How long do HALON extinguishers typically last when in use?

HALON extinguishers are designed for quick and effective suppression of fires, particularly those involving flammable liquids and electrical equipment. When in use, they typically discharge for a duration of about 10 to 12 seconds. This duration is optimal for delivering a sufficient amount of the extinguishing agent to disrupt the combustion process without overwhelming the operator or compromising their ability to control the extinguisher.

The reason this specific time frame is essential is that it allows for a focused application of the HALON agent while ensuring that the firefighting effort can remain targeted. Since effectiveness can decrease with prolonged discharge due to dispersion and loss of pressure, the 10 to 12 seconds is considered a balanced duration for maximum efficiency. This standard aligns with the operational protocols typically taught in fire safety training, emphasizing the importance of quick and decisive action in firefighting scenarios.
