Practicable research on job safety analysis format in construction project area

Hazard identification and risk assessment are the basic elements of risk management.The general techniques include Safety Checklist,Hazard and Operability Analysis,Failure Model and Effects Analysis,Fault Tree Analysis,Event Tree Analysis etc.The aim for hazard identification and risk assessment is to analyze the reliability of work system,includes analyzing the reliability of system elements and the coordination between the system elements.We used to analyze the coordination between system elements by Safety Checklist technology which is considered not applicable,because there are a number of variable factors which infect the coordination.However Job Safety Analysis technology is a scientific technology to analyze the coordination between system elements intensively.In this thesis the theory of Job Analysis and Assessment element was introduced,together with the latest research results from the occupational health and safety theory,the traditional Three Processes theory was improved,and the standard Four Processes theory was put forward.At the same time,the practices of JSA Model in construction project area were studied.
