Foam spray extinguishers are not recommended for fires involving electricity, but are safer than water if inadvertently sprayed onto live electrical apparatus.
Electrical fire
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.

It is the Class C fires that invlove electrically energized equipments, and they are suppressed using CO2 extinguishers or dry chemical extinguishers. Certainly the use of water or water-based extinguishers or other water-based suppression equipment is not to be considered.
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.
Neither a gasoline or electrical fire should be put out by water. A gasoline fire should be put out by a fire extinguisher labeled A B C. An electrical fire should first have the power switched off. Then the fire extinguisher should be used.
Carbon dioxide, or foam, or dry powder. At no time should a soda water extinguisher be used, as the water will cause the burning gasoline to flare up and spread even further.
You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone. A CO2, dry chemical or "clean agent" (e.g., "Halogenated") extinguisher would be a better choice for an electrical fire, knowing that dry chemical powder will make quite a mess.
Water conducts electricity; therefore, using water to extinguish an electrical fire can result in electrocution.
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.
Yes. Depending on the type of fire and the type of extinguisher, you may simply spread the fire (which is bad enough) or you might actually cause more damage (trying to put out a sodium fire with a water based extinguisher, for example).
NO!!!!! Use a Dry Chemical extinguisher
