The Importance of FOD Signs

It is essential to any FOD program that the working environment be properly segmented and clearly marked according to FOD sensitivity. When in place, designated FOD area signs enable workers and visitors to properly identify the level of caution that should be employed in any area that is deemed to present a potential risk for foreign object contamination. FOD sensitive environments are generally segmented into 3 levels of sensitivity, each marked with their own distinct FOD signs.

FOD Awareness Areas…

…are at a low risk level for FOD incidents. In these areas there exists a low potential for hardware to be exposed to or invaded by foreign objects. Invasion by foreign objects would have minimal negative effects to form, fit, or function of hardware.

Hardware performance ability may be restricted, but still within operating parameters. Food and Drink are permitted in designated areas.

…are at a medium risk level for FOD incidents. In these areas there exists a medium potential for hardware to be exposed to or invaded by foreign objects, which could cause moderate damage to form, fit, or function of components, systems, or assemblies or cause sub-standard mission performance. Food and Drink are permitted in designated areas only.

…are at the highest risk level for FOD incidents. In these areas, a high potential exists for hardware to be exposed to or invaded by foreign objects, which could cause severe damage to form, fit, or function of components, systems, or assemblies, which could lead to product / vehicle deterioration, malfunction, and / or complete mission failure.

Human life may also be at risk. Food and Drink are not permitted in FOD critical areas. Depending on the environment, FOD suits (no pockets, zippers, or buttons) and FOD bags (to contain all personal effects) may be mandated.
