Accessible Means of Escape Design: This egress design is a unique and integral part of the enhanced staircase development of vertical exits in tall building. It requires the ability of incorporating the facility of multiple escape chute system inside the enhanced staircase enclosure. When fire occurs, the disabled and the severe mobility impaired will have to make their way, assist or unassisted, and take temporary refuge inside this stair enclosure that would get them to the ground floor more quickly and relatively safely or to be assisted by helpers down the stairs.
