door the total net area of any such
opening or openings shall not exceed 0.05 square m . When such opening is
cut in a door it shall be fitted with a grill made of non-combustible
material. Doors shall be non-combustible.
2 The requirements for "B" class integrity of the outer boundaries of
a ship shall not apply to glass partitions, windows and sidescuttles.
Similarly, the requirements for "B" class integrity shall not apply to
exterior doors in superstructures and deckhouses. For ships carrying not
more than 36 passengers, the Administration may permit the use of
combustible materials in doors separating cabins from the individual
interior sanitary spaces such as showers.
3 Where an automatic sprinkler system complying with the provisions of
Regulation 12 is fitted:
.1 openings in decks not forming steps in main vertical zones nor
bounding horizontal zones shall be closed reasonably tight and such decks
shall meet the "B" class integrity requirements in so far as is reasonable
and practicable in the opinion of the Administration; and
.2 openings in corridor bulkheads of "B" class materials shall be
protected in accordance with the provisions of Regulation 25.
Regulation 32 Ventilation systems
1 Passenger ships carrying more than 36 passengers
1.1 The ventilation system of a passenger ship carrying more than 36
passengers shall, in addition to this part of this Regulation, also be in
compliance with the requirements of Regulation 16.2 to 16.9.
1.2 In general, the ventilation fans shall be so disposed that the
ducts reaching the various spaces remain within the main vertical zone.
1.3 Where ventilation systems penetrate decks, precautions shall be
taken, in addition to those relating to the fire integrity of the deck
required by Regulations 18.1.1 and 30.5, to reduce the likelihood of smoke
and hot gases passing from one 'tweendeck space to another through the
system. In addition to insulation requirements contained in this
Regulation, vertical ducts shall, if necessary, be insulated as required
by the appropriate tables in Regulation 26.
1.4 Except in cargo spaces, ventilation ducts shall be constructed of
the following materials:
.1 ducts not less than 0.075 square m in sectional area and all
vertical ducts serving more than a single 'tweendeck space shall be
constructed of steel or other equivalent material;
.2 ducts less than 0.075 square m in sectional area other than the
vertical ducts referred to in paragraph 1.4.1, shall be constructed of
non-combustible materials. Where such ducts penetrate "A" or "B" class
divisions due regard shall be given to ensuring the fire integrity of the
division;
.3 short lengths of duct, not in general exceeding 0.02 square m
in sectional area nor 2 m in length, need not be non-combustible provided
that all of the following conditions are met:
.3.1 the duct is constructed of a material of restricted fire
risk to the satisfaction of the Administration;
.3.2 the duct is used only at the terminal end of the
ventilation system; and
.3.3 the duct is not located closer than 600 mm measured along
its length to a penetration of an "A" or "B" class division, including
continuous "B" class ceilings.
1.5 Where a stairway enclosure is ventilated, the duct or ducts shall
be taken from the fan room independently of other ducts in the ventilation
system and shall not serve any other space.
1.6 All power ventilation, except machinery space and cargo space
ventilation and any alternative system which may be required under
Regulation 16.6, shall be fitted with controls so grouped that all fans
may be stopped from either of two separate positions which shall be
situated as far apart as practicable. Controls provided for the power
ventilation serving machinery spaces shall also be grouped so as to be
operable from two positions, one of which shall be outside such spaces.
Fans serving power ventilation systems to cargo spaces shall be capable of
being stopped from a safe position outside such spaces.
2 Passenger ships carrying not more than 36 passengers
2.1 The ventilation system of passenger ships carrying not more than
36 passengers shall be in compliance with Regulation 16.
Regulation 33 Windows and sidescuttles
1 All windows and sidescuttles in bulkheads within accommodation and
service spaces and control stations other than those to which the
provisions of Regulation 30.6 and of Regulation 31.2 apply, shall be so
constructed as to preserve the integrity requirements of the type of
bulkheads in which they are fitted.
