AMENDMENTS TO THE INTERNATIONAL CONVENTION FOR THE SAFETY OF LIFEAT SEA, 1974
AMENDMENTS TO THE INTERNATIONAL CONVENTION FOR THE SAFETY OF LIFEAT SEA, 1974
[Adopted on 20 November 1981 by Resolution MSC .1 (XLV)] 5.1 An independent power pump shall be provided solely for the purpose
of continuing automatically the discharge of water from the sprinklers.
The pump shall be brought into action automatically by the pressure drop
in the system before the standing fresh water charge in the pressure tank
is completely exhausted.
5.2 The pump and the piping system shall be capable of maintaining the
necessary pressure at the level of the highest sprinkler to ensure a
continuous output of water sufficient for the
2 simultaneous coverage of
a minimum area of 280 m at the application rate specified in paragraph 3.
5.3 The pump shall have fitted on the delivery side a test valve with
a short open-ended discharge pipe. The effective area through the valve
and pipe shall be adequate to permit the release of the required pump
output while maintaining the pressure in the system specified in paragraph
4.1.
5.4 The sea inlet to the pump shall wherever possible be in the space
containing the pump and shall be so arranged that when the ship is afloat
it will not be necessary to shut off the supply of sea-water to the pump
for any purpose other than the inspection or repair of the pump.
6 The sprinkler pump and tank shall be situated in a position
reasonably remote from any machinery space of category A and shall not be
situated in any space required to be protected by the sprinkler system.
7.1 In passenger ships there shall be not less than two sources of
power supply for the seawater pump and automatic alarm and detection
system. Where the sources of power for the pump are electrical, these
shall be a main generator and an emergency source of power. One supply for
the pump shall be taken from the main switchboard, and one from the
emergency switchboard by separate feeders reserved solely for that
purpose. The feeders shall be so arranged as to avoid galleys, machinery
spaces and other enclosed space of high risk except in so far as it is
necessary to reach the appropriate switchboards, and shall be run to an
automatic change-over switch situated near the sprinkler pump. This switch
shall permit the supply of power from the main switchboard so long as a
supply is available therefrom, and be so designed that upon failure of
that supply it will automatically change over to the supply from the
emergency switchboard. The switches on the main switchboard and the
emergency switchboard shall be clearly labelled and normally kept closed.
No other switch shall be permitted in the feeders concerned. One of the
sources of power supply for the alarm and detection system shall be an
emergency source. Where one of the sources of power for the pump is an
internal combustion engine it shall, in addition to complying with the
provisions of paragraph 6, be so situated that a fire in any protected
space will not affect the air supply to the machinery.
7.2 In cargo ships there shall not be less than two sources of power
supply for the sea-water pump and automatic alarm and detection system. If
the pump is electrically driven it shall be connected to the main source
of electrical power, which shall be capable of being supplied by at least
two generators. The feeders shall be so arranged as to avoid galleys,
machinery spaces and other enclosed spaces of high fire risk except in so
far as it is necessary to reach the appropriate switchboards. One of the
sources of power supply for the alarm and detection system shall be an
emergency source. Where one of the sources of power for the pump is an
internal combustion engine it shall, in addition to complying with the
provisions of paragraph 6, be so situated that a fire in any protected
space will not affect the air supply to the machinery.
8 The sprinkler system shall have a connexion from the ship's fire
main by way of a lockable screw-down non-return valve at the connexion
which will prevent a backflow from the sprinkler system to the fire main.
9.1 A test valve shall be provided for testing the automatic alarm for
each section of sprinklers by a discharge of water equivalent to the
operation of one sprinkler. The test valve for each section shall be
situated near the stop valve for that section.
9.2 Means shall be provided for testing the automatic operation of the
pump on reduction of pressure in the system.
9.3 Switches shall be provided at one of the indicating positions
referred to in paragraph 1. 2 which will enable the alarm and the
indicators for each section of sprinklers to be tested.
