  • Publication number: 20130048426
    Abstract: A rescue device for assisting in removing an individual from a particulate collapsed space comprising rectangular sheets having four sides with one longitudinal side having a male connector and the other longitudinal side having female connector. The sheets fit together by the female connector on one sheet sliding over the male connector on another sheet. The sheets can be individually inserted into the particulate, connecting one sheet at a time, this making it easier to create a rescue cavity. The sheets connect and are adapted to curl around so as to selectively create a rescue cavity of a desired size.
