The supply shall be provided by separate feeders reserved solely for that purpose. Such feeders shall run to an automatic changeover switch situated in or adjacent to the control panel for the fire detection system.

.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 2 minutes an audible alarm shall be automatically sounded throughout the crew accommodation and service spaces, control stations and machinery spaces. This alarm sounder system need not be an integral part of the detection system.

.5 The control panel shall be located on the navigating bridge or in the main fire control station.

.6 Indicating units shall, as a minimum, 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.

.8 Where the fire detection system does not include means of remotely identifying each detector individually, 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 of the flag State. In no case shall more than 50 enclosed spaces be permitted in any section. If the detection system is fitted with remotely and individually identifiable fire detectors, the sections may cover several decks and serve any number of enclosed spaces.

.9 If there is no fire detection system capable of remotely and individually identifying each detector, 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 of the flag State, 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. In ships fitted with individually identifiable fire detectors, a section may serve spaces on both sides of the ship and on several decks but may not be situated in more than one main vertical zone.

.10 A section of fire detectors which covers a control station, a service space or an accommodation space shall not include a machinery space.

.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 of the flag State provided that they are not less sensitive than such detectors. Flame detectors shall only be used in addition to smoke or heat detectors.

.12 Suitable instructions and component spares for testing and maintenance shall be provided.

.13 The functioning of the detection system shall be periodically tested to the satisfaction of the Administration of the flag State 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.

.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.

.15 Fire detection systems with a zone address identification capability shall be so arranged that:

• a loop cannot be damaged at more than one point by a fire,

• means are provided to ensure that any fault (e.g. power break, short circuit, earth) occurring in the loop will not render the whole loop ineffective,

• all arrangements are made to enable the initial configuration of the system to be restored in the event of failure (electrical, electronic, informatic),

• the first initiated fire alarm will not prevent any other detector to initiate further fire alarms.

.2 Installation requirements

.1 Manually operated call points shall be installed throughout the accommodation spaces, service spaces and control stations. One manually operated call point shall be located at each exit. Manually operated call points shall be readily accessible in the corridors of each deck such that no part of the corridor is more than 20 metres from a manually operated call point.

.2 Smoke detectors shall be installed in all stairways, corridors and escape routes within accommodation spaces.

.3 Where a fixed fire detection and fire alarm 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.

.4 Detectors shall be located for optimum performance. Positions near beams and ventilation ducts or other positions where patterns of airflow could adversely affect performance and positions where impact or physical damage is likely shall be avoided.

PART B FIRE SAFETY MEASURES

1 Structure (R 23)

NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

.1 The hull, superstructures, 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 II-2/A/2.7, the ‘applicable fire exposure’ shall be according to the integrity and insulation standards given in the tables of Regulations 4 and 5. 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 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.

.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 life-raft stowage, launching and embarkation areas, and ‘A’ and ‘B’ class divisions to ensure:

.1

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

.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 shall be of steel construction adequately insulated and openings therein, if any, shall be suitably arranged and protected to prevent the spread of fire.

2 Main vertical zones and horizontal zones (R 24)

NEW CLASS B, C AND D SHIPS:

.1.1 In ships carrying more than 36 passengers, the hull, superstructure and deckhouses shall be subdivided into main vertical zones by A-60 class divisions.

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.

NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

.1.2 For new class B, C and D ships carrying not more than 36 passengers and for existing class B ships carrying 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 divisions. These divisions shall have insulation values in accordance with the tables in Regulation 5.

NEW CLASS B, C AND D SHIPS:

.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. The length and width of main vertical zones may be extended to a maximum of 48 metres in order to bring the ends of main vertical zones to coincide with subdivision watertight bulkheads or in order to accommodate a large public space extending for the whole length of the main vertical zone provided that the total area of the main vertical zone is not greater than 1 600 m² on any deck. The length or width of a main vertical zone is the maximum distance between the furthermost points of the bulkheads bounding it.

NEW CLASS B, C AND D SHIPS AND EXISTING CLASS B SHIPS CARRYING MORE THAN 36 PASSENGERS:

.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 sprinkled 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 4.2 for new ships carrying more than 36 passengers, respectively table 5.2 for new ships carrying not more than 36 passengers and existing class B ships carrying more than 36 passengers.

.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 protection shall be obtained by dividing space in horizontal zones.

.2

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.

