Which of the following statements is true concerning the fire extinguisher shown in the illustration? Illustration SF-0006

Correct Answer: Option A — The agent may be applied in short bursts by opening and closing the squeeze nozzle piece No.1.

Dry chemical extinguishers utilize a squeeze-grip nozzle that allows for intermittent discharge. This operational feature is critical for conserving the agent during a fire attack, enabling the operator to apply the powder in short, controlled bursts to effectively suppress flames without prematurely exhausting the unit's limited capacity.
