Improved Mond process used for safety evaluation

Abstract

The invention discloses an improved Mond process used for safety evaluation. The improved Mond process for safety evaluation includes steps of 1) acquiring safety information and identifying and classifying the acquired safety information, determining substitution events according to fault tree analyzing method, analyzing various reason events including basic events and non-basic events layer by layer and establishing a fault tree according to the analysis; 2) determining structure importance coefficient of each basic event and sequencing the structure importance of all the basic events from big to small; 3) determining 'suggest coefficient' range of the basic events by the Mond process during safety evaluation; and 4) determining value of 'adoption coefficient' within the given 'suggest coefficient' range, preferably taking high values of the large structure importance coefficients, and taking small values of the small structure importance coefficients. The purpose of realizing rationality of safety evaluation conclusion by means of science of safety evaluation is achieved, and actions on risk prediction and accident prevention from the safety evaluation can be effectively played.

Description

technical field [0001] The invention relates to a safety evaluation method, in particular to a method for improving the Mond method by determining the value of the "adoption coefficient" for safety evaluation using the Mond method by obtaining the structural importance of each basic event. Background technique [0002] With the rapid development of our country's industry, many production fields that were blank in the past are being filled continuously, and a large number of new products, new processes and new equipment are constantly emerging. Since the production of many newly built, rebuilt, and expanded industries is in a dangerous environment of fire, explosion, and poison, the issue of safe production is facing new challenges. In order to realize safe production and bring the safety production issue into the track of the rule of law, the safety evaluation of construction projects becomes an important measure that must be carried out. Therefore, the objective situation ...

Problems solved by technology

[0008] However, since the value of each risk coefficient of the Mond method is given in the given range of "suggested coefficient", the value of "adopted coefficient" determined by different evaluators may be very different, resulting in arbitrary safety evaluation. Therefore, different evaluators will have large differences in the evaluation results of the same production unit using the Mond method.
