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.
It will put out burning fluids.

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.
B extinguishers are for putting out flammable liquids. These must be carried on boats.
