Abstract
A grill is attached over an opening in a building. The top of the grill, which is connected together by a cross member, is securely attached to the side of the building. The lowermost portion of the grill, which is also connected by a cross member, pivots about the upper or a central cross member. The lower portion of the grill is held over the opening and against the side of the building by a quick release locking mechanism operated from inside the building. Upon release of the quick release locking mechanism, the lower portion of the grill will be allowed to swing outward so that a person may leave the building through the opening in case of an emergency.
