ABSTRACT:
A safety chute for enabling people to escape from a building during an emergency which consists of a tube, a water tank located at the bottom of the tube, and a parachute inside the tube for controlling the velocity of the descending person. By raising the water level above the tube exit, air is trapped between the water and the parachute, thereby providing the upward pressure on the parachute during the descent.
