What is the duration and range of the red-handle Halon extinguisher?

• A. Duration is 7 seconds; Range is 9 feet
• B. Duration is 9 seconds; Range is 11.5 feet
• C. Duration is 12 seconds; Range is 15 feet
• D. Duration is 5 seconds; Range is 5 feet

Answer: (B)

Discharge duration and reach are the practical limits you need to know for using a portable Halon extinguisher safely and effectively. The red-handle Halon extinguisher carried on most aircraft is designed to discharge for about 9 seconds and project the extinguishing agent roughly 11.5 feet from the nozzle. This combination gives you enough time to aim, sweep the area, and reach the fire without getting too close to the heat or smoke.

If a option suggests a shorter duration and shorter range, it wouldn’t provide sufficient coverage or reach to effectively tackle typical cabin fires. If it suggests a longer duration and longer range, it would exceed the standard operating spec for this handheld device. The 9 seconds and 11.5 feet values align with the standard specs for this extinguisher.