3 Bulkheads within a main vertical zone (R 25)

NEW CLASS B, C AND D SHIPS CARRYING MORE THAN 36 PASSENGERS:

.1.1 For new 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 4. All such divisions may be faced with combustible materials in accordance with the provisions of Regulation 11.

NEW CLASS B, C AND D SHIPS CARRYING NOT MORE THAN 36 PASSENGERS AND EXISTING CLASS B SHIPS CARRYING MORE THAN 36 PASSENGERS:

.1.2 For new ships carrying not more than 36 passengers and existing class B ships carrying 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 5.

If such divisions may be faced with combustible materials in accordance with the provisions of Regulation 11.

NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

.2 In new class B, C and D ships carrying not more than 36 passengers and in existing class B ships carrying more than 36 passengers 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;

.2

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 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.

.3

All bulkheads required to be ‘B’ class division, except corridor bulkheads prescribed in paragraph .2, shall extend from deck to deck and to the shell or other boundaries unless the continuous ‘B’ class ceilings or linings fitted on both sides of the bulkheads are at least of the same fire resistance as the bulkhead, in which case the bulkhead may terminate at the continuous ceiling or lining.

4 Fire integrity of bulkheads and decks in new ships carrying more than 36 passengers (R 26)

NEW CLASS B, C AND D SHIPS:

.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 4.1 and 4.2.

.2 The following requirements shall govern the application of the tables:

Table 5.2
Fire integrity of decks separating adjacent spaces
a For clarification as to which applies, see Regulations 3 and 8.
b Where spaces are of the same numerical category and superscript b 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.
c Bulkheads separating the wheelhouse and chartroom from each other may be ‘B-0’ rating.
d See paragraph .2.3 and .2.4 of this Regulation.
e For the application of Regulation 2.1.2, ‘B-0’ and ‘C’, where appearing in table 5.1, shall be read as ‘A-0’.
f Fire insulation need not be fitted if the machinery space in category (7) has little or no fire risk.
g 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. In ships, which are constructed on or after 1 January 2003, however, where a deck, except in a category (10) space, is penetrated for the passage of electric cables, pipes and ventilation ducts, such penetration shall be made tight to prevent the passage of flame and smoke. Divisions between control stations (emergency generators) and open decks may have air intake openings without means for closure, unless a fixed gas fire-fighting system is fitted. For the application of Regulation 2.1.2. an asterisk, where appearing in table 5.2, except for categories (8) and (10), shall be read as ‘A-0’.

6 Means of escape (R 28)

NEW CLASS B, C AND D SHIPS AND EXISTING CLASS B SHIPS:

.1 Stairways and ladders, corridors and doors shall be arranged to provide ready means of escape to the lifeboat and life-raft 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 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.

.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.

.4

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.

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.

NEW CLASS B, C AND D SHIPS OF 24 METRES IN LENGTH AND ABOVE CONSTRUCTED BEFORE 1 JANUARY 2003:

.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 life-raft embarkation decks, or to the uppermost deck if the embarkation deck does not extend to the main vertical zone being considered.

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:

.1

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).

.2

All stairways sized for more than 90 persons shall be aligned before and after.

.3

Such handrails shall be provided on both sides of longitudinal corridors more than 1,8 metres in width and transverse corridors more than 1 metre in width. Particular attention shall be paid to the need to be able to cross lobbies, atriums and other large open spaces along escape routes. Handrails and other handholds shall be of such strength as to withstand a distributed horizontal load of 750 N/m applied in the direction of the centre of the corridor or space, and a distributed vertical load of 750 N/m applied in the downward direction. The two loads need not be applied simultaneously.

.1.3 Escape routes shall not be obstructed by furniture or other obstructions. With the exception of tables and chairs which may be cleared to provide open space, cabinets and other heavy furnishings in public spaces and along escape routes shall be secured in place to prevent shifting if the ship rolls or lists. Floor coverings shall also be secured in place. When the ship is underway, escape routes shall be kept clear of obstructions such as cleaning carts, bedding, luggage and boxes of goods.

.1.4 Escape routes shall be provided from every normally occupied space on the ship to an assembly station. These escape routes shall be arranged so as to provide the most direct route possible to the assembly station, and shall be marked with symbols related to life-saving appliances and arrangements, adopted by IMO by Resolution A.760 (18).

.1.5 Where enclosed spaces adjoin an open deck, openings from the enclosed space to the open deck shall, where practicable, be capable of being used as an emergency exit.

