What does the 'A' in the PASS method for using a fire extinguisher signify?

The 'A' in the PASS method for using a fire extinguisher signifies "Aim the nozzle towards the base of the fire." This is crucial because aiming at the base of the fire is where the fuel source is located, and it's essential to extinguish the flames effectively. When using an extinguisher, directing the extinguishing agent at the base helps to eliminate the fire at its source, rather than just dispersing the agent through the flames, which may be ineffective.

Properly aiming at the base of the fire increases the chances of successfully putting it out, as it disrupts the combustion process directly and prevents re-ignition. This action is part of the systematic approach of the PASS method, which is designed to aid individuals in operating a fire extinguisher effectively and safely.
