Risk assessment and countermeasures research of Shanghai chemical industry supply and marketing co., LTD.,about a storage warehouse

Abstract: study on a dangerous chemical products storage aspects of the Shanghai chemical industry supply and marketing co., LTD., use of safety evaluation theory knowledge, from the material risk accident type and enterprise two aspects of the enterprise is dangerous and harmful factors identification, identification of major hazards. Through the identification of dangerous and harmful factors, select the MES evaluation getting legal analysis of the three parameters related to the accident risk, calculate the accident risk value; Adopted the dow chemical fire and explosion danger index assessment method of the comprehensive analysis of the storage tank area # 2 and # 4 tank farm storage technological process and equipment characteristics, the terminal unit has great fire and explosion danger, take corresponding safety measures, obtained the effective risk control; Selected the pool fire evaluation method, through the establishment of mathematical model, simulation of accident consequences, the xylene formation of pool fire is obtained after the influence scope; Select the fault tree analysis, deduce the approach of dangerous chemical poisoning accidents, find out the control measures of the accident. According to the current relevant laws and regulations and enterprise storage process characteristics, aiming at security problems appeared in the process of evaluation, prevention and improvement measures are presented.
