Other fire hazardous spaces or equipment

1. Any galley deep fat frying installations is to be provided with a fixed fire extinguishing sys- tem designed and type approved according to ISO15371. The exhaust duct serving the deep fat frying installation is to be equipped with a fixed fire extinguishing system.

2. Petrol in limited volume(not more than 200 ) for auxiliary purposes may only be stored on open deck or in compartments effectively ventilated to open deck. The storage position is to be arranged that under no circumstances can inflammable or explosive fluids or gases accumulate, for example, in lower parts of the hull.

303. Fixed gas fire extinguishing system

1. General

(1) The use of a fire-extinguishing medium which, either by itself or under expected conditions of

use, will adversely affect as to endanger people, is

(2) The necessary pipes for

the earth's ozone layer, and/or gives off toxic gases in such quantities not to be permitted.

conveying fire-extinguishing medium into protected spaces are to be

provided with control valves so marked as to indicate clearly the spaces to which the pipes are led. Non-return valves are to be installed in discharge lines between cylinders and manifolds.

Suitable provision is to be made to prevent inadvertent admission of the medium into any

space.

(3) The piping for the distribution of fire-extinguishing medium is to be arranged, and discharge nozzles so positioned, that a uniform distribution of medium is obtained.

(4) Means are to be provided to close all openings which may admit air to, or allow gas to escape from, a protected space.

(5) Where the volume of free air contained in air receivers in any space is such that, if released in

such space in the event of fire, such release of air within that space would seriously affect the efficiency of the fixed gas fire-extinguishing system, the provision of an additional quantity of fire-extinguishing medium is to be required.

(6) Means are to be provided for automatically giving audible warning of the release of gas fire-ex- tinguishing medium into any space in which personnel normally work or to which they have access. The alarm is to operate for a suitable period before the medium is released, but not less than 20s. Visible alarm is to be arranged in addition to the audible alarm.

(7) The means of control of any fixed gas fire-extinguishing system are to be readily accessible and simple to operate, and are to be grouped together in as few locations as possible at positions not likely to be cut off by a fire in a protected space. At each location there are to be clear instructions relating to the operation of the system having regard to the safety of personnel.

(8) Automatic release of fire-extinguishing medium is not permitted. For a dedicated enclosure for gas turbines that are fitted in of yachts not engaged on international sea voyages, automatic re-

lease of fire-extinguishing medium inside the enclosures are taken to avoid any risk of automatic

release when persons are present in the protected space.

(9) Where the quantity of extinguishing medium is required to protect more than one space, the quantity of medium available need not be more than the largest quantity required for any one space so protected.

(10) Pressure containers required for the storage of fire-extinguishing medium are to be located out- side protected spaces in accordance with (13) below. Pressure containers may be located inside the space to be protected if in the event of accidental release persons will not be endangered.

(11) Means are be provided to safely check the quantity of medium in the containers.

(12) Containers for the storage of fire-extinguishing medium and associated pressure components are to be designed in accordance with Pt 5, Ch 5 of the Rules for Classification of Steel Ships with regard to their locations and maximum ambient temperatures expected in service.

(13) When the fire-extinguishing medium is stored outside a protected space, it is to be stored in a

room which is to be situated in a safe and readily accessible position and is to be effectively ventilated. Any entrance to such a storage room is preferably to be from the open deck, and in any case should be independent of the protected space. Access doors are to open outwards, and bulkheads and decks including doors and other means of closing any opening therein, which form the boundaries between such rooms and adjoining enclosed spaces, are to be gas tight. Such storage rooms are to be treated as control stations.

(14) Spare parts for the system are to be stored on board or at a base port.

(15) If the release of a fire extinguishing medium produces significant over or under pressurization in the protected space, means are to be provided to limit the induced pressures to acceptable limits to avoid structural damage.

2. Carbon dioxide systems

(1) For cargo spaces, the quantity of carbon dioxide available is, unless otherwise provided, to be sufficient to give a minimum volume of free gas equal to 30 % of the gross volume of the largest cargo space so protected in the craft.

(2) For machinery spaces, the quantity of carbon dioxide carried is to be sufficient to give a mini- mum volume of free gas equal to the 40 % of the gross volume of the largest machinery space protected, including the casing.

(A) For the purpose of this requirement, the volume of free carbon dioxide is to be calculated at 0.56 m kg.

(B) For machinery spaces, the fixed piping system is to be such that 85 % of the gas can be discharged into the space within 2 minutes.

(C) Two separate controls are to be provided for releasing carbon dioxide into a protected space

and to ensure the activation of the alarm. One control is to be used to discharge the gas from its storage containers. A second control is to be used for opening the valve of the piping which conveys the gas into the protected spaces.

