NaHCO3 and sodium Carbonate powder can be used as they readily converted into CO2 which acts as fire extinguisher.

Foam type extinguisher is used for oil type fire because it forms a layer on oil surface which prevents the oxygen to come in contact directly with oil called as smothering where as powder is used for metallic fire and the process is called free radical quenching. Here it is to be noticed that for preventing the fire the powder which is used is only for temporary purpose.

Even after receiving so many corrections why these people are not correcting the answer. It has to be FOAM, the powder is used in electric fire.
The reason is DENSITY of foam is lighter then petroleum element. So it forms a layer over the surface of the burning substance (petroleum) and cut offs the fire.

We know that petrol fire is not extinguish by the water and electric fire is not by water and foam it is extinguish by powder type, to extinguish the patrol fire we use foam type it cuts the link between the fire (patrol) from air.

Powder type is correct answer because this type of extinguisher is use high specific value of fuel i.e. petroleum , coal etc.

Petrolium products are oil & lubricants, we will use foam extiguiser, as it will make a foam cover over the oil and hence cut off the oxygen supply. Please correct the answer.
