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 letter B refers to Class B fires involving flammable liquids, such as fuel. The US Coast Guard regulations specify a series of extinguishers by their relative ability to extinguish increasing amounts of fire.
A B-I extinguisher (required on just about any powerboat) would correspond to the extinguishing characteristics of a UL listing 5-B:C, rated for 5 sq ft of liquid fire, with 2 pounds of dry chemical. However, B-I could also be a CO2 extinguisher with 4 pounds or a foam extinguisher with 6 quarts of capacity.
In addition to a B-I capacity, a marine extinguisher would also be required to have a USCG certification before it could be marketed or installed as USCG B-I.
A UL 1-B fire extinguisher, on the other hand, means it has a UL rating of 1-B. The unit will extinguish a 1 sq. ft. flammable liquid fire by a novice user.
For reference, a B-II has 5 pounds of dry chemical, or 15 pounds of CO2 or 10 quarts of foam.
