Disposable/portable decontamination unit

A portable decontamination enclosure unit comprising:

• a frame system comprising:
• (a) first and second opposing end members;
• each of said opposing end members comprised of a quadrilateral base member and side walls extending outwardly from said base member which collectively form an open-ended container;
• and
• (b) quadrilaterally disposed frame means comprised of vertically extendable telescoping members each having one end pivotally connected to a side wall of the first end member, and the other end slidably and pivotally connected to the corresponding side wall of the second end member;
• said quadrilaterally disposed frame means enabling the opposing first and second end members to be retracted to a closed position whereby said open-ended containers form an enclosure in which a bag member may be carried;
• said frame system forming a generally oblong configuration when in the extended position;
• a length of lay-flat material substantially impermeable to particulate material forming a bag member;
• said bag member being flexible and collapsible;
• said bag member being closed at one end, the other end having a rim edge defining an opening to receive said frame system;
• said bag member having a sufficient size to enclose said frame system when in the extended position;
• sealing means for sealing said rim edge whereby said bag member and enclosed extended frame system define a chamber area substantially impermeable to particulate material;
• and
• resealable means providing access to and egress from said chamber.
