Abstract
The present invention includes a system and method for detecting contaminated objects, for example mail pieces, through use of a pinching device that compresses the objects, thereby possibly releasing potential contaminant-containing particles into the air in a closed chamber. Whatever particles are in the closed chamber mix with the air in the closed chamber and form cavity air, which is captured by a detection and alert mechanism.