.1.6 Decks shall be sequentially numbered, starting with ‘1’ at the tank top or lowest deck. These numbers shall be prominently displayed at stair landings and lift lobbies. Decks may also be named, but the deck number shall always be displayed with the name.

.1.7 Simple ‘mimic’ plans showing the ‘you are here’ position and escape routes marked by arrows shall be prominently displayed on the inside of each cabin door and in public spaces. The plan shall show the directions of escape, and shall be properly oriented in relation to its position on the ship.

14 Protection of special category spaces (R 37)

.1 Provisions applicable to special category spaces whether above or below the bulkhead deck

NEW CLASS B, C AND D SHIPS AND EXISTING CLASS B SHIPS CARRYING MORE THAN 36 PASSENGERS:

.1 General

.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 metres.

.2 The requirements of Regulations II-2/A/12, II-2/B/7 and II-2/B/9 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.

.2 Structural protection

.1 In new ships carrying more than 36 passengers the boundary bulkheads and decks of special category spaces shall be insulated to ‘A-60’ class standard. However, where an open deck space (as defined in Regulation 4.2.2(5)), a sanitary or similar space (as defined in Regulation 4.2.2(9)) or a tank, void or auxiliary machinery space having little or no fire risk (as defined in Regulation 4.2.2(10)), is on one side of the division the standard may be reduced to ‘A-0’.

Where fuel oil tanks are below a special category space, the integrity of the deck between such spaces may be reduced to ‘A-0’ standard.

.2 In new ships carrying not more than 36 passengers and existing class B ships carrying more than 36 passengers the boundary bulkheads of special category spaces shall be insulated as required for category (11) spaces in table 5.1 of Regulation 5 and the horizontal boundaries as required for category (11) in table 5.2 of Regulation 5.

.3 Indicators shall be provided on the navigating bridge which shall indicate when any fire door leading to or from the special category spaces is closed.

Doors to special category spaces shall be of such a construction that they cannot be kept open permanently and shall be kept closed during the voyage.

.3 Fixed fire-extinguishing system

Each special category space shall be fitted with an approved fixed pressure water-spraying system for manual operation which shall protect all parts of any deck and vehicle platform in such space.

In new class B, C and D ships constructed on or after 1 January 2003, such water spray systems shall have:

.1

a pressure gauge on the valve manifold;

.2

clear marking on each manifold valve indicating the spaces served;

.3

instructions for maintenance and operation located in the valve room; and

.4

a sufficient number of drainage valves.

The Administration of the flag State may permit the use of any other fixed fire-extinguishing system that has been shown by full-scale test in conditions simulating a flowing petrol fire in a special category space to be not less effective in controlling fires likely to occur in such a space. Such fixed pressure water-spraying system or other equivalent fire-extinguishing system shall comply with the provisions of IMO Resolution A.123 (V) and the IMO MSC/Circ. 914 ‘Guidelines when approving alternative water-based fire-fighting systems for use in special category spaces’ shall be taken into consideration.

.4 Patrols and detection

.1 An efficient patrol system shall be maintained in special category spaces. In any such space in which the patrol is not maintained by a continuous fire watch at all times during the voyage there shall be provided a fixed fire detection and fire alarm system of an approved type complying with the requirements of Regulation II-2/A/9. The fixed fire detection system shall be capable of rapidly detecting the onset of fire. The type and the spacing and location of detectors shall determined taking into account the effects of ventilation and other relevant factors.

In new class B, C and D ships constructed on or after 1 January 2003, after being installed the system shall be tested under normal ventilation conditions and shall give an overall response time to the satisfaction of the Administration of the flag State.

.2 Manually operated call points shall be provided as necessary throughout the special category spaces and one shall be placed close to each exit from such spaces.

In new class B, C and D ships constructed on or after 1 January 2003, manually operated call points shall be spaced so that no part of the space is more than 20 metres from a manually operated call point.

NEW CLASS B, C AND D SHIPS:

.1 Manually operated call points complying with the requirements of Regulation II-2/A/9 shall be installed.

.2 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.

.3 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.

.4 A public address system or other effective means of communication shall be available throughout the accommodation and service spaces and control stations and open decks.

In new class B, C and D ships constructed on or after 1 January 2003, this public address system shall comply with the requirements of Regulation III/6.5.

.5 NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

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 or she may be called upon to use. Each member of the fire patrol shall be provided with a two-way portable radio telephone apparatus.

