FIELD: survival aids. SUBSTANCE: arrangement for escape from multistory buildings makes it possible to quickly lower the dwellers from the roof to the ground.

The next dweller to be rescued is connected to a ring, it is shifted behind the fork to the building roof and lowering is accomplished. Rescuers adjust the lowering deceleration force by setting apart the ropes. EFFECT: enhanced reliability. 2 cl, 3 dwg
