Study on Necessity and Safety Measures of Elevator Evacuation during High-Rise Building Fire

Elevators are increasingly widely used in high-rise buildings. Because of its fast running, elevators, with great potential value and social requirements, are now days becoming very important traffic tools in high-rise buildings. However, it is an urgent problem to evacuate safely by using elevators during high-rise building fire accidents. This paper elaborates the necessity of elevator evacuation, analyzed the problem of evacuation by general passenger elevators. Some useful measures are put forward, such as fire prevention, smoke-proof, water-proof and emergency power supply for elevator evacuation during high-rise building fires. It is of great importance for us to utilize these measures for the evacuation by elevators during high-rise building fire accidents.
