We all should have one in all our household and cars. But which one is correct? Firstly we need to understand the different classes of fire so we can purchase the correct one. Tackling a fire with the wrong type of extinguisher can be in effective and dangerous.
South African classification of different fire types are listed below and define the extinguisher most appropriate to extinguish each.
CLASS A: Combustible solids
CLASS B: Flammable liquids & gases
CLASS C: Electrical equipment
CLASS D: Combustible metals
With this info we can go forward and a select an extinguisher to match the most appropriate fire we would most likely encounter around the house. I must point out from the beginning there is no extinguisher suited for all fires. But saying this there are some which would cover the three most likely types we could expect to encounter around the house. These been Class A /B/C.
Extinguishers include, water, foam, dry powder, CO2 and Halon. These each have a specific class of fire they are suited to. But the one I would suggest would be the Dry powder. Why you ask? Well the dry powder or D.C.P as it is commonly branded and called, is suited to extinguish three of the Classes of fire, namely A/B and C.
So we decided on type we would choose, now what size would be correct? This is a hard answer as there are no laws covering this for domestic households, but I recommend at least a 4.5kg for a standard house. This size you can be expected to put out a sizable fire and yet still be small enough to store where it does not deter on home décor.
