Understanding Class A Fires: Prevention and Safety Measures

Fire safety is a critical aspect of protecting lives and property, and one of the key components of fire safety is understanding the different classes of fires. In this blog post, we will explore Class A fires, which are one the most common types of fires. We’ll discuss what they are, the materials that fuel them, and most importantly, how to prevent and extinguish them.

What is a Class A Fire?

Class A fires are fires that involve ordinary combustibles, such as wood, paper, cloth, and plastics. These materials leave behind ash when burned, making them relatively easy to identify. Understanding the fuel source is crucial when it comes to selecting the right fire extinguisher and firefighting methods.

Common Fuel Sources for Class A Fires

1. Wood: The most common fuel for this type of fire is wood. This includes anything from furniture to building materials.

2. Paper: Paper, including books, documents, and cardboard, can ignite easily and sustain a fire.

3. Cloth: Fabrics, clothing, curtains, and upholstery are all potential fuel sources.

4. Plastics: Many everyday items, like plastic containers, toys, and even some electronics, can contribute to Class A fires.

What is a Class A Fire Extinguisher Used For?

A Class A fire extinguisher is a fire extinguisher designed specifically for tackling Class A fires, which involve ordinary combustibles like wood, paper, cloth, and plastics. This could be the likes of a Water fire extinguisher, Foam fire extinguisher or Powder fire extinguisher.

4. Kitchen Safety: In the kitchen, be mindful of cooking and never leave a hot stove unattended.

Extinguishing Class A Fires

When it comes to extinguishing Class A fires, using the correct fire extinguisher that is designed specifically for them is essential. Follow these steps:

1. Pull: Pull the pin to unlock the extinguisher.

2. Aim: Aim the nozzle or hose at the base of the fire.

3. Squeeze: Squeeze the handle to release the extinguishing agent.

4. Sweep: Sweep the nozzle or hose from side to side to ensure that the fire is completely extinguished.


Class A fires can be hazardous if not handled correctly. Prevention and proper fire safety measures are key to minimising the risk of such fires.
