Method for recognizing and evaluating major safety risk of metal smelting enterprise

Abstract

The invention discloses a major safety risk recognition and evaluation method for a metal smelting enterprise. The method comprises the following steps: collecting accident case data of a metal smelting enterprise, analyzing accident cases, and searching risk factors related to accidents; dividing risk units according to a metal smelting process, and compiling a metal smelting enterprise general risk recognition list; forming a general risk and hidden danger violation evidence information list; dividing risk evaluation units by taking the smelting process as a unit and taking the risk point as an evaluation main line; establishing a metal smelting enterprise high-risk inherent risk index system, and calculating an inherent risk index of a risk point through the established metal smelting enterprise evaluation model; unit inherent risk evaluation, unit risk frequency determination, unit initial high-risk safety risk evaluation and dynamic risk factor recognition; the unit risk is aggregated to the enterprise risk. The intrinsic safety degree and the safety management level of metal smelting enterprises are improved, major and extra-major accidents are prevented, and accident harm consequences are relieved.

Description

technical field [0001] The invention belongs to the technical field of enterprise safety risk identification and evaluation, and specifically relates to a method for identification and evaluation of major safety risks in metal smelting enterprises. Background technique [0002] The metallurgical industry risk identification and assessment technology is accompanied by the development of the theory of safety system engineering. By digesting and absorbing foreign safety checklists and safety risks, relevant enterprises in machinery, metallurgy, aerospace, aviation and other industries began to apply risk analysis and evaluation methods, such as safety checklist (SCL), fault tree analysis (FTA), fault type And Impact Analysis (FEMA), Preliminary Hazard Analysis (PHA), Hazard and Operability Study (HAZOP), Hazard Evaluation of Operating Conditions (LEC), etc. [0003] The "Inflammable, Explosive, and Toxic Major Hazard Identification and Evaluation Technology Research" project c...

AI Technical Summary

Problems solved by technology

[0010] The production chain of metallurgical enterprises is long and complex, involving high-temperature molten metal, flammable, explosive, toxic and harmful gases, high-energy and high-pressure equipment, dangerous mines and tailings ponds, etc., which are likely to cause safety production accidents

[0011] The major accidents in China in recent years show that the industry-focused management approach to prevent major accidents can no longer adapt to the current safety production reality. How to establish a set of accurate, forward-looking, systematic and comprehensive policies for The prevention and control system is a major issue that needs to be solved urgently
