1. Fixed contamination
Fixed contamination is contamination that cannot be
readily removed from surfaces.
It cannot be removed by casual contact, wiping,
brushing, or washing.
It may be released when the surface is disturbed
(buffing, grinding, using volatile liquids for cleaning,
construction, etc.).
Over time it may "weep," leach, or otherwise become
loose or transferable.
