What's the best type of extinguisher for the home? Best for snuffing out a molotov? All I have is BC. Do they make ABCD?
CO2 does a good job of removing the Oxygen from a gasoline fire. But you have to be pretty close to the fire, to point the extinguisher's horn at the base of the flames. Work the CO2 side to side, pushing back the flames until they are a narrow strip (getting smaller) on the far side. Unless you are wearing fire resistance gear, don't advance into to area you have under control, due to the danger of flash-over. With CO2, you have to work fast, because the tanks run out fast. This side-to-side application of CO2 works okay, WHEN nothing else is burning besides gasoline.
Dry chemical works on gas too, but the typical sizes people have at home, are not large enough for 16 oz of gasoline on fire over a 10' x 10' fire area.
The second method is using a water hose with a Fog nozzle, if it's just small mist type nozzle, then use the Shower setting. The idea is to COOL off the gas.
Using a narrow hard spray can spread the gas around, making the fire larger. But, if that's all you have.. Try it.
If someone throws a firebomb on the roof of your house, you will have to use a narrow spray nozzle just to reach the fire. If possible, adjust the spray so that it spreads out before contacting the flames. The water will drop the temperature and you might be able to put out the fire, before it eats into your attic.
Seems like standing in your front yard fighting your house fire, could open you to attacks from behind. So, having someone watching out for you as you work, might be worth thinking about.
