The 'usual' liquid of choice - is paraffin. It's much easier to control than other substances.

Since petroleum is a flammable liquid, a Class B fire extinguisher would be used.
Burning liquids such as gasoline, kerosene, paint, acetone, and so on.
A CO2 fire extinguisher will work on flammable liquid and electrical fires only. If used on any other type of fire they will just give it more oxygen and it will spread.
It is harder to start a combustible liquid buring than to start a flammable liquid burning. In most cases, however, neither type of liquid is "unstable." Both are simply liquids that can burn if ignited. Being "unstable" means that it might detonate or explode.
There is no liquid powder extinguisher on the market.
A type b extinguisher puts out a class B fire, i.e., flammable/combustible liquids and gases.
B-1 is for a Class B fire, that is, flammable/combustible liquids and gases.
Liquid
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).

Class 2 gas only means it's compressed and includes flammable/combustible, poisonous and inert (non-flammable, non-toxic) gases. You would only need a fire extinguisher for flammable gas, which is Class B.
