What does 'A' in the PASS acronym represent?

The 'A' in the PASS acronym stands for "Aim the nozzle at the base of the fire." This is a critical step in using a fire extinguisher effectively. Aiming at the base is important because this is where the fuel source is located, and targeting the base allows the extinguisher's contents to interrupt the combustion process directly. By aiming at the base, the extinguisher can suppress the fire more efficiently and prevent it from re-igniting.

Understanding the significance of this action ensures that individuals respond to fire emergencies correctly, maximizing the chance of extinguishing the fire before it spreads or becomes uncontrollable.
