ABSTRACT:
A fire escape apparatus comprises a vertically extending channel member defining a channel into which opens a slot formed between flanges constituting a front wall of the channel member. Rows of staggered projections within the channel are formed by bolts extending between the flanges and a rear wall of the channel member. A harness for supporting a person escaping in the event of fire or other emergency is suspended from a T-shaped support including a cross-piece, and an upright. In use, the cross-piece and upright are introduced into the channel through the slot. A lug on the upright projects through the slot and limits side-to-side movement as the harness support descends under the weight of the person escaping, the cross-piece co-operating with the bolts to perform a stepping movement.
