U.S. Coast Guard approved, marine-type fire extinguishers are required on boats where
a fire hazard could be expected from the engines or fuel system. Extinguishers are
classified by a letter and number symbol. The letter indicates the type of fire the unit is
designed to extinguish. Type B, for example, is designed to extinguish flaming liquids,
such as gasoline, oil, and grease. The number indicates the amount of the extinguishing
agent contained in the extinguisher; the higher the number, the greater the amount of
agent in the extinguisher.
U.S. Coast Guard approved extinguishers required for boats are hand-portable, have
either B-I or B-II classification, and must be provided with a mounting bracket. While
not required, it is recommended that the extinguishers be mounted in a readily accessible
location. Consider locations where the extinguisher can be reached easily; for example,
at or near the steering station or in the galley or engine room, but away from locations
where a fire may likely start.
One extinguisher can be approved for several different types of fires (A, B, or C). For
example, an extinguisher marked "Type A, Size II; Type B; C, Size I" is acceptable as a
Type B-I extinguisher.
Look for the section of the label that states "Marine Type USCG, Type A, Size II; Type
B; C Size I." (It will also contain a USCG approval number). Make sure Type B is
indicated. Hand-portable extinguishers will be either a Size I or II.
Size III and larger are too big for use on most recreational boats.
Fire extinguishers are required on boats when any of the following conditions exist:
Inspect extinguishers monthly to make sure that:
If the minimum weight is stated on the extinguisher label, weigh extinguishers annually
Fire extinguishers that do not satisfy the above requirements or that have been partially
emptied must be replaced or taken to a qualified fire extinguisher servicing company for
The following chart lists the number of fire extinguishers that are required on
recreational vessels. If a U.S. Coast Guard approved fixed fire extinguisher system
is installed for the protection of the engine compartment, the required number of
extinguishers may be reduced in accordance with the chart.
