What does the acronym PASS stand for in fire extinguisher use?

The acronym PASS is a widely recognized method for using a fire extinguisher effectively and safely. Each letter corresponds to a crucial step in the process.

Starting with the first letter, "Pull," indicates that you should begin by pulling the safety pin from the handle of the extinguisher. This action releases the locking mechanism, allowing you to activate the extinguisher.

Next, "Aim" directs you to point the nozzle at the base of the fire. Targeting the base is important because it is where the fuel source is located, which needs to be extinguished to effectively put out the fire.

The third step, "Squeeze," instructs you to squeeze the handle or lever to discharge the extinguishing agent. This step needs to be done steadily to ensure a continuous flow of the agent towards the fire.

Finally, "Sweep" prompts you to sweep the nozzle from side to side at the base of the fire until it is completely out. This technique helps cover the area effectively and ensures that all flames receive the extinguishing agent.

Therefore, the correct answer encapsulates the essential actions to take when using a fire extinguisher in an emergency situation, promoting both safety and effectiveness in fire suppression.
