What is the proper operation sequence of a fire extinguisher?

• A. Pull, Aim, Squeeze, Sweep (PASS)
• B. Turn, Aim, Squeeze, Sweep
• C. Pull, Squeeze, Aim, Sweep
• D. Inspect, Aim, Squeeze, Sweep

Answer: (A)

The proper operation sequence of a fire extinguisher is "Pull, Aim, Squeeze, Sweep," commonly known by the acronym PASS. To elaborate on this sequence: - **Pull** refers to removing the safety pin that prevents accidental discharge. This step is critical as it enables the user to operate the extinguisher effectively. Without removing the pin, the extinguisher will not function. - **Aim** involves pointing the nozzle at the base of the fire. Targeting the source of the flames is essential for effectively extinguishing the fire, as aiming at the flames themselves will usually be ineffective. - **Squeeze** means pressing down on the handle to release the extinguishing agent. This step is necessary to activate the extinguisher and allow the agent to flow out. - **Sweep** involves moving the nozzle from side to side at the base of the fire. This sweeping motion helps ensure that the extinguishing agent covers the area thoroughly, thereby smothering the flames effectively. This sequence is important for safely and effectively using a fire extinguisher, ensuring that users can respond quickly and correctly in emergency situations. Other sequences do not represent the correct operational procedure and would likely lead to ineffective or unsafe use of the fire exting
