Every home should have at least one portable fire extinguisher in their home that is easily accessible. Tips for your Fire Extinguisher. Fire Extinguishers are divided into four categories:

Class A which is for ordinary use such as paper, wood, and most plastics
Class B which is for flammable or combustible liquids like gasoline, kerosene, grease and oil
Class C which is for electrical equipment like with your appliances, outlets, circuit breakers
Class D which is for chemicals - this is typically found in chemistry labs

Only use a fire extinguisher if the fire is considered small. Never try and fight a big fire with a fire extinguisher or a fire that appears to be spreading quickly. In fact, you should know what is even burning in order to recognize which type of fire extinguisher to use; otherwise you are putting yourself in danger. Check that the gauge of your fire extinguisher is in the "green zone." This means it is charged. Not all extinguishers have pressure guages & not all that have them have a "green zone". Sometimes it is white or another colour. When using an extinguisher always have an exit at your back. Make sure you understand how to use the fire extinguisher before there might ever be a time to even use it. If you have a lot of smoke building up, get out quickly because carbon monoxide is the most deadly gas that is produced by a fire.