2 Notwithstanding the requirements of the tables in Regulations 26 and
27:
.1 all windows and sidescuttles in bulkheads separating
accommodation and service spaces and control stations from weather shall
be constructed with frames of steel or other suitable material. The glass
shall be retained by a metal glazing bead or angle;
.2 special attention shall be given to the fire integrity of
windows facing open or enclosed lifeboat and liferaft embarkation areas
and to the fire integrity of windows situated below such areas in such a
position that their failure during a fire would impede the launching of,
or embarkation into, lifeboats, or liferafts.
Regulation 34 Restricted use of combustible materials
1 Except in cargo spaces, mail rooms, baggage rooms, or refrigerated
compartments of service spaces, all linings, grounds, ceilings and
insulations shall be of non-combustible materials. Partial bulkheads or
decks used to subdivide a space for utility or artistic treatment shall
also be of non-combustible material.
2 Vapour barriers and adhesives used in conjunction with insulation,
as well as insulation of pipe fittings, for cold service systems need not
be non-combustible, but they shall be kept to the minimum quantity
practicable and their exposed surfaces shall have qualities of resistance
to the propagation of flame to the satisfaction of the Administration.
3 The following surfaces shall have low flame-spread characteristics:
*
[* Reference is made to Guidelines on the Evaluation of Fire Hazard
Properties of Materials, adopted by the Organization by resolution A. 166
(ES.IV).]
.1 exposed surfaces in corridors and stairway enclosures, and of
bulkheads, wall and ceiling linings in all accommodation and service
spaces and control stations;
.2 concealed or inaccessible spaces in accommodation, service
spaces and control stations.
4 The total volume of combustible facings, mouldings, decorations and
veneers in any accommodation and service space shall not exceed a volume
equivalent to 2.5 mm veneer on the combined area of the walls and
ceilings. In the case of ships fitted with an automatic sprinkler system
complying with the provisions of Regulation 12, the above volume may
include some combustible material used for erection of "C" class
divisions.
5 Veneers used on surfaces and linings covered by the requirements of
paragraph 3 shall have a calorific value not exceeding 45 MJ/square m of
the area for the thickness used.
6 Furniture in the corridors and stairway enclosures shall be kept to
a minimum.
7 Paints, varnishes and other finishes used on exposed interior
surfaces shall not be capable of producing excessive quantities of smoke
and toxic products.
8 Primary deck coverings, if applied within accommodation and service
space and control stations, shall be of approved material which will not
readily ignite, or give rise to toxic or explosive hazards at elevated
temperatures. *
[* Reference is made to Improved/Provisional/Guidelines on Test
Procedures for Primary Deck/Coverings, adopted by the Organization by
resolution A. 214(VII).]
Regulation 35 Details of construction
1 In accommodation and service spaces, control stations, corridors and
stairways:
.1 air spaces enclosed behind ceilings, panelling or linings shall
be suitably divided by close-fitting draught stops not more than 14 m
apart;
.2 in the vertical direction, such enclosed air spaces, including
those behind linings stairways, trunks, etc. shall be closed at each deck.
2 The construction of ceiling and bulkheads shall be such that it will
be possible, without impairing the efficiency of the fire protection, for
the fire patrols to detect any smoke originating in concealed and
inaccessible places, except where in the opinion of the Administration
there is no risk of fire originating in such places.
Regulation 36 Automatic sprinkler, fire detection and fire alarmsystems or automatic fire detection and fire alarm systems
1 In any ship to which this Part applies there shall be installed
throughout each separate zone, whether vertical or horizontal, in all
accommodation and service spaces and, where it is considered necessary by
the Administration, in control stations, except spaces which afford no
substantial fire risk (such as void spaces, sanitary spaces, etc.) either:
.1 an automatic sprinkler, fire detection and fire alarm system of
an approved type, complying with the provisions of Regulation 12 and so
installed and arranged as to protect such spaces; or
.2 a fixed fire detection and fire alarm system of an approved
type, complying with the provisions of Regulation 13 and so installed and
arranged as to detect the presence of fire in such spaces, except that the
smoke detectors required by Regulation 13.2. 2 need not be provided.
