Does water float or sink when applied as fire extinguisher to a drum of burning liquids?

In MOST burning liquids, the water will sink, creating an explosion of steam as it become super-heated, causing the fire to spread rapidly.
Some aqueous film-forming fire extinguishers generate a foam that floats on the surface, smothering the fire.

Can a stored pressure water extinguisher be used to extinguishing all types of Class B fires.?
Certainly not ! Class B fires include petrol/oil fires as well as grease (chip pan) fires. Using a water extinguisher will not extinguish these types of fires because - since the flammable substance will float on water - it simply heats the applied water, turning it to steam - resulting in an explosive 'cloud' of burning vapour.

Should you use a fire extinguisher to put out a grease fire?
Yes, a fire extinguisher works on a grease fire. What you have to avoid with grease fires is throwing water on them, because the burning grease will just float on the water and will be splashed around as the water heats and vaporizes, spreading the fire, rather than being put out. But the carbon dioxide based fire extinguisher doesn't have that problem.
Why can liquids float on each other?
oil and water <><><> Some liquids, such as oil and water, do not mix- as they have different densities- so the lighter one (oil) will float on the heavier one.
