The acronym PASS stands for Pull, Aim, Squeeze, Sweep, which is a critical procedure for effectively using a fire extinguisher. Understanding each component is essential for ensuring that the user can operate the extinguisher safely and efficiently during a fire emergency.

- **Pull** refers to pulling the safety pin from the extinguisher's handle. This step is crucial as it unlocks the operating mechanism and allows for the extinguisher to be activated.

- **Aim** means to point the nozzle or hose at the base of the fire, where the flames are located. Aiming at the base is essential for effectively extinguishing the source of the fire rather than just spraying foam or liquid above the flames, which might not be effective.
