Browse range. Types of fires The fire classification system categorises fires into groups based on the type of fuel involved. The below table sets out this class rating system- Classification Icon Fuel Type Class A Solids such as paper, wood, soft furnishings and plastic. Class B Flammable liquids such as paraffin, petrol and oil. Class C Flammable gases such as propane, butane and methane Class D Metals such as aluminium, magnesium and titanium Class F Cooking oils and fats Electrical Fires involving electrical apparatus.
Former Class E - this type of fire can fall into any of the classes, as it is not the electricity burning but the surrounding materials set alight by the electric current. Types of fire extinguishers Fire extinguishers are available in different types, with each one having specific fire classes that they are suitable for use on. They are not suitable for fires fuelled by flammable liquids or where electricity is involved.
The foam agent helps to prevent re-ignition. CO2 is not a conductor and does not leave behind any harmful residue. But no matter how many you have, nothing can substitute for the most important safety tool: a fire plan.
Make sure everyone in the family knows how to get out in a hurry, where to meet outside, and how to call Even if you think you've put out the fire on your own, don't cancel that emergency call. Leave it to the pros to decide if it's really out. Every household extinguisher is labeled A, B, or C, which tells you the types of fires the extinguisher is effective against.
A is ordinary combustibles like wood, paper, and cloth; B is flammable liquids, such as gasoline or cooking oil; and C is live electricity. In the fine print on the label, these letters are preceded by numbers — for example, 3-AB:C — which are the extinguisher's classification rating. The numbers, assigned by Underwriters Laboratories, tell the extinguisher's relative effectiveness against each type of fire, regardless of its weight or the chemical it uses.
The higher the number, the greater the effectiveness and likely the higher the price. So an extinguisher with a 4-A rating is more effective on ordinary combustibles than a 2-A one.
The C designation carries no number; it just means the extinguisher's chemicals won't conduct electricity. Fire safety experts advise you to learn how to use an extinguisher before an emergency arises. Check with your fire department to see if they offer homeowner training. Keep extinguishers where you can see and reach them easily, near the room's exit. That way you can fight the fire with your back to the door and make a quick escape if flames get out of control.
