Most premises should have a 2kg CO2 fire extinguisher as it is the "electrical extinguisher". Light and easy to use, they make no mess. Best combined with a water or AFFF spray, a 2kg carbon dioxide fire extinguisher can be used where electrical items are on fire but should not be used on Class A (paper, wood, cloth, etc) fires.

 

Types of fire include Class B (flamable liquids) and fires involving live electrical equipment. Anticipated lifespan with indoor use and maintenance - over 10 years
