Types of Fires: Common Fire vs. Class A Fire

Fires can be classified into two main categories: common fires and Class A fires. Common fires are caused by combustible materials such as wood, paper, and plastic, while Class A fires are caused by combustible materials such as flammable liquids and gases. Each type of fire has its own characteristics and requires different extinguishing methods.

Characteristics of a Common Fire

Common fires are the most common type of fire and are caused by combustible materials such as wood, paper, and plastic. These fires are usually relatively easy to extinguish, as they don’t produce a lot of heat or smoke. Common fires are usually characterized by a yellow or orange flame and a moderate amount of smoke.

Characteristics of a Class A Fire

Class A fires are caused by combustible materials such as flammable liquids and gases. These fires are much more dangerous than common fires, as they produce a lot of heat and smoke. Class A fires are usually characterized by a blue or white flame and a large amount of smoke.

Extinguishing Methods for Common and Class A Fires

The most common method for extinguishing common fires is to use a fire extinguisher. Fire extinguishers are designed to smother the fire and stop it from spreading. For Class A fires, it is important to use a fire extinguisher designed specifically for flammable liquids and gases. Additionally, it is important to evacuate the area and call the fire department if the fire is too large to be extinguished with a fire extinguisher.
