Foam fire extinguishers are used mainly for flammable liquid fires and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.
Yes, an energized electrical fire is Class C, so an ABC or BC fire extinguisher may be used safely.
because it conduct electricity
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 extinguisher that has only a green triangle on it would be a really BAD choice because it probably contains water for putting out Class A fires of ordinary combustibles. An electrical fire (Class C) is signified by the letter C in a blue circle. Or, you can turn off the electricity and use any extinguisher appropriate for the type of fire that was started by the electricity's heat.
red = water and is used for wood paper textiles and solid material fires. DO not use on liquid elictrical or metal fires. blue = powder and is used for liquid and electrical fires. DO not use on metal fires. yellow = foam and is used for liquid fires. DO not use on electrical or metal fires black = carbon dioxide (CO) and is used for liquid and electrical fires DO not use on metal fires. halon can be used on all fires as well as dry chemical
Foam spray extinguishers are not recommended for fires involving electricity, but are safer than water if inadvertently sprayed onto live electrical apparatus.

A Class A, B, C, or ABC fire extinguisher works wonders on several different types of fires. A is good for wood, paper, etc. B is good for liquids. C is good for electrical fires. Do not use a Class D, for these are best on metals (such as magnesium).
Soda water is used on general fires (wood, paper, etc). Foam is used on petrol or oil fires, to avoid spreading the fire. Carbon dioxide is used where there is electrical equipment, and there is a risk of electrocution. Then there is dry powder which is classed as a multi-purpose extinguisher.
There are several categories of fire extinguishers. It depends on where the extinguisher is likely to be used and on what type of fire is to be expected. For example: a soda and water extinguisher is commonly used for general type fires. But, due to the risk of being electrocuted, a soda and water extinguisher would be dangerous to use round high voltage electrical equipment - so a carbon dioxide extinguisher would be used instead. On oil fires, a foam extinguisher would be best, as a soda water extinguisher would simply spread the area of the oil fire, and even increase the intensity of the flames, while the foam would smother the flames, cutting off the oxygen to feed the fire.

A fire extinguisher is typically red, so it's easy to spot. It is marked with information identifying the type of extinguisher it is, such as dry powder or foam. It will also indicate the types of fires it is appropriate for.
