灭火器如何使用

To use a fire extinguisher, remember the acronym PASS:

1. Pull the pin: This will break the tamper seal and allow you to discharge the extinguisher.
2. Aim low: Point the nozzle or hose at the base of the fire, not the flames themselves.
3. Squeeze the handle: This will release the extinguishing agent.
4. Sweep from side to side: Move the extinguisher back and forth to cover the entire area of the fire with the extinguishing agent.

Remember to always stand at a safe distance from the fire and evacuate the area if the fire becomes too large or out of control.
