Abstract
This paper reviewed the physical and chemical properties of chlorine and toxicological effects， Analysis of the chlorine production process and storage technology and its attention to matters， And chlorine production， stockpiling explosives in the process of risk were discussed， each of the reasons for the formation of dangerous source. The storage system in the cylinder of liquid chlorine leaked an analysis involving the storage of liquid chlorine cylinders need to set up the security of facilities， dealing with a leak summary. From the technology， equipment， instruments， and other aspects briefed chlorine leak， the explosion of chlorine system insecurity and preventive measures to ensure production safety. Focusing on the explosion of chlorine gas leakage. And various hazards to the preventive measures， introduction of a chlorine gas leak emergency handling of the chlorine leak and explosion accident in the man-made causes. Through the liquid chlorine production， storage and transportation of all sectors of the accident risk areas， raised the direction of risk prevention and emergency treatment and disposal of the basic principles.
