An A/B/C extinguisher is best; you don't have to classify a fire before putting it out. For kitchen fires, you can get a B:C extinguisher containing sodium bicarbonate-or keep a box of baking soda handy at considerably less cost.

Halogen extinguishers are more expensive but come in small canisters that are easy to carry in a vehicle or on a belt clip. Halogen, a universal extinguisher, is best for fires in sensitive electrical or electronic equipment, as it is noncaustic and leaves no residue. However, halogen gas is suspected of contributing to depletion of the earth's ozone layer and should not be used indiscriminately. Extinguishers are also rated for size, capacity and discharge duration, indicated by the number 1, 2, or 3 preceding the A and B class ratings. The Kidde Fireway 340s we have are UL-rated 3A:40-B/C and weigh eight pounds (the heaviest we can manage effectively). Their cost of $40 is negligible compared to the lives and property they save. A 1-A:10-B/C extinguisher has a quarter or less of the capacity. But because most of the tangible value is in the metal canister and plastic valve mechanism, it doesn't weigh or cost much less than the larger models. Better too much capacity than too little. Get the largest extinguishers you can handle. The big ones come with a gauge and are rechargeable.
