【 摘 要 】

The main hazards of the isopentane-isoprene charge cooling unit of isoprene rubber production are analyzed. The conditions for the emergence and development of emergency situations were studied, and existing measures to ensure safety at work were considered. The main initiating event in case of emergency situation in the shop is depressurization of equipment accompanied by the release of significant amount of hazardous substance with subsequent negative development of the accident. Activities aimed at reducing the risk of an accident at the facility are: reducing the probability of depressurization of equipment; minimizing the quantity of hazardous substances entering the accident site; localization of the accident site; limiting the time spent in hazardous areas. It is proposed to equip pipelines at the site boundaries with high-speed shut-off valves with a response time of 12 seconds. This measure allows minimizing the quantity of hazardous substances entering the accident sitethat leads to a significant reduction of environmental and economic damage because of accident.
