The Escape Rescue System is a building-wide solution for safe, external evacuation of building tenants and the rapid transport of rescue personnel to the upper reaches of a skyscraper. The system is composed of at least two devices; each is an array of five collapsible cabins. The system is permanently stored on the roof in a folded position. Upon activation by first responders, each array is lowered to the ground.