10 Spare sprinkler heads shall be provided for each section of
sprinklers to the satisfaction of the Administration.
Regulation 13 Fixed fire detection and fire alarm systems
1 General requirements
1.1 Any required fixed fire detection and fire alarm system with
manually operated call points shall be capable of immediate operation at
all times.
1.2 Power supplies and electric circuits necessary for the operation
of the system shall be monitored for loss of power of fault conditions as
appropriate. Occurrence of a fault condition shall initiate a visual and
audible fault signal at the control panel which shall be distinct from a
fire signal.
1.3 There shall be not less than two sources of power supply for the
electrical equipment used in the operation of the fire detection and fire
alarm system, one of which shall be an emergency source. The supply shall
be provided by separate feeders reserved solely for that purpose. Such
feeders shall run to an automatic change-over switch situated in or
adjacent to the control panel for the fire detection system.
1.4 Detectors and manually operated call points shall be grouped into
sections. The activation of any detector or manually operated call point
shall initiate a visual and audible fire signal at the control panel and
indicating units. If the signals have not received attention within two
minutes an audible alarm shall be automatically sounded throughout the
crew accommodation and service spaces, control stations and machinery
spaces of category A. This alarm sounder system need not be an integral
part of the detection system.
1.5 The control panel shall be located on the navigating bridge or in
the main fire control station.
1.6 Indicating units shall denote the section in which a detector or
manually operated call point has operated. At least one unit shall be so
located that it is easily accessible to responsible members of the crew at
all times, when at sea or in port except when the ship is out of service.
One indicating unit shall be located on the navigating bridge if the
control panel is located in the main fire control station.
7 Clear information shall be displayed on or adjacent to each
indicating unit about the spaces covered and the location of the sections.
1.8 No section covering more than one deck within accommodation,
service and control stations shall normally be permitted except a section
which covers an enclosed stairway. In order to avoid delay in identifying
the source of fire, the number of enclosed spaces included in each section
shall be limited as determined by the Administration. In no case shall
more than fifty enclosed spaces be permitted in any section.
1.9 In passenger ships a section of detectors shall not serve spaces
on both sides of the ship nor on more than one deck and neither shall it
be situated in more than one main vertical zone except that the
Administration, if it is satisfied that the protection of the ship against
fire will not thereby be reduced, may permit such a section of detectors
to serve both sides of the ship and more than one deck.
1.10 A section of fire detectors which covers a control station, a
service space or an accommodation space shall not include a machinery
space of category A.
1.11 Detectors shall be operated by heat, smoke or other products of
combustion, flame, or any combination of these factors. Detectors
operated by other factors indicative of incipient fires may be considered
by the Administration provided that they are no less sensitive than such
detectors. Flame detectors shall only be used in addition to smoke or heat
detectors.
1.12 Suitable instructions and components spares for testing and
maintenance shall be provided.
1.13 The function of the detection system shall be periodically tested
to the satisfaction of the Administration by means of equipment producing
hot air at the appropriate temperature, or smoke or aerosol particles
having the appropriate range of density or particle size, or other
phenomena associated with incipient fires to which the detector is
designed to respond. All detectors shall be of a type such that they can
be tested for correct operation and restored to normal surveillance
without the renewal of any component.
1.14 The fire detection system shall not be used for any other
purpose, except that closing of fire doors and similar functions may be
permitted at the control panel.
2 Installation requirements
2.1 Manual call points shall be installed throughout the accommodation
spaces, service spaces and control stations. One manual call point shall
be located at each exit. Manual call points shall be readily accessible in
the corridors of each deck such that no part of the corridor is more than
20 m from a manual call point.
2.2 Smoke detectors shall be installed in all stairways, corridors and
escape routes within accommodation spaces. Consideration shall be given to
the installation of special purpose smoke detectors within ventilation
ducting.
2.3 Where a fixed fire detection and fire alarm system is required for
the protection of spaces other than those specified in paragraph 2.2, at
least one detector complying with paragraph 1.11 shall be installed in
each such space.
