What is the required run time of the AFFF Bilge Sprinkling System once lit off for a casualty?

Explanation:
Two minutes is the required run time. Activating the bilge sprinkling system for that duration ensures a sufficient foam blanket over the bilge area to cool surfaces, suppress vapors, and protect the casualty while responders take initial rescue actions. Shorter runtimes wouldn’t maintain the foam and cooling long enough to be effective, while longer runtimes waste foam and could delay other emergency steps. This two-minute duration is the standard you’d rely on to provide immediate, adequate protection during that critical phase after ignition.
