Remember "P.A.S.S." for Easy Recall

"P.A.S.S." is a simple mnemonic to remember the four key steps in operating a fire extinguisher:

• Pull the pin
• Aim at the fire's base
• Squeeze the handle
• Sweep side to side

Safety First

Before using a fire extinguisher, ensure everyone's safety and call the fire department for large or spreading fires. Note that fire extinguishers are designed for small fires only. If the fire grows quickly, evacuate and wait for professional assistance.

Using a Fire Extinguisher: Step-by-Step

1. Pull the Pin: The pin at the top of the extinguisher prevents accidental discharge. Remove it to activate the extinguisher.

2. Aim at the Fire's Base: Direct the nozzle or hose at the fire's base. Targeting the base tackles the fire's source, not just the visible flames.

3. Squeeze the Handle: This releases the extinguishing agent, which could be powder, foam, or carbon dioxide, depending on the extinguisher type.

4. Sweep Side to Side: While holding down the handle, sweep the extinguisher side to side, covering the fire's base. Continue even if the flames seem to diminish, ensuring the fire source is completely out.

Post-Extinguishing Measures

After extinguishing the fire, remain vigilant for any signs of reignition. If the fire relights, attempt to extinguish it again or evacuate and contact the fire department.

Understanding Extinguisher Limitations

It's crucial to recognize that fire extinguishers are only effective on small fires. They are not suitable for large or fast-spreading fires. Additionally, different types of fires require specific extinguishers, such as using a particular extinguisher for grease fires versus electrical fires.

In summary, knowing how to operate a fire extinguisher is vital for containing small fires and preventing them from escalating. Use the "P.A.S.S." method: pull the pin, aim at the base, squeeze the handle, and sweep side to side. Always be aware of the extinguisher's limitations and call for professional help if the fire becomes unmanageable.
