B on fire extinguishers generally means that it can be used to put out flammable liquid fires. B1 means it will do so, but not especially well (1 is the lowest ranking).
A is for flammable solids, C is for electrical fires.
Usually the number appears before the letter, so 1-B rather than B1. Properly used, a 1-B extinguisher can be reasonably expected to put out a puddle of flaming liquid about 2.5 square feet in area. If you've never had specific training in using one, you probably WILL NOT use it properly; for flammable liquid fires, unless it's an extremely small fire it's almost always better to call 911 than to try to use a fire extinguisher on it (you're more likely to spread it than extinguish it).
It refers to Class B fires, related to flammable/combustible liquids and gases.

B extinguishers are for putting out flammable liquids. These must be carried on boats.
what does the letter b on a b-1 fire extinguisher mean
Class B fire extinguishers are for fires of flammable liquids (grease, gasoline, oil, propane, paints). The numerical rating of "1" signifies the the number of square feet of the flammable fire that a non-expert could expect to put out.So, a B1 extinguisher will help put a flammable material fire on only one (1) square foot before it runs dry.
The B determines the type of fire that can be extinguished, and in this case it would be flammable liquids such as gasoline, grease, oil, diesel fuel, and kerosene. The number indicates the approximate number of square feet the unit can extinguish, so a B-1 would be a relatively small extinguisher.
The b-2 has about twice the capacity of a b-1.
it is on the B1 floor, on the table.
The answer depends upon whether the boat is under US or Canadian regulations, or something else, whether it is a motorboat, and how big it is, among other things. Not all boats are required to have a B1 fire extinguisher in the US or Canada.
