i. Fire fighting.

(1) The principal fire-fighting equipment consists of four motor-driven pumps, each with a capacity of 3,000 gallons per minute (gpm) and capable of 125 pounds pressure. (See fig. [13].) They are connected to an 8-inch fire main arranged on a loop circuit around the main deck. Spaced equally along this circuit are eight 2¹⁄₂-inch hydrants equipped with fog or spray nozzles. Throughout the ship are twenty-eight 1¹⁄₂-inch connections.

(2) There are two 1,000-gpm fire monitors. One is located forward on the forecastle head and the other is abaft the stack. (See figs. [1], [18], and [19].)
