Firefighting, damage control, and emergency response
Shipboard firefighting as practised, not as carried: the fire tetrahedron and what removing each leg does, the classes of fire and which agent suits each, AFFF and its film, CO2 and Halon 1301 in a machinery space, dry chemical extinguishers, setting fire boundaries, the firemain and hose-and-reel stations, and what flame, heat and smoke each do to a crew.

USCG Boatswain Manual Ch. 6 §6.1
Firefighting Shipboard fire is classified by fuel: A (combustibles), B (flammable liquids/gas), C (energised electrical), D (combustible metals — rare on small vessels), K (cooking oils — galley fires). Use the correct extinguisher class for the fuel.
46 CFR §177.405
General arrangement and outfitting. (a)The general construction of the vessel must be such as to minimize fire hazards insofar as it is reasonable and practicable. (b)Internal combustion engine exhausts, boiler and galley uptakes, and similar sources of ignition must be kept clear of and suitably insulated from combustible material. Dry exhaust systems for internal combustion engines on wooden or fiber reinforced plastic vessels must be installed in accordance with ABYC P-1 (incorporated by reference, see 46 CFR 175.600). (c)Machinery and fuel tank spaces must be separated from accommodation spaces by boundaries that prevent the passage of vapors. (d)Paint and flammable liquid lockers must be constructed of steel or equivalent material, or wholly lined with steel or equivalent material…
46 CFR §28.380
General structural fire protection. (a)Each vessel must be constructed so as to minimize fire hazards insofar as is reasonable and practicable. (b)An internal combustion engine exhaust, galley uptake, electrical heating tape, or similar source of ignition must be kept clear of and suitably insulated from combustible material. A dry exhaust system for an internal combustion engine on a wooden or fiber reinforced plastic vessel must be installed in accordance with ABYC P-1. (c)(1) Each accommodation space must be separated from machinery and fuel tank spaces by a fire resistant boundary which will prevent the passage of vapors. (2) Each pipe and cable penetration between an accommodation space and a machinery or a fuel tank storage space must be sealed. (d)Each vessel carrying paint and…

NAVEDTRA 14057 Ch. 13 — Aqueous Film-Forming Foam Fire ¶1
EXTINGUISHER (AFFF)—Used to provide a vapor seal over a small fuel spill, to extinguish small class BRAVO fires (such as deep-fat fryers), and for standing fire watch during hot work. AQUEOUS FILM-FORMING FOAM (AFFF)— AFFF, also known as “light water,” is a synthetic, film-forming foam designed for use in shipboard fire-fighting systems. AQUEOUS POTASSIUM CARBONATE (APC)— Are installed in Navy ships to provide protection for galley deep-fat and doughnut fryers and their exhaust systems. Aqueous potassium carbonate is specifically formulated to extinguish fire in the reservoirs by combining with the hot cooking oil surface to form a combustion-resistant soap layer, thereby cutting off the grease from its source of oxygen. AQUEOUS SOLUTIONS—A pH of 7 indicates a neutral solution; values belo…
NAVEDTRA 14057 Ch. 13 — Aqueous Film-Forming Foam Fire ¶2
BLOOD AGENTS—Chemical agents that enter the body through the respiratory tract. Most blood agents act rapidly and are normally nonpersistent. In general, a victim who does not die quickly will recover within a few hours. BLUEOUT—Acoustic reverberation (echoes) from underwater explosions (nuclear and conventional weapons) that masks the sounds sonar is supposed to detect. BOUNDARY (SPACES)—The outermost border or limit immediately surrounding a confined space, above, below, and on all sides, such as the outside walls of a fuel tank. BOX PATCH—Effective for use over holes that have jagged edges projecting inboard. BRAVO (B) FIRES—Those that occur in the vapor-air mixture over the surface of flammable liquids, such as gasoline, jet fuels, diesel oil, fuel oil, paints, thinners, solvents, lubr…
