Unfortunately, none. The classes of fire are A, B, C, D and K. However, the ABC extinguisher can be used for MOST fires. It is not effective on Class D fires (metals such as magnesium) and should not be used on large grease fires, such as a deep fat fryer (Class K). Most ABC extinguishers are a dry chemical type, such as ammonium tri-phosphate. You should avoid using those on sensitive electronic equipment (computers) due to damage to the equipment.
dry powder
Yes. They are rated for the type of fire they can be used against, and the capacity of the extinguisher.
You need to use a Class B extinguisher on flammable liquids.
Only the type of fire that is highlighted
A type A or Class A fire extinguisher is used on a Class A fire, that is, one involving "ordinary combustibles" such as paper, cloth, wood and small amounts of plastics.
What 'type' the fire is. The right extinguisher must be used for any fire. Or, more importantly - it can be very dangerous to use the wrong type of extinguisher, such as one with water should never be used on an electrical fire.
A Class A fire extinguisher should be used specifically for wood fires.
type B
powder or foam :)
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.
the kind that puts the freaking fire out
