A building evacuation system in which at least one vertical evacuation chute is provided for each floor of a building to be evacuated. A plurality of collapsible buckets are stored on each floor and, after loading, are slid along horizontal rails to the vertical chute where they engage a plurality of vertical guide tracks. The guide tracks are provided with tapered brake pads so as to provide progressively increasing braking force on the falling buckets. A sloping slide is provided adjacent a lower open end of the chute to slidably transfer the bucket and evacuee to the ground.
