Which type of fire extinguisher is most effective for putting out electrical fire? Correct Answer Carbon tetra chloride

A fire extinguisher, flame extinguisher or simply extinguisher is an active fire protection device used to extinguish or control small fires, often in an emergency situation.

Many types of fire extinguishers are available with different extinguishing 'agents' to deal with different classes of fires. 

Halon extinguishers:

• These extinguishers may be filled with carbon tetrachloride (CTC) and bromochlorodifluoro methene (BCF).
• They may be of either gas cartridge or stored pressure type.
• They are more effective in extinguishing small fires involving pouring liquids.
• These extinguishers are particularly suitable and safe to use on electrical equipment as the chemicals are electrically non-conductive.

Foam extinguishers:

These may be of stored pressure or gas cartridge types.

Foam extinguishers are most suitable for:

Must not be used where electrical equipment is involved.

Dry powder extinguishers:

• Extinguishers fitted with dry powder may be of the gas cartridge or stored pressure type.
• The main distinguishing feature is the fork-shaped nozzle.
• Powders have been developed to deal with class D fires.

Carbon dioxide (CO2):

• This type is easily distinguished by the distinctively shaped discharge horn.
• Suitable for class B fires
• Best suited where contamination by deposits must be avoided.
• Not generally effective in the open air.