Regulation 37 Protection of special category spaces
1 Provisions applicable to special category spaces whether above or
below the bulkhead deck
1.1 General
1.1.1 The basic principle underlying the provisions of this Regulation
is that as normal main vertical zoning may not be practicable in special
category spaces, equivalent protection must be obtained in such spaces on
the basis of a horizontal zone concept and by the provision of an
efficient fixed fire-extinguishing system. Under this concept a horizontal
zone for the purpose of this Regulation may include special category
spaces on more than one deck provided that the total overall clear height
for vehicles does not exceed 10 m.
1.1.2 The requirements of Regulations 16, 18, 30 and 32 for
maintaining the integrity of vertical zones shall be applied equally to
decks and bulkheads forming the boundaries separating horizontal zones
from each other and from the remainder of the ship.

1,000 tons gross tonnage and upwards shall be protected by affixed gas
fire-extinguishing system complying with the provisions of Regulation 5,
or by a fixed high expansion foam fire-extinguishing system which gives
equivalent protection.
2 Where it is shown to the satisfaction of the Administration that a
ship is engaged on voyages of such short duration that it would be
unreasonable to apply the requirements of paragraph 1 and also in ships of
less than 1,000 tons gross tonnage, the arrangements in cargo spaces shall
be to the satisfaction of the Administration.
3 A ship engaged in the carriage of dangerous goods shall be provided
in any cargo spaces with a fixed gas fire-extinguishing system complying
with the provisions of Regulation 5 or with a fire-extinguishing system
which in the opinion of the Administration gives equivalent protection for
the cargoes carried.

1 Manual alarms shall be fitted throughout the accommodation and
service spaces to transmit an alarm immediately to the navigating bridge
or main fire control station.
2 An approved fire detection or fire alarm system shall be provided
which will automatically indicate at one or more suitable points or
stations the presence or indication of fire and its location in any cargo
space which, in the opinion of the Administration, is not accessible
except where it is shown to the satisfaction of the Administration that
the ship is engaged on voyages of such short duration that it would be
unreasonable to apply this requirement.
3 All ships shall at all times when at sea, or in port (except when
out of service), be so manned or equipped as to ensure that any initial
fire alarm is immediately received by a responsible member of the crew.
4 A special alarm, operated from the navigating bridge or fire control
station, shall be fitted to summon the crew. This alarm may be part of the
ship's general alarm system but it shall be capable of being sounded
independently of the alarm to the passenger spaces.
5 A public address system or other effective means of communication
shall be available throughout the accommodation and service spaces and
control stations.
6 For ships carrying more than 36 passengers an efficient patrol
system shall be maintained so that an outbreak of fire may be promptly
detected. Each member of the fire patrol shall be trained to be familiar
with the arrangements of the ship as well as the location and operation of
any equipment he may be called upon to use.
Regulation 41 Special requirements for ships carrying dangerousgoods
The requirements of Regulation 54 shall apply, as appropriate, to
passenger ships carrying dangerous goods.
PART C FIRE SAFETY MEASURES FOR CARGO SHIPS
(Regulation 54 of this Part also applies to passenger ships as
appropriate).
Regulation 42 Structure
1 Subject to the provisions of paragraph 4, the hull, superstructure,
structural bulkheads, decks and deckhouses shall be constructed of steel
or other equivalent material.
2 The insulation of aluminium alloy components of "A" or "B" class
divisions, except structure which in the opinion of the Administration is
non-load-bearing, shall be such that the temperature of the structural
core does not rise more than 200”ę above the ambient temperature at any
time during the applicable exposure to the standard fire test.
3 Special attention shall be given to the insulation of aluminium
alloy components of columns, stanchions and other structural members
required to support lifeboat and liferaft stowage, launching and
embarkation areas, and "A" and "B" class divisions, to ensure:
.1 that for such members supporting lifeboat and liferaft areas
and "A" class divisions, the temperature rise limitation specified in
paragraph 2 shall apply at the end of one hour; and
.2 that for such members required to support "B" class divisions,
the temperature rise limitation specified in paragraph 2 shall apply at
the end of half an hour.
