When considering materials for protection, what aspect should be taken into account to avoid FOD?

When prioritizing materials for protection against foreign object debris (FOD), visibility and detection are crucial factors. Materials that are easily identifiable can help ensure that any protective setups are effective in preventing FOD incidents. High visibility makes it easier for personnel to detect any items that may have the potential to be left behind or lost, thereby reducing the risk of such objects causing harm or interference later.

In the context of FOD management, the ability to promptly see and address any potential debris is essential, as it facilitates immediate action to mitigate risks. This is particularly important in environments where safety and operational efficiency are paramount, such as aviation and manufacturing.

While other options, such as cost and efficiency, durability and strength, or weight and size, also play a role in the selection of materials, they do not directly address the fundamental role that visibility and detection play in preventing FOD. Hence, focusing on visibility and detection provides a more immediate and practical approach to ensuring effective protection against foreign objects.
