While it can be tempting to save a few bucks by buying a smaller fire extinguisher – it might cost you a fortune when it runs out of material and a fire burns your property to the ground. It is very important to take into account the number when buying a fire extinguisher. That is a 20-B will cover 20 square feet and a 50-B will cover 50 square feet. Class B – the number on a Class B extinguisher is equivalent to the number of square feet you can cover with the agent.Class A – the number refers to the equivalent extinguishing power of a number of gallons of water in the extinguisher multiplied by a factor of 1.25, so a fire extinguisher marked 2-A holds 2.5 gallons of water extinguishing power and one marked 4-A holds 5 gallons.(That’s why it’s safe to use it on an electrical fire). The bigger the number, the more agent is available, and the bigger a blaze that you can tackle with that extinguisher.Ī Class C fire extinguisher has no such number because this classification simply attests that the material in the fire extinguisher is not an electrical conductor. That number relates to the amount of extinguishing agent is available in the fire extinguisher. Once you’ve examined the classes of fire extinguisher available to you – you will also note that before the A and B classifications most fire extinguishers will have a number. This is not optional, and your insurer should expect this as part of your insurance policies.Īlso read: Does Metal Burn In A Fire?
