diesel fires?

Question

Can you extinguish a diesel fire using water, not a diesel tank on fire, but a pool of diesel , say 3m x 3m size ??

Answer 1

To answer your question ... yes, you can use water to put out a diesel fire. As previous folks have answered, there are better agents, but water, applied appropriately, will put out a pool of combustible liquid especially one as small as 3m x 3m.

To do this, you must use a heavy, wide angle, low pressure fog nozzle (i.e. Task Force automatic nozzle) in a brisk clockwise rotation. This application moving from one end of the pool to the other should be sufficient to extinguish a small fire. Larger fires will require foam application.

Answer 2

Yes, You use high velocity fog and Low Velocity fog to extinguish oil fires. It is a common technique on shipboard engine room fires.

Pools of burning oil do pose a safety issue if the oil temp is hot enough to boil water. This is the case in deep fat fryer fires (say that three times fast) where the entire depth of oil is very hot. a drop of water entering the oil flashes to steam and splashes the oil from the fryer causing it to mix with air and flash into flame....

However initial response to a diesel oil fire,(not a fryer) one can use low velocity fog to smother the fire as fine water particles are converted into steam displacing oxygen and cooling the flames. High velocity fog can be use to direct the burning surfaces into a smaller area and with co-ordinated hose work snuffed out either between two streams or in a corner.

Answer 3

Gasoline and oil fires are hard to put out with water because the oil floats and continues to burn, on top of the water.
Fire extinguisher gases can put out fires by blocking oxygen in the air, from the flame.

Class B Extinguishers should be used on fires involving flammable liquids, such as grease, gasoline, oil, etc. The numerical rating for this class of fire extinguisher states the approximate number of square feet of a flammable liquid fire that a non-expert person can expect to extinguish.

Answer 4

would have to be a fog spray to do it, but would more than likely spread fire. use a co2 extinguisher or foam, possibly a dry chem....foam works best for this type of fire....ie airliner fires....

Answer 5

do not use a co2 extinguisher as the force that it sprays at can actually cuase the spill to splash back at you always use either foam or sand
