How long does Halon 1301 discharge for once activated?

Halon 1301, a commonly used fire suppression agent, has a discharge time that typically ranges from 3 to 15 seconds when activated. This duration is critical for effectively suppressing fires, particularly in environments where rapid extinguishment is necessary to protect both personnel and equipment.

The reason behind this specific range lies in the design and operational parameters of Halon systems. When a Halon 1301 system is activated, it quickly releases a concentrated volume of the agent to displace oxygen and interrupt the combustion process. The effectiveness of this rapid discharge is essential for dealing with fires in confined spaces, such as aircraft or server rooms, where traditional water-based extinguishing methods may not be applicable.

In summary, the correct answer reflects the operational characteristics of Halon 1301 systems, ensuring they deliver effective fire suppression in a timely manner. The other options do not accurately represent the typical operational discharge duration, which could lead to ineffective fire suppression in real-world applications.
