What must be done to barriers placed inside lines before closeout?

When discussing the necessary actions for barriers placed inside lines before a closeout, removing them is essential because the barriers are typically intended for temporary use to prevent foreign object debris (FOD) or contaminants during specific operations. Leaving these barriers in place could obstruct line functionality or compromise safety during operations.

Furthermore, once the task or operation requiring the barriers is complete, they must be removed to ensure that the area is clear for inspection and safe for use. This practice reinforces the importance of maintaining a clean and hazard-free environment at the closure of a task.

So, the focus on removal highlights not only procedural compliance but also safety and operational integrity, ensuring that any potential for FOD is mitigated before final operations are conducted.
