What action is necessary for leaks identified by witnesses?

The necessary action for leaks identified by witnesses is to investigate further. When a leak is reported, it is crucial to assess its severity, potential impact, and to gather more information to understand the situation fully. Investigating helps confirm the leak, determine its source, and evaluate any dangers or hazards it may create. This thorough approach ensures that appropriate measures can be taken to mitigate risks and address the issue effectively. Ignoring minor leaks may lead to larger problems later, while merely reporting to headquarters or requesting additional resources without proper investigation could result in a lack of understanding of the situation on the ground.
