Foreign Material Exclusion 

FMEForeign Material Exclusion refers to the process of preventing external items or debris from entering into areas where they can have safety or economic consequences. Foreign material can include dirt, broken parts, tools and rags. FME is important during periods of maintenance when plant components are opened up, as foreign material can be taken inside and left behind or dropped into the component. FME is applied in nuclear and process industries, in aerospace to prevent foreign material from entering aircraft components and in construction to avoid items being dropped from height.
