CHAPTER II-2
CONSTRUCTION - FIRE PROTECTION,
FIRE DETECTION AND FIRE EXTINCTION
1.1 Unless expressly provided otherwise, this chapter shall apply
to ships the keels of which are laid or which are at a similar stage of
construction on or after 1 July 1986.
1.2 For the purpose of this chapter the term "a similar stage
of construction" means the stage at which:
.1 construction identifiable
with a specific ship begins; and
.2 assembly of that ship has
commenced comprising at least 50 tonnes or 1 % of the estimated mass of all
structural material, whichever is less.
1.3 For the purpose of this chapter:
.1 the expression
"ships constricted" means "ships the keels of which are laid or
which are at a similar stage of construction";
.2 the expression "all
ships" means "ships constructed before, on or after 1 July
1986";
.3 a cargo ship, whenever
built, which is converted to a passenger ship shall be treated as a passenger
ship constricted on the date on which such a conversion commences.
2 Unless expressly provided otherwise, for ships constructed
before 1 July 1986 the Administration shall ensure that the requirements which
are applicable under chapter II-2 of the International Convention for the
Safety of Life at Sea, 1974, as amended by resolution MSC.1 (XLV) are complied
with.
3.1 All ships which undergo repairs, alterations, modifications
and outfitting related thereto shall continue to comply with at least the
requirements previously applicable to these ships. Such ships, if constructed
before 1 July 1986 shall, as a rule, comply with the requirements for ships
constructed on or after that date to at least the same extent as they did
before undergoing such repairs, alterations, modifications or outfitting.
Repairs, alterations and modifications of a major character and outfitting
related thereto shall meet the requirements for ships constructed on or after 1
July 1986 in so far as the Administration deems reasonable and practicable.
3.2 Notwithstanding the provisions of paragraph 3.1, passenger
ships carrying more than 36 passengers when undergoing repairs, alterations,
modifications and outfitting related thereto shall comply with the following:
.1 all materials introduced
to these ships shall comply with the requirements with regard to material
applicable to ships constructed on or after 1 October 1994; and
.2 all repairs, alterations,
modifications and outfittings related thereto involving the replacement of
material of 50 tonnes or above, other than those required by regulation
II-2/41-1, shall comply with the requirements applicable to such ships
constructed on or after 1 October 1994.
4.1 The Administration of a State may, if it considers that the
sheltered nature and conditions of the voyage are such as to render the
application of any specific requirements of this chapter unreasonable or
unnecessary, exempt from those requirements individual ships or classes of
ships entitled to fly the flag of the State which, in the course of their
voyage, do not proceed more than 20 miles from the nearest land.
4.2 In the case of passenger ships which are employed in special
trades for the carriage of large numbers of special trade passengers, such as
the pilgrim trade, the Administration of the State whose flag such ships are
entitled to fly, if satisfied that it is impracticable to enforce compliance
with the requirements of this chapter, may exempt such ships from those
requirements, provided that they comply fully with provision of:
.1 the Rules annexed to the
Special Trade Passenger Ships Agreement, 1971; and
.2 the Rules annexed to
"the Protocol on Space Requirements for Special Trade Passenger Ships,
1973.
Regulation 2.
Basic principles
1 The purpose of this chapter is to require the fullest practicable
degree of fire protection, fire detection and fire extinction in ships.
2 The following basic principles underlie the regulations in this
chapter and are embodied in the regulations as appropriate, having regard to
the type of ships and the potential fire hazard involved:
.1 division of ship into
main vertical zones by thermal and structural boundaries;
.2 separation of
accommodation spaces from the remainder of the ship by thermal and structural
boundaries;
.3 restricted use of
combustible materials;
.4 detection of any fire in
the zone of origin;
.5 containment and
extinction of any fire in the space of origin;
.6 protection of means of
escape or access for fire fighting;
.7 ready availability of
fire-extinguishing appliances;
.8 minimization of
possibility of ignition of flammable cargo vapour.
Regulation 3.
Definitions For the purpose of this chapter, unless expressly provided
otherwise:
1 "Non-combustible material" is a material which neither
burns nor gives off flammable vapours in sufficient quantity for self-ignition
when heated to approximately 750°C, this being determined to the satisfaction
of the Administration by an established test procedure*. Any other material is
a combustible material.
2 "A standard fire test" is one in which specimens of
the relevant bulkheads or decks are exposed in a test furnace to temperatures
corresponding approximately to the standard time-temperature curve. The
specimen shall have an exposed surface of not less than 4.65 m2 and
height (or length of deck) of 2.44 m, resembling as closely as possible the
intended construction and including where appropriate at least one joint. The
standard time-temperature curve is defined by a smooth curve drawn through the
following temperature points measured above the initial furnace temperature:
at the end of the first 5 minutes 556"C
" 10 minutes 659°C
" 15 minutes 718°C
" 30 minutes 821° Ñ
" 60 minutes 925°C
3 ""A" class divisions" are those divisions
formed by bulkheads and decks which comply with the following:
.1 they shall be constructed
of steel or other equivalent material;
.2 they shall be suitably
stiffened;
.3 they shall be so
constructed as to be capable of preventing the passage of smoke and flame to
the end of the one-hour standard fire test;
.4 they shall be insulated
with approved non-combustible materials such that the average temperature of
the unexposed side will not rise more than 139°C above the original
temperature, nor will the temperature, at any point, including any joint, rise
more than 180°C above the original temperature, within the time listed below;
class "A-60" 60 minutes
class "A-30" 30 minutes
class "A-15" 15 minutes
class "A-0" 0 minutes
.5 the Administration may
require a test of a prototype bulkhead or deck to ensure that it meets the
above requirements for integrity and temperature rise**.

require a test of a prototype division to ensure that it meets the above
requirements for integrity and temperature rise".
5 ""C" class divisions" are divisions
constructed of approved non-combustible materials. They need meet neither
requirements relative to the passage of smoke and flame nor limitations
relative to the temperature rise. Combustible veneers are permitted provided
they meet other requirements of this chapter.
6 "Continuous "B" class ceilings or linings"
are those "B" class ceilings or linings which terminate only at an
"A" or "B" class division.
7 "Steel or other equivalent material". Where the words
"steel or other equivalent material" occur, "equivalent
material" means any non-combustible material which, by itself or due to
insulation provided, has structural and integrity properties equivalent to
steel at the end of the applicable exposure to the standard fire test (e.g.
aluminium ally with appropriate insulation).
8 "Low flame spread** means that the surface thus described
will adequately restrict the spread of flame, this being determined to the
satisfaction of the Administration by an established test procedure.