4 Crowns and casings of machinery spaces of category A shall be of
steel construction adequately insulated and openings therein, if any,
shall be suitably arranged and protected to prevent the spread of fire.
5 One of the following methods of protection shall be adopted in
accommodation and service areas:
.1 Method IC-The construction of all internal divisional
bulkheading of non-combustible "B" or "C" class divisions generally
without the installation of an automatic sprinkler, fire detection and
fire alarm system in the accommodation and service spaces, except as
required by Regulation 52.1; or
.2 Method IIC-The fitting of an automatic sprinkler, fire
detection and fire alarm system as required by Regulation 52.2 for the
detection and extinction of fire in all spaces in which fire might be
expected to originate, generally with no restriction on the type of
internal divisional bulkheading; or
.3 Method IIIC-The fitting of a fixed fire detection and fire
alarm system, as required by Regulation 52.3, in all spaces in which a
fire might be expected to originate, generally with no restriction on the
type of internal divisional bulkheading, except that in no case must the
area of any accommodation space or spaces bounded by an "A" or "B" class
division exceed 50 square m . Consideration may be given by the
Administration to increasing this area for public spaces.
6 The requirements for the use of non-combustible materials in
construction and insulation of the boundary bulkheads of machinery spaces,
control stations, service spaces, etc., and the protection of stairway
enclosures and corridors will be common to all three methods outlined in
paragraph 5.
Regulation 43 Bulkheads within the accommodation and servicespaces
1 All bulkheads required to be "B" class divisions shall extend from
deck to deck and to the shell or other boundaries, unless continuous "B"
class ceilings or linings are fitted on both sides of the bulkhead in
which case the bulkhead may terminate at the continuous ceiling or lining.
2 Method IC-All bulkheads not required by this or other Regulations of
this Part to be "A" or "B" class divisions, shall be of at least "C" class
construction.
3 Method IIC-There shall be no restriction on construction of
bulkheads not required by this or other Regulations of this Part to be "A"
or "B" class divisions except in individual cases where "C" class
bulkheads are required in accordance with table 44.1.
4 Method IIIC-There shall be no restriction on the construction of
bulkheads not required by this Part to be "A" or "B" class divisions
except that the area of any accommodation space or spaces bounded by a
continuous "A" or "B" class division must in no case
2 exceed 50 m except in individual cases where "C" class
bulkheads are required in accordance with table 44.1. Consideration may be
given by the Administration to increasing this area for public space.
Regulation 44 Fire integrity of bulkheads and decks
1 In addition to complying with the specific provisions for fire
integrity of bulkheads and decks mentioned elsewhere in this Part, the
minimum fire integrity of bulkheads and decks shall be as prescribed in
tables 44.1 and 44.2.
2 The following requirements shall govern application of the tables:
.1 Tables 44.1 and 44.2 shall apply respectively to the bulkheads
and decks separating adjacent spaces.
.2 For determining the appropriate fire integrity standards to be
applied to divisions between adjacent spaces, such spaces are classified
according to their fire risk as shown in categories (1) to (11) below. The
title of each category is intended to be typical rather than restrictive.
The number in parentheses preceding each category refers to the applicable
column or row in the tables.
(1) Control stations

Notes: To be applied to tables 44.1 and 44.2, as appropriate.
a) No special requirements are imposed upon bulkheads in methods IIC
and IIIC fire protection.
b) In case of method IIIC "B" class bulkheads of "B-0" rating shall be
provided between spaces or groups of spaces of 50 square m and over in
area.
c) For clarification as to which applies, see Regulations 43 and 46.
d) Where spaces are of the same numerical category and superscript d
appears, a bulkhead or deck of the rating shown in the tables is only
required when the adjacent spaces are for a different purpose, e.g. in
category (9). A galley next to a galley does not require a bulkhead but a
galley next to a paint room requires an "A-0" bulkhead.
e) Bulkheads separating the wheelhouse, chartroom and radio room from
each other may be "B-0" rating.
f) A-0 rating may be used if no dangerous goods are intended to be
carried or if such goods are stowed not less than 3 m horizontally from
such bulkhead.
g) For cargo spaces in which dangerous goods are intended to be
carried, Regulation 54.2.8 applies.
h) Bulkheads and decks separating ro/ro cargo spaces shall be capable
of being closed reasonably gastight and such divisions shall have "A"
class integrity in so far as is reasonable and practicable in the opinion
of the Administration.
i) Fire insulation need not be fitted if the machinery space in
category (7), in the opinion of the Administration, has little or no fire
risk.
