A triage cubicle assembly comprises an enclosure of foldable material sufficiently large to accommodate a disaster victim and at least one other person when deployed, the enclosure being releasably attachable to an external overhead frame for support, and having a floor configured to have a portion overlie a victim-supporting surface higher than the floor and external to the enclosure. In the preferred embodiment, the external overhead canopy frame is collapsible, and the victim-supporting surface is a table-like structure that fits within a notch formed in the bottom exterior of the envelope. The frame and table are preferably collapsible to require minimum storage space when not deployed. If the victim is deceased, the enclosure can be undipped or otherwise released from the frame, and folded into a body bag containing all of the victims information and belongings and medical waste.
