Steam-propelled nautical school ships burning oil for fuel shall be fitted with the fire-fighting equipment of the following type and quantity:

(a) In each boiler room and in each of the machinery spaces of a nautical school ship propelled by steam, in which a part of the fuel-oil installation is situated, two or more approved 40-B fire extinguishers must be placed where accessible and ready for immediate use. On a nautical school ship of 1,000 gross tons and under, only one is required.

(b) In boiler and machinery spaces, at least two fire hydrants must have a firehose of a length that allows each part of the boiler and machinery spaces to be reached by water from a combination solid stream and water spray firehose nozzle.

(c) Each firehose under paragraph (b) of this section must have a combination solid stream and water spray firehose nozzle that meets subpart 162.027 of this chapter. Combination nozzles and low-velocity water spray applicators previously approved under subpart 162.027 of this chapter may remain so long as they are maintained in good condition to the satisfaction of the Officer in Charge, Marine Inspection.

(d) On every steam propelled nautical school ship of over 1,000 gross tons having one boiler room there shall be provided one 160-B fire extinguisher. If the nautical school ship has more than one boiler room, an extinguisher of the above type shall be provided in each boiler room. On every steam-propelled nautical school ship of 1,000 gross tons and under, a 120-B fire extinguisher may be used. Extinguishers fitted shall be equipped with suitable hose and nozzles on reels or other practicable means for easy access, and of sufficient length to reach any part of the boiler room and spaces containing oil-fuel pumping units.

(e) All nautical school ships propelled by internal-combustion engines shall be equipped with the following fire extinguishers in the machinery spaces:

(1) One 120-B fire extinguisher.

(2) One 40-B extinguisher for each 1,000 BHP of the main engines, or fraction thereof. The total number of fire extinguishers carried shall not be less than two and not more than six.

(3) When a donkey boiler fitted to burn oil as fuel is located in the machinery space, there shall be a 160-B fire extinguisher installed instead of the 120-B fire extinguisher.

(f) In this section, any reference to a fire extinguisher means approved by the Coast Guard.
