摘要：近年来，随着经济的蓬勃发展，作为基础工业的化学工业在迅猛的发展，化工企业的数量也在与日俱增。化学品的生产在促进经济发展和改善人们生活质量的同时，也带来了不可忽视的安全问题。化工生产过程中的原料、半成品、副产品、产品及废弃物常都具有危险性，往往伴随着易燃易爆、有毒有害、腐蚀等危害，极易造成大面积伤亡的事故。因此，现阶段对化工企业的危险源进行综合评价具有重要的现实意义。35929

Assessment of the safety status of the use and storage of toxic products of a company
Abstract: In recent years, with the economy booming, the chemical industry as a basis industry was developing rapidly. The numbers of chemical companies were also increasing. The production of chemicals were not only promoting economic development and improving the life quality, but also brought security problems which could not be ignored. The raw materials, semi-finished products, byproducts, waste products in Chemical production process often had a dangerous. It often accompanied with explosive, toxic, corrosive and other hazards. It could easily result in large casualties. Therefore, at this stage carrying out a comprehensive evaluation in the source of the danger of chemical companies had important practical significance.
Through analysis on existing research results at home and abroad and of a chemical companies in the field of research, the use of a chemical enterprise toxic chemicals storage safety analysis and chemical enterprises of dangerous source of comprehensive evaluation index system and evaluation of comprehensive security analysis method was studied, to guide chemical enterprises of dangerous source monitoring and accident prevention, to reduce the accident rate, reduce the loss and achieve optimal security investment efficiency has important significance.
