What fundamental practice should be employed when using a fire extinguisher?

Using the PASS method—Pull, Aim, Squeeze, and Sweep—is the essential and recognized technique for effectively operating a fire extinguisher. This standardized approach allows individuals to remember the correct steps to take quickly in an emergency situation.

• Pull the pin to unlock the extinguisher, which is a necessary first step to enable its use.
• Aim the nozzle at the base of the fire where the flames are originating, rather than at the flames themselves, which is crucial for effectively extinguishing the fire.
• Squeeze the handle to release the extinguishing agent; this creates a focused stream needed to combat the fire.
• Sweep from side to side at the base of the fire until it appears to be out, ensuring that the entire area is covered and reducing the chance of re-ignition.

This structured method enhances the likelihood of successfully extinguishing a fire while ensuring the user's safety. It is widely taught in fire safety training because it simplifies a potentially chaotic situation into manageable steps.
