                                          The purpose of this regulation is to suppress and swiftly extinguish a fire in the
                                             space of origin. For this purpose, the following functional requirements shall be
                                             met:
                                          
                                          
                                          
                                          2. Water supply systems
                                          
                                          Ships shall be provided with fire pumps, fire mains, hydrants and hoses complying
                                             with the applicable requirements of this regulation.

                                          2.1.1 General Materials readily rendered ineffective by heat shall not be used for
                                             fire mains and hydrants unless adequately protected. The pipes and hydrants shall
                                             be so placed that the fire hoses may be easily coupled to them. The arrangement of
                                             pipes and hydrants shall be such as to avoid the possibility of freezing. Suitable
                                             drainage provisions shall be provided for fire main piping. Isolation valves shall
                                             be installed for all open deck fire main branches used for purposes other than fire
                                             fighting. In ships where deck cargo may be carried, the positions of the hydrants
                                             shall be such that they are always readily accessible and the pipes shall be arranged
                                             as far as practicable to avoid risk of damage by such cargo.

.2.2 with a periodically unattended machinery space or when only one person is required
                                                   on watch, there shall be immediate water delivery from the fire main system at a suitable
                                                   pressure, either by remote starting of one of the main fire pumps with remote starting
                                                   from the navigating bridge and fire control station, if any, or permanent pressurization
                                                   of the fire main system by one of the main fire pumps, except that the Administration
                                                   may waive this requirement for cargo ships of less than 1,600 gross tonnage if the
                                                   fire pump starting arrangement in the machinery space is in an easily accessible position.
                                              
                                          
                                          
                                          2.1.3 Diameter of fire mains
                                          
                                          The diameter of the fire main and water service pipes shall be sufficient for the
                                             effective distribution of the maximum required discharge from two fire pumps operating
                                             simultaneously, except that in the case of cargo ships the diameter need only be sufficient
                                             for the discharge of 140 m3/h.
                                          
                                          2.1.4 Isolating valves and relief valves
                                          
                                          2.1.4.1 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 shall
                                             be fitted in an easily accessible and tenable position outside the machinery spaces.
                                             The fire main shall be so arranged that when the isolating valves are shut all the
                                             hydrants on the ship, except those in the machinery space referred to above, can be
                                             supplied with water by another fire pump or an emergency fire pump. The emergency
                                             fire pump, its seawater inlet, and suction and delivery pipes and isolating valves
                                             shall be located outside the machinery space. If this arrangement cannot be made,
                                             the sea-chest may be fitted in the machinery space if the valve is remotely controlled
                                             from a position in the same compartment as the emergency fire pump and the suction
                                             pipe is as short as practicable. Short lengths of suction or discharge piping may
                                             penetrate the machinery space, provided they are enclosed in a substantial steel casing,
                                             or are insulated to A-60 class standards. The pipes shall have substantial wall thickness,
                                             but in no case less than 11 mm, and shall be welded except for the flanged connection
                                             to the sea inlet valve. 
                                          
                                          2.1.4.2 A valve shall be fitted to serve each fire hydrant so that any fire hose may
                                             be removed while the fire pumps are in operation.
                                          
                                          2.1.4.3 Relief valves shall be provided in conjunction with fire pumps if the pumps
                                             are capable of developing a pressure exceeding the design pressure of the water service
                                             pipes, hydrants and hoses. These valves shall be so placed and adjusted as to prevent
                                             excessive pressure in any part of the fire main system.
                                          
                                          2.1.4.4 In tankers, isolation valves shall be fitted in the fire main at poop front
                                             in a protected position and on the tank deck at intervals of not more than 40 m to
                                             preserve the integrity of the fire main system in case of fire or explosion.
                                          
                                          2.1.5 Number and position of hydrants
                                          
                                          2.1.5.1 The number and position of hydrants shall be such that at least two jets of
                                             water not emanating from the same hydrant, one of which shall be from a single length
                                             of hose, may reach any part of the ship normally accessible to the passengers or crew
                                             while the ship is being navigated and any part of any cargo space when empty, any
                                             ro-ro space or any vehicle space in which latter case the two jets shall reach any
                                             part of the space, each from a single length of hose. Furthermore, such hydrants shall
                                             be positioned near the accesses to the protected spaces.
                                          
                                          2.1.5.2 In addition to the requirements in the paragraph 2.1.5.1, passenger ships
                                             shall comply with the following:

                                                   in any one compartment could put all the pumps out of action, there shall be an alternative
                                                   means consisting of an emergency fire pump complying with the provisions of the Fire
                                                   Safety Systems Code with its source of power and sea connection located outside the
                                                   space where the main fire pumps or their sources of power are located.
                                              
                                          
                                          
                                          2.2.3.2 Requirements for the space containing the emergency fire pump
                                          
                                          2.2.3.2.1 Location of the space
                                          
                                          The space containing the fire pump shall not be contiguous to the boundaries of machinery
                                             spaces of category A or those spaces containing main fire pumps. Where this is not
                                             practicable, the common bulkhead between the two spaces shall be insulated to a standard
                                             of structural fire protection equivalent to that required for a control station
                                          
                                          2.2.3.2.2 Access to the emergency fire pump
                                          
                                          No direct access shall be permitted between the machinery space and the space containing
                                             the emergency fire pump and its source of power. When this is impracticable, the Administration
                                             may accept an arrangement where the access is by means of an airlock with the door
                                             of the machinery space being of A-60 class standard, and the other door being at least
                                             steel, both reasonably gastight, self-closing and without any hold back arrangements.
                                             Alternatively, the access may be through a watertight door capable of being operated
                                             from a space remote from the machinery space and the space containing the emergency
                                             fire pump and unlikely to be cut off in the event of fire in those spaces. In such
                                             cases, a second means of access to the space containing the emergency fire pump and
                                             its source of power shall be provided.

                                          Ventilation arrangements to the space containing the independent source of power for
                                             the emergency fire pump shall be such as to preclude, as far as practicable, the possibility
                                             of smoke from a machinery space fire entering or being drawn into that space.