2.4 Detectors shall be located for optimum performance. Positions near
beams and ventilation ducts or other positions where patterns of air flow
could adversely affect performance and positions where impact or physical
damage is likely shall be avoided. In general, detectors which are located
on the overhead shall be a minimum distance of 0.5 m away from bulkheads.
2.5 The maximum spacing of detectors shall be in accordance with the
table below:
|-----------------------
| Type of | Maximum floor area | Maximum distance apart | Maximum distance away |
| detector | per detector | between centres | from bulkheads |

| 2 | |
| Heat | 37 m | 9 m | 4.5 m |
|----|------|--------|-------|
| 2 | |
| Smoke | 74 m | 11 m | 5.5 m |
|-----------------------
The Administration may require or permit other spacings based upon
test data which demonstrate the characteristics of the detectors.
2.6 Electrical wiring which forms part of the system shall be so
arranged as to avoid galleys, machinery spaces of category A, and other
enclosed spaces of high fire risk except where it is necessary to provide
for fire detection or fire alarm in such spaces or to connect to the
appropriate power supply.
3 Design requirements
3.1 The system and equipment shall be suitably designed to withstand
supply voltage variation and transients, ambient temperature changes,
vibration, humidity, shock, impact and corrosion normally encountered in
ships.
3.2 Smoke detectors required by paragraph 2.2 shall be certified to
operate before the smoke density exceeds 12.5 per cent obscuration per
metre, but not until the smoke density exceeds 2 per cent obscuration per
metre. Smoke detectors to be installed in other spaces shall operate
within sensitivity limits to the satisfaction of the Administration having
regard to the avoidance of detector insensitivity or oversensitivity.
3.3 Heat detectors shall be certified to operate before the
temperature exceeds 78¡æ but not until the temperature exceeds 54 ¡æ, when
the temperature is raised to those limits at a rate less than 1¡æ per
minute. At higher rates of temperature rise, the heat detector shall
operate within temperature limits to the satisfaction of the
Administration having regard to the avoidance of detector insensitivity or
oversensitivity.
3.4 At the discretion of the Administration, the permissible
temperature of operation of heat detectors may be increased to 30¡æ above
the maximum deckhead temperature in drying rooms and similar spaces of a
normal high ambient temperature.
Regulation 14 Fixed fire detection and fire alarm systems for pe-riodically unattended machinery spaces
1 A fixed fire detection and fire alarm system in accordance with the
relevant provisions of Regulation 13 shall be installed in periodically
unattended machinery spaces.
2 This fire detection system shall be so designed and the detectors so
positioned as to detect rapidly the onset of fire in any part of those
spaces an d under any normal conditions of operation of the machinery and
variations of ventilation as required by the possible range of ambient
temperature. Except in spaces of restricted height and where their use is
specially appropriate, detection systems using only thermal detector shall
not be permitted. The detection system shall initiate audible and visual
alarms distinct in both respects from the alarms of any other system not
indicating fire, in sufficient places to ensure that the alarms are heard
and observed on the navigating bridge and by a responsible engineer
officer. When the navigating bridge is unmanned the alarm shall sound in a
place where a responsible member of the crew is on duty.
3 After installation the system shall be tested under varying
conditions of engine operation and ventilation.
Regulation 15 Arrangements for oil fuel, lubricating oil and otherflammable oils
1 Limitations in the use of oil as fuel
The following limitations shall apply to the use of oil as fuel:
.1 Except as otherwise permitted by this paragraph, no oil fuel
with a flashpoint of less than 60 ¡æ shall be used.
.2 In emergency generators oil fuel with a flashpoint of not less
than 43 ¡æ may be used.
.3 Subject to such additional precautions as it may consider
necessary and on condition that the ambient temperature of the space in
which such oil fuel is stored or used shall not be allowed to rise to
within 10¡æ below the flashpoint of the oil fuel, the Administration may
permit the general use of oil fuel having a flashpoint of less than 60¡æ
but not less than 43¡æ.
