Fire is contained

Horn is nonmetallic

A carbon dioxide (CO2) fire extinguisher works by displacing the oxygen needed for combustion to take place. In electrical fires, it is important to use non-conductive materials to avoid the risk of electrocution. Therefore, the non-metallic horn on a CO2 extinguisher makes it a safe choice for use on electrical fires. The other options are incorrect because

A) The fire does not need to be contained for the extinguisher to be effective.

C) While wearing gloves may provide additional protection, it is not necessary when using a CO2 extinguisher on electrical fires.

D) A fully charged extinguisher is always recommended but is not the sole determining factor for its effectiveness on an electrical fire.
