FOD control

FOD control is the set of practices used to prevent, detect, remove, and document foreign objects in manufacturing, maintenance, and inspection areas. In industrial and aerospace settings, FOD commonly refers to both foreign object debris, meaning unwanted material in a work area or product, and foreign object damage, meaning damage caused by that material.

FOD control is commonly applied in quality-sensitive operations where loose hardware, tools, packaging, dust, wire clippings, or other unintended items could affect product conformity, equipment condition, or traceability. It may include tool accountability, area cleaning, part protection, visual checks, material segregation, operator instructions, and records of inspections or findings.

FOD control is related to housekeeping and 5S, but it is not the same thing. Housekeeping focuses broadly on workplace order and cleanliness. FOD control is specifically concerned with preventing foreign material from entering, remaining in, or damaging a product, assembly, machine, or controlled work zone.

In software-supported operations, FOD control may appear in digital work instructions, inspection checklists, nonconformance workflows, audit records, or maintenance documentation. These records help show that required checks were performed, but the term itself refers to the operational control process rather than to any specific software feature or certification outcome.
