The vent pipe of the emergency discharge collection tank of the emulsion polymerization reactor lacks a flame arrester and is inconsistent with the design drawings； 17. Failure to establish a regular dust cleaning management system ； 18. The terminator tank lacks a level gauge. ； 19. The "Safety Assessment Report of Jiangsu Corning Chemical Co., Ltd." compiled by Jiangsu Taijie Zhibang Testing Technology Co., Ltd. in March 2016 states that the medium-pressure delivery polymerization kettle reaction terminator is equipped with a standing nitrogen cylinder, and the polymerization kettle pressure is actually used for pressure delivery. The evaluation report is inconsistent with the actual situation.

Only such inspection and guidance can help enterprises make progress