NEW CLASS B, C AND D SHIPS:

.6 Ships carrying more than 36 passengers shall have the detection alarms for the systems required by Regulation 13.2 centralised in a continuously manned central control station. In addition, controls for remote closing of the fire doors and shutting down the ventilation fans, shall be centralised in the same location. The ventilation fans shall be capable of reactivation by the crew at the continuously manned control station. The control panel in the central control station shall be capable of indicating open or closed positions of fire doors, closed or off status of the detectors, alarms and fans. The control panel shall be continuously powered and should have an automatic changeover to standby power supply in case of loss of normal power supply. The control panel shall be powered from the main source of electrical power and the emergency source of electrical power defined by Regulation II-1/D/3 unless other arrangements are permitted by the regulations, as applicable.

.7 The control panel shall be designed on the fail-safe principle, e.g. an open detector circuit shall cause an alarm condition.

16 Upgrading of existing class B ships carrying more than 36 passengers (R 41-1)

In addition to the requirements for existing class B ships in this Chapter II-2, existing class B ships carrying more than 36 passengers shall comply with the following requirements:

.1

Not later than 1 October 2000:

.1

All accommodation and service spaces, stairway enclosures and corridors shall be equipped with a smoke detection and alarm system of an approved type, and complying with the requirements of Regulation II-2/A/9. Such system need not be fitted in private bathrooms, and spaces having little or no fire risk such as voids and similar spaces. Detectors operated by heat instead of smoke shall be installed in galleys.

.2

Smoke detectors connected to the fire detection and alarm system shall also be fitted above ceilings in stairways and corridors in the areas where ceilings are of combustible construction.

.3.1

Hinged fire doors in stairway enclosures, main vertical zone bulkheads and galley boundaries which are normally kept open shall be self-closing and be capable of release from a central control station and from a position at the door.

.3.2

A panel shall be placed in a continuously manned central control station to indicate whether the fire doors in stairway enclosures, main vertical zone bulkheads and galley boundaries are closed.

.3.3

Exhaust ducts from galley ranges in which grease or fat is likely to accumulate and which pass through accommodation spaces or spaces containing combustible materials shall be constructed of ‘A’ class divisions. Each galley range exhaust duct shall be fitted with:

.1

a grease trap readily removable for cleaning unless an alternative grease removal process is fitted;

.2

a fire damper located in the lower end of the duct;

.3

arrangements operable from within the galley for shutting off the exhaust fans;

.4

fixed means for extinguishing a fire within the duct; and

.5

suitably located hatches for inspection and cleaning.

.3.4

Only public toilets, lifts, lockers of non-combustible materials providing storage for safety equipment and open information counters may be located within the stairway enclosure boundaries. Other existing spaces within the stairway enclosure:

.1

shall be emptied, permanently closed and disconnected from the electrical system; or

.2

shall be separated from the stairway enclosure by the provision of ‘A’ class divisions in accordance with Regulation 5. Such spaces may have direct access to stairway enclosures by the provision of ‘A’ class doors in accordance with Regulation 5, and subject to a sprinkler system being provided in these spaces. However, cabins shall not directly open into the stairway enclosure.

.3.5

Spaces other than public spaces, corridors, public toilets, special category spaces, other stairways required by Regulation 6.1.5, open deck spaces and spaces covered by paragraph .3.4.2 are not permitted to have direct access to stairway enclosures.

.3.6

Existing machinery spaces of category (10) described in Regulation II-2/B/4 and back offices for information counters which open directly into the stairway enclosure may be retained, provided that they are protected by smoke detectors and that back offices for information counters contain only furniture of restricted fire risk.

.3.7

In addition to the emergency lighting required by Regulations II-1/D/3 and III/5.3, the means of escape including stairways and exits shall be marked, at all points of the escape route including angles and intersections, by lighting or photoluminescent strip indicators placed not more than 0,3 metres above the deck. The marking must enable passengers to identify all the routes of escape and readily identify the escape exits. If electric illumination is used, it shall be supplied by the emergency source of power and it shall be so arranged that the failure of any single light or cut in a lighting strip, will not result in the marking being ineffective. Additionally, all escape route signs and fire equipment location markings shall be of photoluminescent material or marked by lighting. The Administration of the flag State shall ensure that such lighting or photoluminescent equipment have been evaluated, tested and applied in accordance with the guidelines as given in IMO Resolution A.752 (18) or in ISO Standard 15370-2001.

.3.8
