What does the PASS method refer to in using a fire extinguisher?

The PASS method is a crucial procedure for effectively using a fire extinguisher in an emergency situation. It stands for Pull, Aim, Squeeze, and Sweep, providing a clear and straightforward set of steps to follow for anyone who needs to extinguish a fire.

"Pull" refers to pulling the pin at the top of the fire extinguisher to unlock the mechanism. This is a necessary first step, as the pin secures the lever from being accidentally pressed.

"Aim" instructs you to point the nozzle at the base of the fire rather than at the flames. This is important because aiming at the base targets the fuel source of the fire, which is essential for effective extinguishment.

"Squeeze" means to squeeze the lever or handle slowly and firmly, which releases the extinguishing agent. This controlled release helps to ensure that the agent is dispensed effectively.

Lastly, "Sweep" involves sweeping the nozzle from side to side at the base of the fire, which helps to cover the area of the fire evenly and extinguish it completely.

Understanding these four steps is vital for anyone who may use a fire extinguisher, as it can significantly increase the chances of safely and effectively putting out a fire.
