Planning to get a fire extinguisher? Excellent idea. That means you need to pay a visit to the local suppliers of fire extinguishers. While most are very helpful, if you want to make your trip to the suppliers of fire extinguishers extremely productive, it’s a good idea to know what kind of fire extinguisher you need beforehand.
Fires caused by ordinary combustible materials such as paper, wood, cardboard, and most plastics can be put out by a Class A extinguisher which contains water. If you check the numerical rating on a Class A extinguisher you will find that the cylinder contains information about the amount of water it holds and the magnitude of fire it can extinguish. If you’re at a location where a fire involving flammable or combustible liquids such as gasoline, kerosene, grease and oil a Class B extinguisher would be suitable. In this case, numerical ratings indicate how much of square feet of fire can be extinguished by this cylinder.
In case of fires involving electrical equipment including appliances, wires, circuit breakers and outlets the most important thing to remember is to avoid using water. Water is extremely dangerous in such situations as it can conduct electricity and there is a potential of getting an electric shock or even being electrocuted. In such cases, a Class C extinguisher, containing a non-conductive extinguishing agent, can be applied. Do note that Class C extinguishers don’t come with any numerical rating.
For fires that involve combustible metals, such as magnesium, titanium, potassium and sodium, a Class D fire extinguisher can be used. Such materials are normally used in chemical laboratories so there is no need to get a Class D extinguisher unless these are the materials you are handling through your work.
