Fire extinguishers are often the first line of defense in stopping flames that arise in a home, business, or restaurant. However, not all devices have the same purpose, as various classes target different fires. Here's what you should know to ensure you use this equipment properly and safely.

Main Types of Fire Extinguishers

Fire extinguishers are designated based on the type of incident they are equipped to put out. Many are multipurpose, such as ABC or BC, meaning they can handle more than one kind of fire. Here are the different classifications for these safety devices:

• Class A Fires: Caused by standard combustible materials, such as wood and paper. 
• Class B Fires: Stem from flammable liquids, such as paint, oil, or gas. 
• Class C Fires: Started by electrical items, such as wiring or motors.
• Class D Fires: Caused by flammable metals, such as magnesium or sodium.
• Class K Fires: Arise from kitchen materials, such as cooking oils or grease.

Residential and commercial properties will mainly utilize a multipurpose unit that can target class A, B, and C fires, which are the most common. This fire extinguisher removes the chemical reaction responsible for starting the incident.
