In what manner should a Water Glycol fire extinguisher be discharged?

1. Quick bursts

2. In a continuous motion

3. Short pulses

4. Intermittent spraying

The correct answer is: In a continuous motion

Discharging a Water Glycol fire extinguisher in a continuous motion is effective because it ensures a steady application of the extinguishing agent, which is critical when combating certain types of fires, particularly those involving flammable liquids and specific combustible materials. The continuous discharge maintains a protective barrier against the flames and effectively cools the burning material to extinguish the fire. Using a continuous motion allows for even distribution of the agent, which helps to prevent re-ignition and ensures thorough coverage of the affected area. This method contrasts with quick bursts or short pulses, which may not deliver enough agent to adequately suppress the flames or could allow the fire to re-flare. Intermittent spraying could lead to the same issue where the flames might not be fully extinguished before the extinguisher runs out or loses efficacy. Therefore, continuous motion is the most effective and recommended technique for using a Water Glycol fire extinguisher.
