What is the process of using fire extinguisher?

Using a fire extinguisher involves following a simple acronym called PASS:

1. Pull the pin: Pull the pin at the top of the fire extinguisher to break the tamper seal.

2. Aim the nozzle: Aim the nozzle or hose at the base of the fire, not at the flames themselves.

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

4. Sweep from side to side: Sweep the nozzle or hose from side to side at the base of the fire until it is completely extinguished.

Remember to always stand at a safe distance from the fire and never turn your back on it. If the fire is not extinguished after using the entire contents of the fire extinguisher, evacuate the area immediately and call the fire department.
