Appllcation And Stufy Of The Theory Of Safety System Engineering In Chemical Hazard Enterprises

This text makes safety measurement and forecast on system and correlating factors by exercising the methods of safety systems engineering. This text analyses the hazard factors which can arouse accident on equipment, implement, labor safety, industry circumstance, management of technique, management of basic information and safety management. The text analyses the fatalness of the above factors by determining the nature and quantitative analyzing, affirms the feasibility and the degree of severity of system's hazard, brings forward the necessary safe measures to keep away, achieves controlling accident ahead of schedule, reduces and perishes accidents, then makes the aim of"give priority to preventing"come true in word and deed.Base on the before investigation, this text analyses mechanism of accidents'damage which are very dangerous and often happen, sets up their model of damage, analyses by synthesizing several methods to determine the nature and fix quantify. It labors the efficient reason and complex system of accident in chemical plant, takes corresponding countermeasures and measures. It has strong applicability. Analysing, forecasting, controlling accidents, confirming hazard characteristic by calculational methods and setting up controlling measures can not only assure controling scheme bring into effect but also optimize the controling scheme.Apply different methods to discriminate and analyse by determining the nature and fixing quantify according production characteristic and typical fatalness in the chemical plant. Investigate the base of means to estimate dangerous chemical's fatalness and set up estimating mode. To the dangerous safety evaluation modes of chemicals put forward finally, the part of tin in some estimating item as the example. The estimating result are consistent with fact, the safety precautions put forward are in favor of finishing safety work to enterprise. Prove the rationality and feasibility of the estimating mode set up.It is very necessary and important to colligating manage safety estimating methods in chemical plant. Colligating manage estimating methods in chemical plant can discriminate latent hazards and deleterious factors, confirm the grade of hazards, bring forward safety countermeasures to prevent the hazards from developing to accidents. By forecasting it can reinforce more safety manage to correspond part, perform the duty of safe production and the system of safe manage strictly, reinforce safe establishment and safe technology so that it can assure equipment and establishment operating safely, and make the aim of producing safely come true.
