Fire Extiguishers

Since this website is all about building a fire for indoor or outdoor warmth and cooking, it  makes sense to talk about fire extinguishers. Certainly safety cannot be overstressed.

Let's start with types of fires because this will determine what type of extinguisher should be on hand.

Class A   These consist of ordinary materials such as wood, paper ,plastic, fabric and trash. These are common accidental fires that occur across many industries and households. They can be extinguished with water or monoammonium phosphate.

Class B  These are fires fueled by a flammable liquid or gas.Common liquid fuels are petroleum based oils and paints or things like gasoline and kerosene.Butane and propane are common examples of gases that fuel Class B Fires. This type of fire is often encountered in industries that deal with fuels, lubricants, and/or certain paints. Common extinguishing methods include smothering to remove oxygen or producing a chemical reaction that does very much the same thing.

Class C  These are electrical fires.Examples are motors, appliances, and transformers.They are extinguished by using non-conducting chemicals.

Class D  These are fueled by combustible metals such as lithium, sodium, potassium, magnesium and others. Dry powder agents are required to extinguish this type.

Class K   These are cooking fires and are fueled by the liquids involve in food preparation.. They warrant their own classification and are caused by greases, oils and animal and vegetable fats used in cooking.

Fire extinguishers have ratings that show what type or types of fires they will extinguish. Many are rated for several different types of fire.

It pays to knpw!
