What is essential to prevent tools and their tethers from becoming FOD?

Frequent control and examination of tools and their tethers is essential to prevent them from becoming Foreign Object Debris (FOD) because it ensures that all equipment is regularly checked for any signs of damage or wear, which could contribute to FOD hazards. This practice allows for early identification of issues that may lead to tools being misplaced or dropped during operations. When tools are inspected frequently, workers are more aware of their immediate environment, which helps eliminate the risk of tools or their tethers being left in aircraft or work areas.

By understanding the condition and placement of tools through continuous examination, maintenance personnel are less likely to overlook potential FOD risks. It creates a culture of safety where all employees are encouraged to be vigilant and accountable for the tools they use. Regular observation not only mitigates the risk of FOD but also enhances overall safety and operational efficiency.

Other options, while they may contribute to a picture of good tool management, do not specifically address the proactive measures required to identify and mitigate FOD risks in the same immediate and hands-on way that frequent control and examination do.
