Multi-factor combination risk identification method in construction safety risk control system

Abstract

The invention discloses a multi-factor combination risk identification method in a construction safety risk control system, and the method comprises the steps: collecting construction safety risk factors, building a risk factor database, and building the construction safety risk control system based on the risk factor database. Historical construction safety accident events are summarized and recorded into a construction safety risk control system, and the construction safety risk control system compares risk factor data; grading the danger degree and the occurrence possibility of the risk accident; more comprehensive and accurate risk factors are obtained by collecting construction safety risk factors and summarizing historical construction safety accident events, the danger degree and the occurrence possibility of risk accidents are graded, a risk analysis model system is established, more accurate risk factors are obtained, and the risk analysis efficiency is improved. According to the method, a plurality of construction safety risk factors are comprehensively analyzed to obtain more comprehensive risk factors, a risk early warning level is set, risk management training is enhanced according to the risk early warning level, and precautions are taken in the bud.

Description

technical field [0001] The invention relates to the field of project construction safety, in particular to a multi-factor combination risk identification method in a construction safety risk control system. Background technique [0002] The identification of accident hazards on project sites is an important issue in construction. A large number of close work tasks, unpredictable and uncontrolled activities have increased the accident rate on project sites. Compared with other industries, the construction industry has the highest accident rate, especially falls, collisions and mechanical accidents, so it is necessary to install fences, barriers and guardrails around dangerous areas such as elevator shafts, floor openings, excavation areas, trenches and mechanical work areas. Safety measures to reduce the accident rate. [0003] In order to improve the safety of the project site, some studies have proposed a formula for calculating the safety risk level, which can calculate t...