.4 In cargo ships the use of fuel having a lower flashpoint than
otherwise specified in this paragraph, for example crude oil, may be
permitted provided that such fuel is not stored in any machinery space and
subject to the approval by the Administration of the complete
installation.
The flashpoint of oils shall be determined by an approved closed cup
method.
2 Oil fuel arrangements
In a ship in which oil fuel is used, the arrangements for the storage,
distribution and utilization of the oil fuel shall be such as to ensure
the safety of the ship and persons on board and shall at least comply with
the following provisions:
.1 As far as practicable, parts of the oil fuel system containing
heated oil under pressureexceeding 0.18 N/square mm shall not be placed
in a concealed position such that defects and leakage cannot readily be
observed .The machinery spaces in way of such parts of the oil fuel system
shall be adequately illuminated.
.2 The ventilation of machinery spaces shall be sufficient under
all normal conditions to prevent accumulation of oil vapour.
.3 As far as practicable, oil fuel tanks shall be part of the
ship's structure and shall be located outside machinery spaces of category
A. Where oil fuel tanks, other than double bottom tanks, are necessarily
located adjacent to or within machinery spaces of category A, at least one
of their vertical sides shall be contiguous to the machinery space
boundaries, and shall preferably have a common boundary with the double
bottom tanks, and the area of the tank boundary common with the machinery
spaces shall be kept to a minimum. Where such tanks are situated within
the boundaries of machinery spaces of category A they shall not contain
oil fuel having a flashpoint of less than 60¡æ. In general the use of free
standing oil fuel tanks shall be avoided. When such tanks are employed
their use shall be prohibited in category A machinery spaces on passenger
ships. Where permitted, they shall be placed in an oil-tight spill tray of
ample size having a suitable drain pipe leading to a suitably sized spill
oil tank.
.4 No oil fuel tank shall be situated where spillage or leakage
therefrom can constitute a hazard by falling on heated surfaces.
Precautions shall be taken to prevent any oil that may escape under
pressure from any pump, filter or heater from coming into contact with
heated surfaces.
.5 Every oil fuel pipe, which, if damaged, would allow oil to
escape from a storage, settling or daily service tank situated above the
double bottom shall be fitted with a cock or valve directly on the tank
capable of being closed from a safe position outside the space concerned
in the event of a fire occurring in the space in which such tanks are
situated. In the special case of deep tanks situated in any shaft or pipe
tunnel or similar space, valves on the tank shall be fitted but control in
the event of fire may be effected by means of an additional valve on the
pipe or pipes outside the tunnel or similar space. If such additional
valve is fitted in the machinery space it shall be operated from a
position outside this space.
.6 Safe and efficient means of ascertaining the amount of oil fuel
contained in any oil fuel tank shall be provided. Sounding pipes shall not
terminate in any space where the risk of ignition of spillage from the
sounding pipe might arise. In particular, they shall not terminate in
passenger or crew spaces. Other means of ascertaining the amount of oil
fuel contained in any oil fuel tank may be permitted:
6.1 in passenger ships, if such means do not require penetration
below the top of the tank, and providing their failure or over-filling of
the tanks will not permit release of fuel;
6.2 in cargo ships, providing the failure of such means or
over-filling of the tanks will not permit release of fuel. The use of
cylindrical gauge glasses is prohibited. The Administration may permit the
use of oil level gauges with flat glasses and self-closing valves between
the gauges and oil tanks.
Such other means shall be acceptable to the Administration and
shall be maintained in the proper condition to ensure their continued
accurate functioning in service.
.7 Provision shall be made to prevent overpressure in any oil tank
or in any part of the oil fuel system, including the filling pipes. Any
relief valves and air or overflow pipes shall discharge to a position
which, in the opinion of the Administration, is safe.
.8 Oil fuel pipes and their valves and fittings shall be of steel
or other approved material, except that restricted use of flexible pipes
shall be permissible in positions where the Administration is satisfied
that they are necessary. Such flexible pipes and end attachments shall be
of approved fire-resisting materials of adequate strength and shall be
constructed to the satisfaction of the Administration.
