What is the proper discharge method for using an extinguisher?

The proper discharge method for using a fire extinguisher is encapsulated in the acronym PASS, which stands for Pull, Aim, Squeeze, and Sweep. This method ensures that users can efficiently and effectively operate a fire extinguisher when faced with a fire emergency.

The first step, pulling the pin, is essential because it unlocks the operating mechanism, allowing the extinguisher to function. Aiming the nozzle at the base of the fire is crucial, as this is where the fuel source is located and where the extinguishing agent can be most effective. Squeezing the handle releases the extinguishing agent, and this action must be done steadily to allow for controlled application. Finally, sweeping the nozzle from side to side helps cover the area of the fire, ensuring even distribution of the extinguishing agent and maximizing its impact on the flames.

By following this sequence, individuals can optimize their chances of successfully extinguishing a fire, demonstrating the importance of understanding and remembering the PASS technique when operating a fire extinguisher.
