Zorluk: KolayEmergency Response Plan

A nurse is responding to a small paper fire in the staff break room. The fire alarm has been activated, and all personnel have been safely evacuated. The nurse retrieves a nearby fire extinguisher to contain the flames. Arrange the steps for operating the fire extinguisher in the correct priority sequence.

  1. 1Pull the pin from the handle of the fire extinguisher.
  2. 2Aim the extinguisher nozzle directly at the base of the fire.
  3. 3Squeeze the handle firmly to discharge the extinguishing agent.
  4. 4Sweep the nozzle from side to side until the fire is completely extinguished.

Cevap

The correct sequence for operating a fire extinguisher follows the PASS acronym: Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side.
The PASS mnemonic is the universal standard protocol for operating a portable fire extinguisher safely and effectively. The correct, logical sequence requires the user to first Pull the locking pin to enable the device, then Aim the nozzle at the base (fuel) of the fire, Squeeze the handle to release the agent, and finally Sweep the nozzle from side to side to thoroughly coat the fire area.

Adım Adım Çözüm

1
Pull the pin.
The extinguisher is unlocked and ready to use.
The tamper seal and locking pin prevent accidental discharge and must be removed first.
2
Aim the nozzle at the base of the fire.
The nozzle is directed at the fuel source.
Aiming at the flames themselves is ineffective; the extinguishing agent must coat the fuel source to remove the oxygen.
3
Squeeze the handle.
The extinguishing agent is released.
Depressing the lever activates the pressurized mechanism.
4
Sweep from side to side.
The base of the fire is completely covered with the extinguishing agent.
A sweeping motion ensures the entire area of the fire is blanketed and extinguished, preventing reignition.
