What does the acronym PASS represent in relation to fire extinguishers?

The acronym PASS is critical for remembering the proper steps to use a fire extinguisher effectively. Each letter in PASS corresponds to an action:

• The first letter, P, stands for "Pull." This indicates the need to pull the pin on the extinguisher to ensure that it is ready for use. The pin prevents accidental discharge, so this step is essential.

• The second letter, A, represents "Aim." After the pin is pulled, you should aim the nozzle at the base of the fire. Targeting the base is crucial because this is where the fuel source is located, making it more effective in extinguishing the fire.

• The third letter, S, signifies "Squeeze." This action involves squeezing the handle slowly to release the extinguishing agent. It’s important to apply the right amount of pressure to control the discharge.

• The final letter, S, stands for "Sweep." This means moving the nozzle from side to side at the base of the fire. Sweeping ensures that the extinguishing agent blankets the fire effectively, helping to prevent re-ignition.

Understanding these steps helps ensure safety and efficiency when responding to a fire, making the use of the PASS acronym indispensable for anyone trained in fire safety.