* Where an asterisk appears in the tables, the division is required to
be of steel or other equivalent material but is not required to be of "A"
class standard.

trunkways and hatchways to such spaces.
(9) Service spaces (high risk)
Galleys, pantries containing cooking appliances, paint and
lamp rooms, lockers
and store-rooms having an area of 2 square m or more, workshops other
than those forming part of the machinery spaces.
(10) Open decks
Open deck spaces and enclosed promenades having no fire
risk. Air spaces (the space outside superstructures and deckhouses).
(11) Ro/ro cargo spaces
Spaces as defined in Regulation 3.14. Cargo spaces
intended for the carriage of motor vehicles with fuel in their tanks for
their own propulsion.
3 Continuous "B" class ceilings or linings, in association with the
relevant decks or bulkheads, may be accepted as contributing, wholly or
in part, to the required insulation and integrity of a division.
4 External boundaries which are required in Regulation 42.1 to be of
steel or other equivalent material may be pierced for the fitting of
windows and sidescuttles provided that there is no requirement for such
boundaries to have "A" class integrity elsewhere in this Part. Similarly,
in such boundaries which are not required to have "A" class integrity,
doors may be of materials to the satisfaction of the Administration.
Regulation 45 Means of escape
1 Stairways and ladders shall be so arranged as to provide, from all
accommodation spaces and from spaces in which the crew is normally
employed, other than machinery spaces, ready means of escape to the open
deck and thence to the lifeboats and liferafts. In particular the
following general provisions shall be complied with:
.1 At all levels of accommodation there shall be provided at least
two widely separated means of escape from each restricted space or group
of spaces.
.2.1 Below the lowest open deck the main means of escape shall be
a stairway and the second escape may be a trunk or a stairway.
.2.2 Above the lowest open deck the means of escape shall be
stairways or doors to an open deck or a combination thereof.
.3 Exceptionally the Administration may dispense with one of the
means of escape, due regard being paid to the nature and location of
spaces and to the numbers of persons who normally might be quartered or
employed there.
.4 No dead-end corridors having a length of more than 7 m shall be
accepted. A dead-end corridor is a corridor or part of a corridor from
which there is only one escape route.
.5 The width and continuity of the means of escape shall be to the
satisfaction of the Administration.
.6 In a radiotelegraph station has no direct access to the open
deck, two means of access to or egress from such station shall be
provided, one of which may be a porthole or window of sufficient size or
other means to the satisfaction of the Administration, to provide an
emergency escape.
2. In all ro/ro cargo spaces where the crew is normally employed the
number and locations of escape routes to the open deck shall be to the
satisfaction of the Administration, but shall in no case be less than two
and shall be widely separated.
3 Except as provided in paragraph 4, two means of escape shall be
provided from each machinery space of category A. In particular, one of
the following provisions shall be complied with:
.1 two sets of steel ladders as widely separated as possible
leading to doors in the upper part of the space similarly separated and
from which access is provided to the open deck. In general, one of these
ladders shall provide continuous fire shelter from the lower part of the
space to a safe position outside the space. However, the Administration
may not require the shelter if, due to the special arrangement or
dimensions of the machinery space, a safe escape route from the lower part
of this space is provided. This shelter shall be of steel, insulated,
where necessary, to the satisfaction of the Administration and be provided
with a self-closing steel door at the lower end; or
.2 one steel ladder leading to a door in the upper part of the
space from which access is provided to the open deck and additionally, in
the lower part of the space and in a position well separated from the
ladder referred to, a steel door capable of being operated from each side
and which provides access to a safe escape route from the lower part of
the space to the open deck.
