OSH Security Practice Test

The correct answer is based on the widely recognized PASS acronym, which is essential for effectively using a fire extinguisher in an emergency. The components of PASS break down as follows:

- **Pull**: Start by pulling the pin at the top of the fire extinguisher. This step ensures that the mechanism is ready for use.

- **Aim**: Next, aim the nozzle at the base of the fire. This is crucial because directing the extinguisher at the flames themselves will not extinguish the fire; you need to target the fuel source.

- **Squeeze**: Squeeze the handle or lever to release the extinguishing agent. This action generates the necessary pressure to expel the substance that will suppress the fire.

- **Sweep**: Finally, sweep the nozzle from side to side at the base of the fire, moving gradually closer as the flames diminish. This helps ensure that the extinguisher effectively covers the area of the fire.

Understanding and applying the PASS method can significantly improve one’s ability to respond to a fire emergency confidently and safely. Other options listed miss some of these critical components or include incorrect terminology that do not accurately represent the process for using a fire extinguisher effectively.
