In this tutorial, we will explore the foremost common classifications of fire extinguishers.

The first, and most common type of extinguisher is used for a Class A fire. These are fires fueled by ordinary combustible materials such as paper, wood, carbon, most plastics. The Class A fire extinguisher uses the water to smother the fire.

Class B fires are fueled by flammable liquids such as gasoline, kerosene, grease, and oil. Remember this classification extinguisher – think “B” for Boil, or oil. Class B extinguishers typically use liquid foam agent to smother the fire. You never want to use water on a Class B fire, as the water can cause the flammable liquids to spread like we accidentally drip water on a frying pan, and the grease pops, and in boiling liquid into the air.

Class C fires are fueled by electrical current traveling to wires, circuits, and outlets. Class C extinguishers most commonly use a dry chemical powder to smother the fire. In more sensitive environments such as a recording studio, a Class C extinguisher may use a halon gas that does not leave a residue. These are often referred to as clean agents. You would also never want to use water on a Class C fire for obvious reasons.

Most household extinguishers are a combination of Class A, B, and C ratings. These extinguishers can be used on ordinary combustible fires, liquid fires, and electrical fires.

The last of the four common classifications of fire is the Class D fire. The Class D fires fueled by combustible metals such as magnesium, potassium, and sodium. Class D fire extinguishers are used exclusively for Class D fires, and use materials such as sand, and dry chemical powders to smother the fire.

The incident happened at Dallas Airport on Sunday 24 July 2011. An American Airlines Boeing 777-200 apparently had an engine fire just after takeoff, and was forced to make a U-turn and dump fuel before performing an emergency landing. You can hear the pilot’s voice in the video hereafter as well as a part of the transcript:
