Diesel fires are considered Class B fires by firefighting professionals. These are all fires caused by flammable liquids. They are quite dangerous and cause many deaths each year. If you find yourself faced with a diesel fuel fire, here are a few hints to know beforehand to help you extinguish it.
Find the source of the fuel and shut it off. It will be very hard to put out the fire if it is constantly being fed new fuel.
Pull the pin on your fire extinguisher.
Aim the extinguisher on top of the fire. You want the smothering agents to fall over the top of the fire and smother it.
Squeeze the lever on the fire extinguisher.
Move the spray around the top of the fire. Dry chemical and foam extinguishers will leave a film across the top of the diesel fuel that keep the fire from flaring back up.
Keep an eye on the fire site for about half an hour to ensure there are no more flare ups.