4 In a ship of less than 1,000 tons gross tonnage, the Administration
may dispense with one of the means of escape required under paragraph 3,
due regard being paid to the dimension and disposition of the upper part
of the space.
5 From machinery spaces other than those of category A, escape routes
shall be provided to the satisfaction of the Administration having regard
to the nature and location of the space and whether persons are normally
employed in that space.
6 Lifts shall not be considered as forming one of the required means
of escape as required by this Regulation.
Regulation 46 Protection of stairways and lift trunks in accommo-dation spaces, service spaces and control stations
1 Stairways which penetrate only a single deck shall be protected at
least at one level by at least "B-0" class divisions and self-closing
doors. Lifts which penetrate only a single deck shall be surrounded by
"A-0" class divisions with steel doors at both levels. Stairways and lift
trunks which penetrate more than a single deck shall be surrounded by at
least "A-0" class divisions and be protected by self-closing doors at all
levels.
2 On ships having accommodation for 12 persons or less, where
stairways penetrate more than a single deck and where there are at least
two escape routes direct to the open deck at every accommodation level,
consideration may be given by the Administration to reducing the "A-0"
requirements of paragraph 1 to "B-0".
3 All stairways shall be of steel frame construction except where the
Administration sanctions the use of other equivalent material.
Regulation 47 Doors in fire resisting divisions
1 The fire resistance of doors shall, as far as practicable, be
equivalent to that of the division in which they are fitted. Doors and
door frames in "A" class divisions shall be constructed of steel. Doors in
"B" class divisions shall be non-combustible. Doors fitted in boundary
bulkheads of machinery spaces of category A shall be reasonably gastight
and self-closing. In ships constructed according to method IC, an
Administration may permit the use of combustible materials in doors
separating cabins from individual interior sanitary accommodation such as
showers.
2 Doors required to be self-closing shall not be fitted with hold-back
hooks. However, hold-back arrangements fitted with remote release devices
of the fail-safe type may be utilized.
3 In corridor bulkheads ventilation openings may be permitted only in
and under the doors of cabins and public spaces. The openings shall be
provided only in the lower half of a door. Where such opening is in or
under a door the total net area of any such opening or openings shall not

accommodation and service spaces and control stations, ceilings, linings,
draught stops and their associated grounds shall be of non-combustible
materials.
3 Methods IC, IIC and IIIC
3.1 Except in cargo spaces or refrigerated compartments of service
spaces, insulating materials shall be non-combustible. Vapour barriers and
adhesives used in conjunction with insulation, as well as the insulation
of pipe fittings, for cold service systems, need not be of non-combustible
materials, but they shall be kept to the minimum quantity practicable and
their exposed surfaces shall have qualities of resistance to the
propagation of flame to the satisfaction of the Administration.
3.2 Where non-combustible bulkheads, linings and ceilings are fitted
in accommodation and service spaces they may have a combustible veneer not
exceeding 2.0 mm in thickness within any such space except corridors,
stairway enclosures and control stations, where the veneer shall not
exceed 1.5 mm in thickness.
3.3 Air spaces enclosed behind ceilings, panellings, or linings, shall
be divided by close-fitting draught stops spaced not more than 14 m apart.
In the vertical direction, such air spaces, including those behind linings
of stairways, trunks, etc., shall be closed at each deck.
Regulation 51 Arrangements for gaseous fuel for domestic purposes
Where gaseous fuel is used for domestic purposes the arrangements,
storage, distribution and utilization of the fuel shall be such that,
having regard to the hazards of fire and explosion which the use of such
fuel may entail, the safety of the ship and the persons on board is
preserved.
Regulation 52 Fixed fire detection and fire alarm systems, Automa-tic sprinkler, fire detection and fire alarm systems
1 In ships in which method IC is adopted, a smoke detection system in
accordance with the relevant provisions of Regulation 13 shall be so
installed and arranged as to protect all corridors, stairways and escape
routes within accommodation spaces.
