There is atype A (ordinary combustibles, leaving Ash),type B (flammable and combustible liquids),type C (conductive electrical equipment),type D (to put out burning metal), andtype K, used in commercial Kitchens for frying grease fires.
What type of fire extinguisher should you use for an electrical fire?
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.

Can fire extinguishers pressurized release burns the skin?
Absolutely - most fire extinguishers are either chemical or CO2 based, and any one of them can burn the skin. CO2 kills fires by removing heat, and as such is extremely cold when it comes out of the nozzle - that's why you see ice crystals on it.The only type that isn't much of a danger is the old water type that has a hose on it that you turn upside down - but it isn't pressurized.
