METHOD AND APPARATUS FOR PROVIDING REFUGE PASSAGEWAYS
A system and method for providing safe passageways in refuge walls such that the completed apparatus limits the infiltration of noxious and/or hazardous gasses in the atmosphere external to the refuge from entering the refuge during personnel ingress or egress, in which entry and exit can be accomplished without contaminating the refuge environment by way of flexible, conforming, rubber like sheeting, partially overlapped in single or multiple layers of varying directions, that will conform to occupants as they enter or leave the refuge or shelter.
