SOLAS Ch. II-2, Part C, Regulation 10.2 – Water supply systems 2.3 Fire hoses and nozzles 2.3.1 General specifications 2.3.1.1 Fire hoses shall be of non-perishable material approved by the Administration and shall be sufficient in length to project a jet of water to any of the spaces in which they may be required to be used. Each hose shall be provided with a nozzle and the necessary couplings. Hoses specified in this chapter as "fire hoses" shall, together with any necessary fittings and tools, be kept ready for use in conspicuous positions near the water service hydrants or connections. Additionally, in interior locations in passenger ships carrying more than 36 passengers fire hoses shall be connected to the hydrants at all times.


SOLAS Ch. II-2, Part C, Regulation 10.2 – Water supply systems Fire hoses shall have a length of at least 10 m, but not more than: .1 15 m in machinery spaces; .2 20 m in other spaces and open decks; and .3 25 m for open decks on ships with a maximum breadth in excess of 30 m. 2.3.1.2 Unless one hose and nozzle is provided for each hydrant in the ship, there shall be complete interchangeability of hose couplings and nozzles.


SOLAS Ch. II-2, Part C, Regulation 10.2 – Water supply systems 2.3.2 Number and diameter of fire hoses

2.3.2.1 Ships shall be provided with fire hoses the number and diameter of which shall be to the satisfaction of the Administration.

2.3.2.2 In passenger ships, there shall be at least one fire hose for each of the hydrants required by paragraph 2.1.5 and these hoses shall be used only for the purposes of extinguishing fires or testing the fire-extinguishing apparatus at fire drills and surveys.


SOLAS Ch. II-2, Part C, Regulation 10.2 – Water supply systems 2.3.2 Number and diameter of fire hoses

2.3.2.3 In cargo ships: .1 of 1,000 gross tonnage and upwards, the number of fire hoses to be provided shall be one for each 30 m length of the ship and one spare but in no case less than five in all.

This number does not include any hoses required in any engine or boiler room. The Administration may increase the number of hoses required so as to ensure that hoses in sufficient number are available and accessible at all times, having regard to the type of ship and the nature of trade in which the ship is employed. Ships carrying dangerous goods in accordance with regulation 19 shall be provided with 3 hoses and nozzles, in addition to those required above; and .2 of less than 1,000 gross tonnage, the number of fire hoses to be provided shall be calculated in accordance with the provisions of paragraph 2.3.2.3.1. However, the number of hoses shall in no case be less than three.


SOLAS Ch. II-2, Part C, Regulation 10.2 – Water supply systems 2.3.3 Size and types of nozzles

2.3.3.1 For the purposes of this chapter, standard nozzle sizes shall be 12 mm, 16 mm and 19 mm or as near thereto as possible. Larger diameter nozzles may be permitted at the discretion of the Administration.

2.3.3.2 For accommodation and service spaces, a nozzle size greater than 12 mm need not be used.

2.3.3.3 For machinery spaces and exterior locations, the nozzle size shall be such as to obtain the maximum discharge possible from two jets at the pressure mentioned in paragraph 2.1.6 from the smallest pump, provided that a nozzle size greater than 19 mm need not be used.

2.3.3.4 Nozzles shall be of an approved dual-purpose type (i.e., spray/jet type) incorporating a shutoff.

Requirements on the

International Shore Connection

SOLAS Ch. II-2, Part C, Regulation 10.2 – Water supply systems 2.1.7 International sore connection 2.1.7.1 Ships of 500 gross tonnage and upwards shall be provided with at least one international shore connection complying with the Fire Safety Systems Code.

Requirements on FE’s inspections & service

Periodical checks requirements

Monthly: Fire mains, fire pumps, hydrants, hoses and nozzles

• verify all fire hydrants, hose and nozzles are in place, properly arranged, and are in serviceable condition;

• operate all fire pumps to confirm that they continue to supply adequate pressure; and

• emergency fire pump fuel supply adequate, and heating system in satisfactory condition, if applicable. (engineers )

Quarterly:

Verify international shore connection(s) is in serviceable condition.

Periodical checks requirements

Annually: Fire mains, fire pumps, hydrants, hoses and nozzles • visually inspect all accessible components for proper condition;

• flow test all fire pumps for proper pressure and capacity. Test emergency fire pump with isolation valves closed; (engineers )

• test all hydrant valves for proper operation;

• pressure test a sample of fire hoses at the maximum fire main pressure, so that all fire hoses are tested within five years;

• verify all fire pump relief valves, if provided, are properly set; (engineers )

• examine all filters/strainers to verify they are free of debris and contamination; (engineers )

and

• nozzle size/type correct, maintained and working.