3 Lubricating oil arrangements
The arrangements for the storage, distribution and utlization of oil
used in pressure lubrication systems shall be such as to ensure the safety
of the ship and persons on board, and such arrangements in machinery
spaces of category A and whenever practicable in other machinery spaces
shall at least comply with the provisions of paragraphs 2.1, 2.4, 2.5,
2.6, 2.7 and 2.8, except that this does not preclude the use of sight
flow glasses in lubricating systems provided that they are shown by test
to have a suitable degree of fire resistance.
4 Arrangements for other flammable oils
The arrangements for the storage, distribution and utilization of
other flammable oils employed under pressure in power transmission
systems, control and activating systems and heating systems shall be such
as to ensure the safety of the ship and persons on board. In locations
where means of ignition are present, such arrangements shall at least
comply with the provisions of paragraphs 2.4 and 2.6, and with the
provisions of paragraphs 2.7 and 2. 8 in respect of strength and
construction.
5 Periodically unattended machinery spaces
In addition to the requirements of paragraphs 1 to 4, the oil fuel and
lubricating oil systems shall comply with the following:
.1 Where necessary, oil fuel and lubricating oil pipelines shall
be screened or otherwise suitably protected to avoid as far as practicable
oil spray or oil leakages on to hot surfaces or into machinery air
intakes. The number of joints in such piping systems shall be kept to a
minimum and, where practicable, leakages from high pressure oil fuel pipes
shall be collected and arrangements provided for an alarm to be given.
.2 Where daily service oil fuel tanks are filled automatically, or
by remote control, means shall be provided to prevent overflow spillages.
Other equipment which treats flammable liquids automatically, e.g. oil
fuel purifiers, which, whenever practicable, shall be installed in a
special space reserved for purifiers and their heaters, shall have
arrangements to prevent overflow spillages.
.3 Where daily service oil fuel tanks or settling tanks are fitted
with heating arrangements, a high temperature alarm shall be provided if
the flashpoint of the oil fuel can be exceeded.

PART D FIRE SAFETY MEASURES FOR PASSENGER SHIPS
Regulation 23 Structure
1 The hull, superstructure, structural bulkheads, decks and deckhouses
shall be constructed of steel or other equivalent material. For the
purpose of applying the definition of steel or other equivalent material
as given in Regulation 3.7 the "applicable fore exposure" shall be
according to the integrity and insulation standards given in the tables of
Regulation 26 and 27. For example where divisions such as decks or sides
and ends of deckhouses are permitted to have "B-0" fire integrity, the
"applicable fire exposure" shall be half an hour.
2 However, in cases where any part of the structure is of aluminium
alloy, the following shall apply:
.1 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 ¡æabove the ambient
temperature at any time during the applicable fire exposure to the
standard fire test.
.2 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:
.2.1 that for such members supporting lifeboat and liferaft areas
and "A" class divisions, the temperature rise limitation specified in
paragraph 2.1 shall apply at the end of one hour; and
.2.2 that for such members required to support "B" class
divisions, the temperature rise limitation specified in paragraph 2.1
shall apply at the end of half an hour.
3 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.
Regulation 24 Main vertical zones and horizontal zones
1.1 For ships carrying more than 36 passengers, the hull,
superstructure and deckhouses shall be subdivided into main vertical zones
by "A" class divisions. Steps and recesses shall be kept to a minimum, but
where they are necessary they shall also be "A" class divisions. These
divisions shall have insulation values in accordance with tables in
Regulation 26.
1.2 For ships carrying not more than 36 passengers, the hull,
superstructure and deckhouses in way of accommodation and service spaces
shall be subdivided into main vertical zones by "A" class division. These
divisions shall have insulation values in accordance with tables in
Regulation 27.
2 As far as practicable, the bulkheads forming the boundaries of the
main vertical zones above the bulkhead deck shall be in line with
watertight subdivision bulkheads situated immediately below the bulkhead
deck.
