Types of Fire Extinguishers & Their Uses: A Complete Guide

Fire safety is a crucial aspect of workplace and home protection. Choosing the right fire extinguisher can mean the difference between containing a fire and a disaster. But with multiple types available, how do you know which one is right for your needs? In this guide, we’ll break down the different fire extinguisher types, their uses, and when to use them.

Why Fire Extinguisher Types Matter

Different fires require different extinguishing agents. Using the wrong extinguisher can make a fire worse instead of stopping it. That’s why fire extinguishers are classified into five primary categories in the UK.

The 5 Main Types of Fire Extinguishers & Their Uses

1. Water Fire Extinguishers (Class A)

Best for: Fires involving solid materials like wood, paper, and textiles.

✅ Ideal for offices, schools, and warehouses.

2. Foam Fire Extinguishers (Class A & B)

Common in garages, fuel stations, and commercial buildings.

3. CO2 Fire Extinguishers (Class B & Electrical Fires)
