Foreign Object Debris

Foreign object debris or often known in the aviation industry as FOD is defined as a substance, debris or article alien to hardware or system which could potentially cause damage. The object may be foreign to an area or system and may be ingested by, or lodged in a mechanism. FOD objects are normally smaller items of debris; they are items that can be often over looked due to their obscure nature.  A few examples of foreign object debris can be something as simple as a pen a fallen bolt a staple from a note book a pair of tweezers or even a small animal!
