HAZOP Methodology Based on the Health, Safety, and Environment Engineering
International journal of environmental research and public health, 2020Co-Authors: Jae Young Choi, Sang Hoon ByeonAbstract:In existing Risk Analysis Techniques like the hazard and operability study (HAZOP) and the safety integrity level (SIL), design for operator safety is not considered. The health, safety, and environment (HSE) engineering depicts a detailed design directly related to the operator safety. However, the human Risk had not been comprehensively analyzed. This paper proposes HSE-HAZOP as a Technique for examining the systematic and efficient application of HSE engineering by exploiting the HAZOP systematic Risk Analysis Technique and a quantitative Risk derivation method, which is an advantage of the SIL. The Analysis consists of four steps: the HSE-HAZOP preparation phase, Risk Analysis phase, Risk assessment phase, and Risk reduction phase. One part of a solution styrene butadiene rubber (SSBR) plant was used for a case study. In this case study, the items that handle with heptanoic acid were the study scope. After the Risk assessment, we introduced the HSE engineering Technique that should be applied for the Risk reduction. Since there is no existing Risk Analysis method for HSE engineering, this proposed HSE-HAZOP is meaningful because it suggests systematic Analysis method of the operator safety.

A Framework Methodology for Selection of Risk Analysis Techniques in Construction Projects
2012Co-Authors: Alberto De Marco, Muhammad Jamaluddin Thaheem, Sabrina Grimaldi, Carlo RafeleAbstract:Project Risk Management has been gaining acceptance amongst the practitioners due to an untiring stress on its importance, and the availability of a number of Risk Analysis Techniques for facilitating this task in construction project management. In this arena, the selection of a suitable Risk Analysis Technique is critical to the entire project Risk management process and thus critical to the success of a construction project. However, the availability of an appropriate selection methodology, which may help the project managers choose a suitable methodology for their projects, seems missing. In this paper a selection framework methodology is presented, which looks at the realization of a practical tool that may help project managers and construction practitioners in choosing a suitable Risk Analysis Technique that satisfies select project drivers. Also, the presented work extends the traditional time, cost and quality drivers of a project by enhancing the focus to the level of complexity and maturity of the organization. The project drivers are further classified into four scales each, to assist in formulating a well-structured chart. The dimension of project Risk Analysis Technique is classified into qualitative, semi-quantitative, quantitative, and simulation scales, rendering a balanced diagram. Plotting the project drivers on the chart result in acquisition of the category of Risk Analysis Technique, which is appropriate under given variables. The paper further proposes individual classification of existing Techniques into the four categories of project Risk Analysis dimension, which may help practitioners to obtain a specific Technique for their construction project by conveniently putting in the variables into the proposed chart. Applicability of the framework methodology is finally presented followed by conclusions and future research directions

Model-based safety Analysis of human-robot interactions: The MIRAS walking assistance robot
2013 IEEE 13th International Conference on Rehabilitation Robotics (ICORR), 2013Co-Authors: Jérémie Guiochet, Quynh Anh Do Hoang, Mohamed Kaaniche, David PowellAbstract:Robotic systems have to cope with various execution environments while guaranteeing safety, and in particular when they interact with humans during rehabilitation tasks. These systems are often critical since their failure can lead to human injury or even death. However, such systems are difficult to validate due to their high complexity and the fact that they operate within complex, variable and uncertain environments (including users), in which it is difficult to foresee all possible system behaviors. Because of the complexity of human-robot interactions, rigorous and systematic approaches are needed to assist the developers in the identification of significant threats and the implementation of efficient protection mechanisms, and in the elaboration of a sound argumentation to justify the level of safety that can be achieved by the system. For threat identification, we propose a method called HAZOP-UML based on a Risk Analysis Technique adapted to system description models, focusing on human-robot interaction models. The output of this step is then injected in a structured safety argumentation using the GSN graphical notation. Those approaches have been successfully applied to the development of a walking assistant robot which is now in clinical validation.

Dam Risk Analysis and its appliation to Shaheji Dam
Hydro-Science and Engineering, 2004Co-Authors: Wang Ren-zhongAbstract:The dam Risk Analysis Technique established on the basis of the probability of dam failure and the estimation of loss of life and economic loss has been widely applied to dam Risk management abroad in recent years. The Risk Analysis of Shaheji Dam with this Technique is carried out, and the results show that the remediation of Shaheji Dam is necessary.