(D) The two controls are to be space. If the box containing

located into the controls

a release box clearly identified for the particular is to be locked, a key to the box is to be in a

break-glass type enclosure conspicuously located adjacent to the box.

304. Fire pump, fire main, hydrant and fire hose

1. Fire pumps, and appropriate associated equipment, or alternative effective fire extinguishing systems are be fitted as follows.

(1) Class I yachts need only to have one fire pump installed. This fire pump is to be installed in the engine room or in an area of no fire hazard (void or tank compartment). The pump is to have a capacity of minimum 25 m h and be capable to producing a pressure of at least 0.27

MPa at the most remote hydrant when two fire hoses are in operation. The fire pump needs

only to be served by main power.

(2) Class II yachts are to comply with the above requirements in (1). In addition, an emergency fire pump of at least 15 m h is to be provided. This pump is to be capable of operation in-

dependent of main power supply and deliver a pressure of at least 0.27 MPa at the most remote hydrant when one fire hose is in operation. Portable emergency fire pump can be accepted if this can be deployed from stored position to operative position by one crewmember in less than 2 minutes.

(3) The arrangement of the pumps for Class II yachts is to be such that in the event of a fire in any one compartment all the fire pumps will not be put out of action.

(4) Isolating valves to separate the section of the fire main within the machinery space containing

the main fire pump or pumps from the rest of the fire main are to be fitted in an easily acces- sible and tenable position outside the machinery spaces. The fire main is to be so arranged that when the isolating valves are shut all the hydrants on the yacht, except those in the machinery space referred to above, can be supplied with water by a fire pump not located in this machi- nery space through pipes which do not enter this space. The spindles of manually operated valves are to be easily accessible and all valves are to be clearly marked. For a yacht not en- gaged on international sea voyages, isolating valves are not required if the fire pumps are lo- cated in areas of minor fire hazard. However valves are to be fitted to prevent the possibility that a failure in one fire pump of two or more fire pumps may the whole system out of service.

(5) Hydrants shall be so arranged so that any location on the yacht can be reached by the water jets from two fire hoses from two different hydrants, one of the jets being from a single length of hose.

(6) Minimum 3 fire hoses are to be provided for a class I yacht, and 4 for a class II. Hydrant and

hoses are to be installed in dedicated cabinets or clearly marked safety lockers. Fire hoses with a diameter exceeding 38 mm are not to be installed in accommodation areas unless the owner specifically defines another fire fighting philosophy.

(7) All hydrants onboard are to have the same diameter. All couplings on nozzles, hoses and hy- drants are to be interchangeable. A spanner is to be provided adjacent to each fire hydrant.

(8) Each fire hose is to be of non-perishable material and have a sufficient length to send water to protected space approved by the Society.

(9) Each fire hose is to be provided with a nozzle of an approved dual purpose type (i.e. spray/jet type) incorporating a shutoff.

(10) The fire main, including supports, couplings and valves are to be made of corrosion resistant

materials. Any part of the fire main inside areas of major fire hazard (engine room, tender

At least five portable extinguishers are to be provided, and so positioned, as to be readily available for immediate use. In addition, at least one extinguisher suitable for machinery space fires is to be positioned outside each machinery space entrance.

2. At least three 6 kg dry powder or 9 foam extinguisher, or equivalent types, are to be provided in corridors or stairways for each deck and each 20 m of accommodation. In addition, at least one

such extinguisher is to be installed in public spaces above 30 m and in any pantry. At least

306. Fire control plans

1. There are to be permanently exhibited, for the guidance of the operator and other people of the yacht, fire control plans showing clearly for each deck the following positions.

The control stations, the sections of the yacht which are enclosed by fire-resisting divisions together with particulars of the fire alarms, fire detection systems, the sprinkler installations, the fixed and portable fire-extinguishing appliances, the means of access to the various compartments and decks in the yacht, the ventilating system including particulars of the master fan controls, the positions of dampers and identification numbers of the ventilating fans serving each section of the yacht, the lo- cation of the international shore connection, if fitted, and the position of all means of control re- ferred to in Ch 1, 206. 3 and 301. 2. and 201. 1 and 301. 1 of this chapter.

The text of such plans is to be in the official language of the flag State. However, if the language is neither English nor French, a translation into one of those languages is to be included. Fire con- trol plans for a yacht not engaged on international sea voyages may not be included a translation of English or French language.

2. For Class II yachts, a duplicate set of fire control plans or a booklet containing such plans is to be permanently stored in a prominently marked weathertight enclosure outside the deckhouse for the assistance of shore side fire-fighting personnel.
