Foam fire extinguishers, or AFFF (Aqueous Film-Forming Foam) extinguishers, are effective for combating Class A and B fires. They create a film over the fuel surface, preventing oxygen from reaching the fire and suppressing the flames.

Foam extinguishers are versatile and can be used on solid combustible materials as well as flammable liquids like petrol and oil. However, they should not be used on electrical fires.

3. Dry Powder Fire Extinguishers:

Dry powder fire extinguishers are suitable for Class A, B, and C fires, making them highly versatile. They contain a fine powder that works by smothering the fire and interrupting the chemical reaction.

These extinguishers are effective on flammable gases, electrical fires, and various types of combustible materials. However, they can create a cloud of powder that may obscure vision and should be used with caution in enclosed spaces.

4. Carbon Dioxide (CO2) Fire Extinguishers:

CO2 fire extinguishers are designed for Class B and electrical fires. They work by displacing oxygen, effectively suffocating the flames. These extinguishers are particularly useful because they leave no residue and do not damage electrical equipment. However, they should not be used in confined spaces as the lack of oxygen can be hazardous to humans.

5. Wet Chemical Fire Extinguishers:

Wet chemical fire extinguishers are specifically designed for Class F fires, which involve cooking oils and fats.

They work by creating a soapy layer on the surface of the burning oil, preventing the release of flammable vapors and extinguishing the fire. Wet chemical extinguishers are also effective on Class A fires. However, they should not be used on electrical fires.

6. Specialist Fire Extinguishers:

In addition to the standard types of fire extinguishers, there are specialist extinguishers available for specific fire risks.

These include fire extinguishers for metal fires (Class D), such as those involving magnesium or lithium, and fire extinguishers for kitchen fires, which are designed to tackle cooking oil and fat fires, commonly found in commercial kitchens.

In the event of a fire emergency, having the knowledge and confidence to operate a fire extinguisher effectively can make a significant difference in safeguarding lives and property.

This step-by-step guide will provide you with the necessary instructions on how to properly use a fire extinguisher. Remember, never attempt to extinguish a fire unless it is safe to do so. Safety should always be your top priority.

  • Remember the PASS Technique

Step 1: Pull the Pin

The first step in using a fire extinguisher is to locate and pull the pin. This pin seals the extinguisher and prevents accidental discharge. Locate the pin near the handle, firmly grip it, and pull it out. The extinguisher is now ready to be used.


Step 2: Aim at the Base of the Fire

Once the pin is pulled, hold the extinguisher with both hands, ensuring a firm grip on the handle. Position yourself approximately six to eight feet away from the fire. Aim the nozzle or hose at the base of the fire, not at the flames. The base of the fire is where the fuel source is located, and targeting this area will help smother the fire effectively.


Step 3: Sweep Side to Side

With the nozzle or hose aimed at the base of the fire, squeeze the lever on the handle to discharge the extinguishing agent. Remember to keep your distance and avoid getting too close to the flames. Begin sweeping the extinguisher from side to side, covering the entire area of the fire. This motion helps to widen the coverage and ensures that the fire is thoroughly extinguished.


Step 4: Squeeze the Lever

While sweeping the extinguisher, it is crucial to maintain a continuous squeeze on the lever. This action allows the extinguishing agent to flow consistently and effectively onto the fire. Avoid short bursts as it may not be sufficient to extinguish the flames completely.
