If you already have a fire extinguisher at your home or office, or you’re considering getting one, you’ll need to know how it works in the event of an emergency. Fire extinguishers come in several designs and are most effective for putting out specific types of fires, so learn more about each variety to determine which is best for your needs.

What Type of Fire Extinguisher Do You Need?

1. Water & Foam

There are three elements needed to ignite a fire: fuel, heat, and an oxidizing agent, which is usually oxygen. A water and foam extinguisher works by eliminating the heat to break the triangle. This is best for Class A fires, or those that involve solid materials, so it’s a good choice for warehouses that store paper, textiles, or wood. However, remember to avoid using this for electrical fires, as water acts as a conductor.

2. ABC Dry Chemical

This extinguisher can put out Class A, B, and C fires. This includes those ignited by solids, electrical equipment, and flammable liquids, such as oils, diesel, or petrol. As a result, this variety is a popular choice among homeowners, as well as building managers.

3. Carbon Dioxide

This type of extinguisher works by removing the oxidizing agent in the fire triangle. Aside from that, its cold discharge can also help take away the heat. Carbon dioxide extinguishers are used for Class B and C fires, or those that involve flammable liquids and electrical equipment. Therefore, it's typically used when electrical fires break out in offices, because it doesn’t damage computers or leave any residue.
