Spring summer and fall a 2-1/2 gallon class A pressurized water extinguisher with a cup of liquid dishwashing determinant will make an 20lb dry chem ABC or 10lb CO2 look like a toys on a class AB and even most C fires.
Water based liquid has the knock down and cool down that a poot of powder or CO2 can not accomplish. Re-ignition after knockdown with a CO2 and ABC dry chem is all to common. Nothing like watching your machine burn while holding an empty extinguisher after you thought the fire was out.
Winter time, stuck with the ABC or using antifreeze in the pressurized water unit.
