In ships of less than 20m in breadth, the same section of detectors may serve spaces on both sides of the ship. In passenger ships fitted with individually identifiable fire detectors, a section may serve spaces on both sides of the ship and on several decks but shall not be situated in more than one main vertical zone.

2.4.2 Positioning of detectors
2.4.2.1 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. Detectors which are located on the overhead shall be a minimum distance of 0.5 m away from bulkheads, except in corridors, lockers and stairways.

2.4.2.2 The maximum spacing of detectors shall be in accordance with the table below:

2.1 Width of stairways

Ingangsdatum: 01-07-2002

2.1.1 Basic requirements for stairway width Stairways shall not be less than 900 mm in clear width. The minimum clear width of stairways shall be increased by 10 mm for every one person provided for in excess of 90 persons. 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 not be inferior to those determined by paragraph 2.1.2.

2.1.2 Calculation method of stairway width
2.1.2.1 Basic principles of the calculation
2.1.2.1.1This calculation method determines the minimum stairway width at each deck level, taking into account the consecutive stairways leading into the stairway under consideration.
2.1.2.1.2 It is the intention that the calculation method shall consider evacuation from enclosed spaces within each main vertical zone individually and take into account all of the persons using the stairway enclosures in each zone, even if they enter that stairway from another vertical zone.
2.1.2.1.3 For each main vertical zone the calculation shall be completed for the night time (case 1) and day time (case 2) and the largest dimension from either case used for determining the stairway width for each deck under consideration.
2.1.2.1.4The calculation of stairway widths shall be based upon the crew and passenger load on each deck. Occupant loads shall be rated by the designer for passenger and crew accommodation spaces, service spaces, control spaces and machinery spaces. For the purpose of the calculation the maximum capacity of a public space shall be defined by either of the following two values: the number of seats or similar arrangements, or the number obtained by assigning 2 square meters of gross deck surface area to each person.
2.1.2.2 Calculation method for minimum value
2.1.2.2.1Basic formulae In considering the design of stairway widths for each individual case which allow for the timely flow of persons evacuating to the muster stations from adjacent decks above and below, the following calculation methods shall be used (see figure 1 and figure 2):
when joining two decks: W=(N1+N2) 10mm;
when joining three decks: W=(N1+N2+0.5N3) 10mm;
when joining four decks: W=(N1+N2+0.5N3+0.25N4) 10mm;
when joining five decks or more decks the width of the stairways shall be determined by applying the above formula for four decks to the deck under consideration and to the consecutive deck,
where:
W = the required tread width between handrails of the stairway.
The calculated value of W may be reduced where available landing area S is provided in stairways at the deck level defined by subtracting P from Z, such that:
P = S 3.0 persons/ m ² ; Pmax = 0.25Z
where:
Z = the total number of persons expected to be evacuated on the deck being considered;
P = the number of persons taking temporary refuge on the stairway landing, which may be subtracted from Z to a maximum value of P = 0.25Z (to be rounded down to the nearest whole number) ;
S = the surface area ( m ² ) of the landing, minus the surface area necessary for the opening of doors and minus the surface area necessary for accessing the flow on stairs (see figure 1);
N = the total number of persons expected to use the stairway from each consecutive deck under consideration; N1 is for the deck with the largest number of persons using that stairway; N2 is taken for the deck with the next highest number of persons directly entering the stairway flow such that, when sizing the stairway width as each deck level, N1 > N2 > N3 > N4 (see figure 2). These decks are assumed to be on or upstream (i.e. away from the embarkation deck) of the deck being considered.

2 Engineering specifications

Ingangsdatum: 01-07-2002

2.1 General

Ingangsdatum: 01-07-2002

2.1.1 Throughout this chapter the term cargo tank includes also slop tanks.

2.1.2 The inert gas system referred to in chapter II-2 of the Convention shall be designed, constructed and tested to the satisfaction of the Administration. It shall be so designed * and operated as to render and maintain the atmosphere of the cargo tanks non-flammable at all times, except when such tanks are required to be gas-free. In the event that the inert gas system is unable to meet the operational requirement set out above and it has been assessed that it is impracticable to effect a repair, then cargo discharge, deballasting and necessary tank cleaning shall only be resumed when the "emergency conditions" laid down in the Guidelines on Inert Gas Systems are complied with ** .

2.1.3 Required functions
The system shall be capable of:
.1 inerting empty cargo tanks by reducing the oxygen content of the atmosphere in each tank to a level at which combustion cannot be supported;
.2 maintaining the atmosphere in any part of any cargo tank with an oxygen content not exceeding 8% by volume and at a positive pressure at all times in port and at sea except when it is necessary for such a tank to be gas-free;
.3 eliminating the need for air to enter a tank during normal operations except when it is necessary for such a tank to be gas-free; and
.4 purging empty cargo tanks of a hydrocarbon gas, so that subsequent gas-freeing operations will at no time create a flammable atmosphere within the tank.

* Refer to the Revised standards for the design, testing and locating of devices to prevent the passage of flame into cargo tanks in tankers (MSC/Circ.677) and the Revised factors to be taking into consideration when designing cargo tank venting and gas-freeing arrangements (MSC/Circ.450/Rev.1).

** Refer to the Clarification of inert gas system requirements under the Convention (MSC/ Circ.485) and to the Revised guidelines for inert gas systems (MSC/ Circ.353, as amended by MSC/Circ.387).
