A measure that prevents migration and entrapment of foreign object debris is called what?

The term that specifically refers to a measure that prevents migration and entrapment of foreign object debris (FOD) is FOD Protection. This concept encompasses various methods and systems designed to ensure that foreign objects do not become trapped in areas where they could cause harm, especially in aviation and other industries where safety is paramount.

FOD Protection includes physical barriers, regular cleaning procedures, and design considerations that minimize the likelihood of debris accumulation in critical areas. The goal is to create an environment where foreign objects are less likely to be present or able to move into positions that could pose a risk during operations.

In contrast, the other terms like FOD Management, FOD Prevention, and FOD Restriction each have their own meanings but do not directly capture the specific action of creating measures that directly inhibit the migration and entrapment of debris in the same way that FOD Protection does.
