What does the "A" in the PASS acronym signify?

The "A" in the PASS acronym stands for "Aim." PASS is a mnemonic used in fire safety training to help remember the steps for using a fire extinguisher effectively.

The first step, "Aim," refers to directing the extinguisher's nozzle at the base of the fire. This is crucial because aiming at the flames will not effectively extinguish the fire; instead, targeting the base allows the extinguisher to disrupt the fire's fuel source. Without proper aim, even the best fire extinguisher can be ineffective, so understanding this step is vital for ensuring safety and proper response in a fire emergency.

The other options represent concepts that are not part of the PASS acronym and do not align with the prescribed method for using a fire extinguisher.
