If a fire breaks out, you know the fundamental safety measures to take. There’s the “stop, drop, and roll,” using a blanket or cloth to contain the fire, and of course, water or a fire extinguisher. However, the team at GMW Fire Protection in Anchorage, AK, wants you to know there are many different types of fires to be aware of. Here, they explain the five main varieties and the commercial fire protection methods you can use to combat them.

Class A

A Class A fire is any fire caused or exacerbated by materials like fabric, paper, or wood. Although there are a variety of ways to attempt to put these fires out, the best commercial fire protection measure is a water extinguisher. These contraptions use a stream of water or mist to put out flames.

Class B

Class B fires are caused by combustible liquids and substances such as gas, oil, or diesel fuels. The best way to handle a Class B fire is with a carbon dioxide extinguisher. This tool doesn’t leave behind residue and is safe to use on most electrical appliances.

Class C

Fires involving gases are classified as Class C fires. Powder extinguishers are an effective way to put them out, and they can also be used on Class A and B fires. Powder extinguishers are known for decreasing visibility and causing brief respiratory problems for those in the vicinity, as they release a potent powder into the air.

Class D

Class D fires involve metals. Most extinguishers are capable of putting out a class D fire, including powder and carbon dioxide extinguishers.

Class E

Lastly, beware of Class E fires, or fires that involve burning oils—typically those found in the kitchen. Wet chemical extinguishers are best at putting out oil-based fires. The chemical suffocates the flame before cooling down the oil, creating a soap-like residue.
