What do the letters in the acronym "PASS" stand for when using a fire extinguisher?

The acronym "PASS" is a critical mnemonic for remembering the correct procedure to use a fire extinguisher effectively. Each letter corresponds to an essential action that ensures safety and maximizes the extinguisher's effectiveness when combating a fire.

Starting with "P," which stands for "Pull," this action refers to pulling the pin located at the top of the extinguisher. This pin prevents accidental discharge of the extinguisher and must be removed to begin using it.

Next, "A" indicates "Aim." This action involves aiming the nozzle at the base of the fire. It's important to focus on the source of the flames rather than the flames themselves, as addressing the fuel source is crucial to extinguishing the fire effectively.

Then comes "S," which means "Squeeze." This involves squeezing the handle to discharge the extinguishing agent. The correct technique here helps control the flow of the agent, allowing it to be released effectively.

Finally, the last "S" stands for "Sweep." This action entails sweeping the nozzle from side to side at the base of the fire to cover the area thoroughly. This sweeping motion is important for ensuring that the extinguishing agent reaches all parts of the fire and aids in its complete extinction.
