Explosion Risk

A dynamic risk analysis model of offshore fire and explosion is proposed in this paper. It considers the effect of human and organizational factors in a more explicit way than current traditional risk analysis methods. This paper begins with exploring the recent advances on offshore fire and explosion risk analysis theories, followed by briefly introducing the research techniques employed in the proposed hybrid causal logic model which consists of event tree, fault tree, Bayesian network, and system dynamics. Thereafter, it proposes a quantitative risk analysis framework. At last, the applicability of this model to the offshore platform is also discussed. It aims to provide guideline for risk analysis of offshore fire and explosion.

Unsafe Behaviors

Hazardous chemical accidents (HCAs) seriously endanger public life, property, and health. Human and organizational factors are important causes of many kinds of accidents. In order to systematically explore the influencing factors of unsafe behaviors in HCAs in China, the method of human factors analysis and classification system based on the Bayesian network (BN-HFACs) was introduced. According to the 39 investigation reports of HCAs in China, the origin Bayesian network (BN) was obtained and the failure sensitivity of every node in BN was calculated. The results have shown that hazardous material environment (1.63) and mechanical equipment (0.49) in the level of preconditions of unsafe behavior have the same direction failure effect with operation error, while there is no factor has the same direction failure effect with operation violate. Some factors in organization influence and unsafe supervision, such as organization climate (0.34), operation guidance (0.37), planned operation (0.22), and legal supervision (0.19), are also important reasons for operational errors, while resource management (0.12), hidden investigation (0.18) and legal supervision (0.13) have an impact on operation violates. Moreover, there are still close relationships between other hierarchical elements, such as the operation guidance effect on the hazardous material environment (6.60), and the organizational climate has the most obvious impact on other factors at the level of organizational factors. Based on the above research conclusions, suggestions for individual, enterprise, and government were put forward, respectively, and the limitations of this study were also clarified.

This paper presents a risk management framework (RMF) for unmanned underwater vehicles (UUV). UUV are tethered or untethered vehicles operating in hazardous surroundings. The RMF, as one of the first for UUV, emphasizes the need for considering human and organizational factors impact on risk. A case study on risk assessment has been carried out, covering the risk of loss and mission abort of an autonomous underwater vehicle. It is based on a case study of the Applied Underwater Robotics Laboratory of NTNU, which operates several UUV. The assessment applies human reliability analysis, fault tree analysis, and event tree analysis. The case study identified measures for risk reduction, such as improvement and adaptation of procedures for maintenance, planning of missions, and fault recognition and solving.

Background: An objective, comprehensive and scientific evaluation of emergency medical rescue capability (EMRC) is of great realistic significance in assisting the health administrative department to grasp the overall response capability of all emergency medical rescue teams, enabling each team to have a full understanding of its own strengths and weakness and improve itself accordingly. At present, the research on the evaluation of EMRC in Hazardous Chemicals Accidents (HCA) is not systematic and in-depth, and the existing research results also have some shortcomings, such as, the lack of strong theoretical support for the evaluation index system, the relatively single function of evaluation methods, and so on. Objectives: The objective of this article is to research the evaluation index system and a new evaluation method of EMRC in HCA to overcome the above shortcomings. Methods: It establishes an emergency medical rescue capability model by employing the competency model and then constructs the evaluation index system on the basis of the analysis of all the factors of emergency medical rescue capability in hazardous chemical accidents and sets up an evaluation model based on the theory of connection numbers and partial connection numbers. It determines the competence ranking of several emergency medical rescue teams and the competence state of an individual emergency medical rescue team by calculating the connection principal value, and it also predicts how the emergency medical rescue capability will develop based on the values of partial connection numbers. Results: The example shows that the calculation process of this model is relatively simple, and its assessment results are objective and authentic, and moreover, its multi-functions can make up for the deficiency of the simplified function of other evaluation models. Conclusion: This method is scientific and rational to some extent and can provide reference for evaluation problems of the same kind.

Purpose The purpose of this paper is to appraise the Nigerian Economic and Financial Crimes Commission (EFCC) of their role in tackling systemic corruptions and to associate how institutional and organizational factors influence the performance of the EFCC. Design/methodology/approach Data were gathered through in-depth interviews, non-participatory observations and documentary analysis. Findings The results of the integrative analysis show that the EFCC has apparently been ineffective, and further improvization of the organization is needed. Poor performance of the EFCC was associated with factors such as lack of commitment, inefficient judiciary, insufficient budgets and incompetent personnel. Practical implications This study recommends further improvements in the form of a greater political will, improved legal process and also elevated budgetary funds and recruitment of personnel to the EFCC. Originality/value The study adopted a descriptive, qualitative case study approach to describe the current state of the EFCC in Nigeria.
