How long does a Halon extinguisher typically last when in use?

A Halon extinguisher typically lasts about 10 seconds when in use. This duration is crucial for understanding how to effectively fight a fire. Halon extinguishers release a gas that displaces oxygen, effectively smothering the flames. Because the discharge time is relatively short, it emphasizes the importance of aiming the nozzle at the base of the fire and using short bursts to maximize the effectiveness of the extinguisher. Firefighting techniques involve quick, decisive actions that align with this time frame, allowing for the best chance of extinguishing a fire before it grows out of control. Understanding this aspect is essential for aircrew safety and preparedness in case of fire emergencies.
