Abstract
A collapsible bag assembly is described which provides a barrier for protecting an appliance item against flood water damage. The bag assembly includes a) a water impermeable flexible tube of plastic sheeting which is open at the top and closed at the bottom and b) a platform base attached to the bottom of the tube. The bag assembly is used by positioning the appliance item on the platform base. During passive periods, the bag assembly is in its collapsed position whereby the tube of plastic sheeting is folded and stored along the edge of the platform base in proximity to the lower part of the appliance item. When it is necessary to protect the appliance item against water contact, the bag assembly is deployed to its extended position by lifting the tube of plastic sheeting from its stored position and extending it toward the top of the appliance item where it is secured until such protection is no longer required.
