Textual Amendments
The insulation of aluminium alloy components of ‘ A ’ or ‘ B ’ class divisions, except structure which is non-load-bearing, shall be such that the temperature of the structural core does not rise more than 200 °C above the ambient temperature at any time during the applicable fire exposure to the standard fire test.
Special attention shall be given to the insulation of aluminium alloy components of columns, stanchions and other structural members required to support lifeboat and life-raft stowage, launching and embarkation areas, and ‘ A ’ and ‘ B ’ class divisions to ensure:
that for such members supporting lifeboat and life-raft areas and ‘ A ’ class divisions, the temperature rise limitation specified in paragraph .2.1 shall apply at the end of one hour; and
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.
Crowns and casings of category A machinery spaces shall be of steel construction adequately insulated and openings therein, if any, shall be suitably arranged and protected to prevent the spread of fire.
Steps and recesses shall be kept to a minimum but where they are necessary, they shall also be A-60 class divisions.
Where an open deck space, a sanitary or similar space or a tank including a fuel oil tank, void space or auxiliary machinery space having little or no fire risk, is on one side or where fuel oil tanks are on both sides of the division the standard may be reduced to A-0.
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 protection shall be obtained by dividing space in horizontal zones.
However, in a ship with special category spaces, any such space shall comply with the applicable provisions of Regulation II-2/B/14 and in so far as such compliance would be inconsistent with compliance with other requirements of this part, the requirements of Regulation II-2/B/14 shall prevail.
All such divisions may be faced with combustible materials in accordance with the provisions of Regulation 11.
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 case of a ship protected by an automatic sprinkler system complying with the provisions of Regulation II-2/A/8, the corridor bulkheads of ‘ B ’ class materials may terminate at a ceiling in the corridor provided such ceiling is of material which, in thickness and composition, is acceptable in the construction of ‘ B ’ class divisions.
Notwithstanding the requirements of Regulations II-2/B/4 and 5, such bulkheads and ceilings shall be required to meet ‘ B ’ class integrity standards only in so far as is reasonable and practicable. 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.
Table 4.1 shall apply to bulkheads not bounding either main vertical zones or bounding horizontal zones.
Table 4.2 shall apply to decks not forming steps in main vertical zones nor bounding horizontal zones.
For 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). 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 stringent boundary requirements. 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.

Notes to be applied to tables 5.1, 5.1(a), 5.2 and 5.2(a), as appropriate:] U.K.
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 one of the means of escape may be dispensed with, due regard being paid to the nature and location of spaces and to the number of persons who might be normally employed there.
In such a case the sole means of escape shall provide safe escape.
For ships which are constructed on or after 1 January 2003 , the abovementioned dispensation may only be given for crew spaces that are entered only occasionally, in which case the required escape route shall be independent of watertight doors.
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.
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.
In existing class B ships, a corridor, or part of a corridor from which there is only one route of escape shall not exceed:
5 metres in length for ships constructed on or after 1 October 1994 ,
13 metres in length for ships constructed before 1 October 1994 , carrying more than 36 passengers, and
7 metres in length for ships constructed before 1 October 1994 , carrying not more than 36 passengers.
In new class A, B, C and D ships of 24 metres in length and above, a corridor, lobby or part of a corridor from which there is only one route of escape shall be prohibited.
Dead-end corridors used in service areas which are necessary for the practical utility of the ship, such as fuel oil stations and athwartship supply corridors, shall be permitted, provided such dead-end corridors are separated from crew accommodation areas and inaccessible from passenger accommodation areas. A part of a corridor that has a depth not exceeding its width is considered a recess or local extension and is permitted.
In the latter case, direct access to the embarkation deck by way of external open stairways and passageways shall be provided and shall have emergency lighting in accordance with Regulation III/5.3 and slip-free surfaces underfoot. Boundaries facing external open stairways and passageways forming part of an escape route shall be so protected that a fire in any enclosed space behind such boundaries would not impede escape to the embarkation stations.
The widths, number and continuity of escapes shall be as follows:
Stairways shall not be less than 900 mm in clear width, if reasonable and practicable to the satisfaction of the Member State, but shall in no case be less than 600 mm. Stairways shall be fitted with handrails on each side. The minimum clear width of stairways shall be increased by 10 mm for every one person provided for in excess of 90 persons. The maximum clear width between handrails where stairways are wider than 900 mm shall be 1 800 mm. The total number of persons to be evacuated by such stairways shall be assumed to be two thirds of the crew and the total number of passengers in the areas served by such stairways. The width of the stairways shall at least conform to the standard as given in IMO Resolution A.757(18).
All stairways sized for more than 90 persons shall be aligned before and after.
Doorways and corridors and intermediate landings included in means of escape shall be sized in the same manner as stairways.
Stairways shall not exceed 3,5 metres in vertical rise without the provision of a landing and shall not have an angle of inclination greater than 45°.
Landings at each deck level shall not be less than 2 m 2 in area and shall increase by 1 m 2 for every 10 persons provided for in excess of 20 persons but need not exceed 16 m 2 , except for those landings servicing public spaces having direct access onto the stairway enclosure.
In the latter case direct access to the embarkation deck by way of external open stairways and passageways shall be provided and shall have emergency lighting in accordance with Regulation III/5.3 and slip-free surfaces underfoot. Boundaries facing external open stairways and passageways forming part of an escape route and boundaries in such a position that their failure during a fire would impede escape to the embarkation deck shall have fire integrity, including insulation values, in accordance with tables 4.1 to 5.2, as appropriate.
