The 4kg powder extinguisher is a popular all-rounder in the UK. Ideal for small industrial units with workshops as they cover all the types of fires. Powder can be messy but should only be used to prevent the spread of a more messy fire! They require factory refilling and testing or service-exchange (see NOTE).
Suitable for home, Portacabins, workshops, small industrial units, boats
Types of fire include Class A (wood, paper, cloth, etc), B (flamable liquids), C (gas - but never put out a gas fire if the gas cannot then be turned off) and safe around live electrical equipment
Anticipated lifespan with indoor use and proper maintenance - 10 years
NOTE - when a refill or test is due, at Fire Protection Online prices, it is cheaper to buy a new one
