Abstract: A kit which can be ready to position in a containment fashion over a suspicious object or target. A chamber is formed having a surrounding wall with a mating top. At the lower portion of the wall a substrate engaging means is provided with lateral edges which are stabilized for securement to the surface on which the target lies while the chamber is brought into its full configuration by wall support means. At the upper portion of the top provision is made for handling sleeves and ports. Examination, sampling and decontamination can be carried out without disturbing the target while protecting the environment, evidence and people. The target can be encapsulated in the chamber by means of tightening a drawstring. This progressively brings the lower portion in the flange into and under the bottom of the contained item to thereby fully envelop the target. An explosive shield can be simultaneously employed.