The widths, number and continuity of escapes shall be in accordance with the requirements of the Fire Safety Systems Code.
However, for new class B, C and D ships constructed on or after 1 January 2003 the Administration of the Flag State shall ensure that such lighting or photoluminescent equipment has been evaluated, tested and applied in accordance with the Fire Safety Systems Code.
Cabin and stateroom doors shall not require keys to unlock them from inside the room.
Neither shall there be any doors along any designated escape route which require keys to unlock them when moving in the direction of escape.
Escape doors from public spaces that are normally latched shall be fitted with a means of quick release. Such means shall consist of a door-latching mechanism incorporating a device that releases the latch upon the application of a force in the direction of escape flow. Quick release mechanisms shall be designed and installed to the satisfaction of the Administration of the flag State and in particular:
consist of bars or panels, the actuating portion of which extends across at least one half of the width of the door leaf, at least 760 mm and not more than 1 120 mm above the deck;
cause the door latch to release when a force not exceeding 67 N is applied; and
not be equipped with any locking device, set screw or other arrangement that prevents the release of the latch when pressure is applied to the releasing device.
In new class B, C and D ships constructed on or after 1 January 2003 , such spaces shall be provided with designated walkways to the means of escape with a breadth of at least 600 mm, and where practicable and reasonable those designated longitudinal walkways shall raise at least 150 mm above the deck surface. The parking arrangements for the vehicles shall maintain the walkways clear at all times.
Where the space is below the bulkhead deck the two means of escape shall consist of either:
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 there is access to the appropriate lifeboat and life-raft embarkation decks. In new ships, one of these ladders shall provide continuous fire shelter from the lower part of the space to a safe position outside the space. In new class B, C and D ships constructed on or after 1 January 2003 that ladder shall be located within a protected enclosure that satisfies Regulation II-2/B/4, category (2) or II-2/B/5, category (4), as appropriate, from the lower part of the space it serves to a safe position outside the space. Self-closing fire doors of the same fire integrity standards shall be fitted in the enclosure. The ladder shall be fixed in such a way that heat is not transferred into the enclosure through non-insulated fixing points. The protected enclosure shall have minimum internal dimensions of at least 800 mm × 800 mm, and shall have emergency lighting provisions; or
one steel ladder leading to a door 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.
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 a position from which access is provided to the appropriate lifeboat and life-raft embarkation decks. Where such means of escape require the use of ladders, these shall be of steel.
In a ship of 24 metres in length and above, the Administration of the flag State 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. In new class B, C and D ships constructed on or after 1 January 2003 , a second means of escape shall be provided in the steering gear space when the emergency steering position is located in that space unless there is a direct access to the open deck.
For new class B, C and D ro-ro passenger ships constructed on or after 1 July 1999 , escape routes shall be evaluated by an evacuation analysis early in the design process. The analysis shall be used to identify and eliminate, as far as practicable, congestion which may develop during abandonment, due to normal movement of passengers and crew along escape routes, including the possibility that crew may need to move along these routes in a direction opposite the movement of the passengers. In addition, the analysis shall be used to demonstrate that escape arrangements are sufficiently flexible to provide for the possibility that certain escape routes, assembly stations, embarkation stations or survival craft may not be available as a result of a casualty.
The doors shall be self-closing and be capable of closing with an angle of up to 3,5° opposing closure. The speed of closure shall, if necessary, be controlled so as to prevent undue danger to persons. In new ships the uniform rate of closure shall be no more than 0,2 m/s and no less than 0,1 m/s with the ship in the upright position.
Remote-controlled sliding or power-operated doors shall be equipped with an alarm that sounds at least 5 seconds but no more than 10 seconds before the door begins to move and continue sounding until the door is completely closed. Doors designed to re-open upon contacting an object in its path shall re-open sufficiently to allow a clear passage of at least 0,75 metres, but no more than one metre.
All doors, except fire doors which are normally kept closed, shall be capable of remote and automatic release from a continuously manned central control station, either simultaneously or in groups, and also individually from a position at both sides of the door. Indication must be provided at the fire control panel in the continuously manned central control station whether each of the remote-controlled doors is closed. The release mechanism shall be so designed that the door will automatically close in the event of disruption of the control system or central power supply. Release switches shall have an on-off function to prevent automatic resetting of the system. Holdback hooks not subject to central control station release are prohibited.
Local power accumulators for power-operated doors shall be provided in the immediate vicinity of the doors to enable the doors to be operated at least 10 times (fully opened and closed) using the local controls.
Double-leaf doors equipped with a latch necessary to their fire integrity shall have a latch that is automatically activated by the operation of the doors when released by the system.
Doors giving direct access to special category spaces which are power-operated and automatically closed need not be equipped with alarms and remote-release mechanisms required in .4.2 and .4.3.
Instead of .4 the following paragraph .4a shall apply
Fire doors in main vertical zone bulkheads, galley boundaries and stairway enclosures other than power-operated watertight doors and those which are normally locked, shall satisfy the following requirements:
the doors shall be self-closing and be capable of closing against an angle of inclination of up to 3,5° opposing closure;
the approximate time of closure for hinged fire doors shall be no more than 40 seconds and no less than 10 seconds from the beginning of their movement with the ship in upright position.
