Study On Work Safety Process Of Construction Companies Based On Dangerous Point Analysis

Work safety is one of targets that construction companies pursue in their operating process. Some construction enterprises take actions in variety to control and keep them from safety accidents, and work safety process consists of systematic work steps. Work safety process is an important part of overall work process of construction companies which marks safety accident controlling level and work safety capability. Therefore, further research on work safety process has theoretical sense as well as practical value.There have not been any theories of work safety process discussed systematically till now. Work safety process aims to control and keep contruction companies from safety accidents. The existing approaches are effective and to point only when they are considered from a particular respective. However, in nature, there is no efficient systematic innovative continous work safety process. This paper conducts the following research based on the above, in hope that it may offer a new theorical framework and approach of work safety process in future.Contruction companies structure work safety process based on safety accident mechanism. From dangerous point respective, the studay focuses on constitution of insecure factor collection and the relevance to reveal nature of safety accident and Safety Rheology process in combination with the character of construction company and the regulars of safety accident.In view of the subject involved in work safety process, the systematic research on constitution of safety accident and safety problems is carried out. Based on fault tree analysis, the paper puts forth coupling fault tree theory in the field of system safety project, and constructs the structural model of safety accident and normal operating structural model. The systematic approach to measure safety risk is given here. In addition, further study on the indicators and the sequence of structural importance and probability importance as well as cirtical importance, which may the guide that the construction companies will follow in field of work safety.