3 Such bulkheads shall extend from deck to deck and to the shell or
other boundaries.
4 Where a main vertical zone is subdivided by horizontal "A" class
divisions into horizontal zones for the purpose of providing an
appropriate barrier between sprinklered and non-sprinklered zones of the
ship, the divisions shall extend between adjacent main vertical zone
bulkheads and to the shell or exterior boundaries of the ship and shall be
insulated in accordance with the fire insulation and integrity values
given in table 26.3 or in table 27.2.
5.1 On ships designed for special purposes, such as automobile or
railroad car ferries, where the provision of main vertical zone bulkheads
would defeat the purpose for which the ship is intended, equivalent means
for controlling and limiting a fire shall be substituted and specifically
approved by the Administration.
5.2 However, in a ship with special category spaces, any such space
shall comply with the applicable provisions of Regulation 37 and in so far
as such compliance would be inconsistent with compliance with other
requirements of this Part, the requirements of Regulation 37 shall
prevail.
Regulation 25 Bulkheads within a main vertical zone
1.1 For ships carrying more than 36 passengers all bulkheads which are
not required to be "A" class divisions shall be at least "B" class or "C"
class divisions as prescribed in the tables in Regulation 26.
1.2 For ships carrying not more than 36 passengers all bulkheads
within accommodation and service spaces which are not required to be "A"
class divisions shall be at least "B" class or "C" class divisions as
prescribed in the tables in Regulation 27.
1.3 All such divisions may be faced with combustible materials in
accordance with the provisions of Regulation 34.
2 All corridor bulkheads where not required to be "A" class shall be
"B" class divisions which shall extend from deck to deck except:
.1 when continuous "B" class ceilings or linings are fitted on
both sides of the bulkhead, the portion of the bulkhead behind the
continuous ceiling or lining shall be of material which, in thickness and
composition, is acceptable in the construction of "B" class divisions but
which shall be required to meet "B" class integrity standards only in so
far as is reasonable and practicable in the opinion of the Administration;
.2 in the case of a ship protected by an automatic sprinkler
system complying with the provisions of Regulation 12 the corridor
bulkheads of "B" class materials may terminate at a ceiling in the
corridor provided such a ceiling is of material which, in thickness and
composition, is acceptable in the construction of "B" class divisions.
Notwithstanding the requirements of Regulations 26 and 27 such bulkheads
and ceilings shall be required to meet "B" class integrity standards only
in so far as is reasonable and practicable in the opinion of the
Administration. All doors and frames in such bulkheads shall be of
non-combustible materials and shall be so constructed and erected as to
provide substantial fire resistance to the satisfaction of the
Administration.
3 All bulkheads required to be "B" class divisions, except corridor
bulkheads, 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.
Regulation 26 Fire integrity of bulkheads and decks in ships car-rying 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 all bulkheads and decks shall be as prescribed
in tables 26.1 to 26.4. Where, due to any particular structural
arrangements in the ship, difficulty is experienced in determining from
the tables the minimum fire integrity value of any divisions, such values
shall be determined to the satisfaction of the Administration.
2 The following requirements shall govern application of the tables:
.1 Table 26.1 shall apply to bulkheads bounding main vertical
zones or horizontal zones.
Table 26.2 shall apply to bulkheads not bounding either main
vertical zones or horizontal zones.
Table 26.3 shall apply to decks forming steps in main vertical
zones or bounding horizontal zones.
Table 26.4 shall apply to decks not forming steps in main
vertical zones nor bounding horizontal zones.
.2 for the purpose of determining the appropriate fire integrity
standards to be applied to boundaries between adjacent spaces, such spaces
are classified according to their fire risk as shown in categories (1) to
(14) below. Where the contents and use of a space are such that there is a
doubt as to its classification for the purpose of this Regulation, it
shall be treated as a space within the relevant category having the most

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 ¡ã 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

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:
*
