Fire extinguishers are one of the most important pieces of fire safety equipment in any home, office, factory, school, hospital, or commercial building. However, having a fire extinguisher is not enough—you must know which extinguisher to use for different types of fires.
Using the wrong extinguisher can make a fire worse, increase the risk of injury, or damage valuable equipment. This guide explains the different types of fire extinguishers, where they should be used, and why proper fire safety training is essential for every workplace.
Different fires require different extinguishing methods.

Our practical approach helps participants understand not only which extinguisher to use, but also how to respond confidently during a real emergency
Choosing the correct fire extinguisher is one of the most important aspects of fire safety.
Every extinguisher is designed for specific fire hazards, and using the wrong type can increase the risk instead of reducing it. By understanding fire classes, maintaining equipment, and providing regular employee training, organizations can improve emergency preparedness and create a safer environment for everyone.
The best fire extinguisher is not simply the one mounted on the wall—it is the one that is correctly selected, properly maintained, and used by a trained individual.
ABC Dry Chemical Powder extinguishers are commonly used in offices because they can handle several common fire types. CO₂ extinguishers are also widely used near electrical equipment.
No. Water should not be used on energized electrical fires because it can increase the risk of electric shock.
Wet Chemical extinguishers are specifically designed for cooking oil and fat fires.
Visual inspections should be carried out regularly, and servicing should follow the manufacturer’s recommendations and applicable regulations.
Training helps people identify the correct extinguisher, operate it safely, and understand when evacuation is the safest option.