2 In ships in which method IIC is adopted, an automatic sprinkler,
fire detection and fire alarm system of an approved type and complying
with the relevant provisions of Regulation 12 shall be so installed and
arranged as to protect accommodation spaces, galleys and other service
spaces, except spaces which afford no substantial fire risk such as void
spaces, sanitary spaces, etc. In addition, a smoke detection system in
accordance with the relevant provisions of Regulation 13 shall be so
arranged and installed as to protect corridors, stairways and escape
routes within accommodation spaces.
3 In ships in which method IIIC is adopted, a fixed fire detection and
fire alarm system of an approved type and complying with the relevant
provisions of Regulation 13 shall be so installed and arranged as to
detect the presence of fire in all accommodation spaces and service
spaces, except spaces which afford no substantial fire risk such as void
spaces, sanitary spaces, etc.
4 Notwithstanding the provisions of the above, the Administration need
not require the installation of detectors required in accordance with the
provisions of Regulation 13.2.2 until 1 September 1985.
Regulation 53 Fire protection arrangements in cargo spaces
1 General
1.1 Except for cargo spaces covered in paragraphs 2 and 3, cargo
spaces of ships of 2,000 tons gross tonnage and upwards shall be protected
by a fixed gas fire-extinguishing system complying with the provisions of
Regulation 5 or by a fire-extinguishing system which gives equivalent
protection.
1.2 The Administration may exempt from the requirements of paragraph
1.1 cargo spaces of any ship if constructed and solely intended for
carrying ore, coal, grain, unseasoned timber and non-combustible cargoes
or cargoes which, in the opinion of the Administration, constitute a low
fire risk. Such exemptions may be granted only if the ship is fitted with
steel hatch covers and effective means of closing all ventilators and
other openings leading to the cargo spaces.
1.3 Notwithstanding the provisions of paragraph 1.1, any ship engaged
in the carriage of dangerous goods shall be provided in any cargo spaces
with a fixed gas fire-extinguishing system complying with the provisions
of Regulation 5 or by a fire-extinguishing system which in the opinion of
the Administration give equivalent protection for the cargoes carried.
2 Ro/ro cargo spaces
2.1 Fire detection
There shall be provided an approved automatic fire detection and fire
alarm system. The design and arrangements of this system shall be
considered in conjunction with the ventilation requirements referred to in
2.3.
2.2 Fire-extinguishing arrangements
2.2.1 Ro/ro cargo spaces capable of being sealed shall be fitted with
a fixed gas fire-extinguishing system which shall comply with the
provisions of Regulation 5, except that:
.1 if a carbon dioxide system is fitted, the quantity of gas
available shall be at least sufficient to give a minimum volume of free
gas equal to 45 per cent of the gross volume of the largest such cargo
space which is capable of being sealed, and the arrangements shall be such
as to ensure that at least two thirds of the gas required for the relevant
space shall be introduced during 10 minutes;
.2 a halogenated hydrocarbon system may be used only for spaces
designated only for vehicles which are not carrying any cargo;
.3 any other fixed gas fire-extinguishing system or fixed high
expansion foam fire-extinguishing system may be fitted provided the
Administration is satisfied that an equivalent protection is achieved;
.4 as an alternative, a system meeting the requirements of
Regulation 37.1.3 may be fitted. However, the drainage and pumping
arrangement shall be such as to prevent the build-up of free surfaces. If
this is not possible the adverse effect upon stability of the added weight
and free surface of water shall be taken into account to the extent deemed
necessary by the Administration in its approval of the stability
information. * Such information shall be included in the stability
information supplied to the master as required by Regulation II-1/22.
2.2.2 Ro/ro cargo spaces not capable of being sealed shall be fitted
with a system meeting the requirements of Regulation 37.1.3. However, the
drainage and pumping arrangements shall be such as to prevent the build-up
of free surfaces. If this is not possible the adverse effect upon
stability of the added weight and free surface of water shall be taken
into account to the extent deemed necessary by the Administration in its
approval of the stability information *. Such information shall be
included in the stability information supplied to the master as required
