You are looking at the fire extinguishers while conducting a safety audit for your business. What type of fire extinguisher is intended to extinguish electrical fires?

There are four main types of fire extinguishers, one for each type of flammable substance.
A for wood and paper fires.
B for flammable liquids.
C for electrical fires.
D (metal powder or NaCl [salt]) for flammable metals like phosphorus and sodium.
The multipurpose, or ABC-rated, extinguisher is currently the most common type of fire extinguisher. It has a dry chemical powder that cools and smothers the fire simultaneously. Make sure the fire extinguisher will work for Class C fires before using it to put out electrical fires, which may be caused by a shorted-out wire in a power supply.
