1. Pull, Aim, Squeeze, Sweep

2. Push, Assess, Secure, Shift

3. Pull, Align, Stop, Secure

4. Push, Activate, Squeeze, Sweep

The correct answer is: Pull, Aim, Squeeze, Sweep

The PASS system is a critical acronym used during fire safety training that stands for Pull, Aim, Squeeze, and Sweep. This set of instructions provides a clear and easy way to remember the proper procedure for using a fire extinguisher effectively. The first step, "Pull," refers to pulling the safety pin from the handle of the extinguisher. This pin prevents accidental discharge, and removing it ensures that the extinguisher is ready to operate. The second step, "Aim," instructs the user to direct the nozzle of the extinguisher toward the base of the fire. Aiming at the base is crucial because fires need fuel to be extinguished effectively, and targeting the source helps cut off its fuel supply. The third step, "Squeeze," involves squeezing the handle of the extinguisher to release the extinguishing agent. This action activates the extinguisher, allowing the user to control the release of the material meant to combat the fire. The final step, "Sweep," entails sweeping the nozzle side to side while maintaining the aim at the base of the fire. This technique ensures an even distribution of the extinguishing agent over the burning area. Understanding the PASS system is essential for anyone handling a fire extinguisher
