Factors influencing the implementation of a safety management system for construction sites

The objective of the study was to determine the influential safety factors that governed the success of a safety management system for construction sites. The number of incidences among construction workers and the level of awareness on matters concerning safety were also determined. The study involved a self-administered three-part questionnaire among the workers and interviews with industry experts involved in brick-laying, concreting and in related assorted trades. Part A of the questionnaire concerned personal particulars, Part B involved training and experience and Part C was based on 28 industry-accepted safety factor elements. The construction sites ranged from high rise buildings, landed houses and infrastructure renovation. The sample size was 275. From the survey it was found that the most influential safety factor was personal awareness followed closely by communication. Suggestions and recommendations on equipment design and improved work practices and procedures to improve the efficiency and productivity of construction workers were proposed. Management was urged to get their workers better informed about safety matters.     

Building urban gas process safety management (UG-PSM) system: Based on root cause analysis with 160 urban gas accidents in China

Urban safety is significantly impacted by the complexity of urban gas accidents. Although China has put forward the goal of “zero fatalities in accidents” for urban gas, unfortunately, the root causes of the unsound safety culture and imperfect safety management system of urban gas enterprises remain unresolved. Therefore, statistical analysis and 24Model analysis of 160 urban gas accidents in mainland China were performed to investigate the proximate causes of the accidents and the current situation of urban gas safety. The CCPS's risk-based process safety elements were used to identify potential deficiencies in the current urban gas process safety management (UG-PSM). During the analysis, it was observed that insufficient implementation of concealed danger investigation and rectification accounted for 76%, which is the primary proximate cause of urban gas accidents. Stakeholder outreach is the most under-represented competency in urban gas safety management. Based on the results, a novel framework for the UG-PSM system was constructed, and the theory of urban gas safety management was further improved. Furthermore, we evaluated the matching degree between UG-PSM elements and the existing measures of the government, urban gas associations, third-party organizations, and urban gas enterprises. Finally, we analyzed the feasibility, challenges, and development directions of the UG-PSM system. This study establishes a foundation for researchers and practitioners in the future research and practice of urban gas process safety and provides theoretical guidance for preventing high-incidence accidents of urban gas in China.

Backtracking and prospect on LNG supply chain safety

The safety issues of Liquefied Natural Gas (LNG) in production, storage, loading/unloading, transportation/shipping, and re-gasification have became a major concern, since an accident in the LNG industry would be very costly. Understanding the threat of LNG not only contributes to the process safety and reliability in the research and development (R&D) system, but improves the efficiency of loss prevention, fire protection and emergency responses. As of April 2019, in order to obtain the present status and trend of LNG safety research, basing 1122 documents of the Web of Science database about safety research of LNG as a data source, CiteSpace and VOS viewer were used for network knowledge map analysis. A comprehensive knowledge map of LNG safety field was obtained from several research aspects including scientific research power, research hot spots and trends, research knowledge base and frontier. According to the study results, the development of LNG safety research was divided into four stages from 1970s to 2019, China and South Korea made a lot of contributions, and the United States is the most influential. Among them, the research from 2005 to 2019 was the most representative. Current research results indicate that a combination of Formal Safety Assessment (FSA) methodology and Dynamic Procedure for Atypical Scenarios Identification (DyPASI) will fully identify risks; The PHAST and TerEx programs quickly define safety zones. Computational Fluid Dynamics (CFD) software package can provide accurate quantitative data for the study of LNG safety. Research on quantitative risk assessment (QRA) and LNG evaporated gas (BOG) has been a hot topic and trend in this field. The application of expansion foam in LNG accident mitigation covers most of the research content in this field, and the optimization of LNG liquefaction process has a great influence on this industry. As the international demand for LNG energy output increases, floating liquefied natural gas (FLNG) will have considerable development, and increasingly researchers attach vital importance to the safety of LNG offshore production integrated unit.

An airport occupational health and safety management system from the OHSAS 18001 perspective

Occupational health and safety represents a set of technical, medical, legal, psychological, pedagogical and other measures with the aim to detect and eliminate hazards that threaten the lives and health of employees. These measures should be applied in a systematic way. Therefore, the aim of this study is to review occupational health and safety legislation in Serbia and the requirements that airports should fulfill for Occupational Health and Safety Assessment Series certification. Analyzing the specificity of airport activities and injuries as their outcomes, the article also proposes preventive measures for the health and safety of employees. Furthermore, the airport activities which are the most important from the standpoint of risks are defined, as the goals for occupational health and safety performance improvement.     

油气管道本质安全影响因素分析及启示

管道运输是油气运输的主要方式,为了研究油气管道本质安全的影响因素和薄弱环节,通过分析美国和加拿大油气管道的事故原因,识别了3种影响因素和7个薄弱环节;通过统计管道工程各阶段的事故和影响因素的数量,分析了每个阶段存在的本质安全问题。结果表明:施工阶段的事故和影响因素的数量远多于其他阶段;施工和制管阶段的影响因素种类多,事故原因分散,本质安全提升难度较大;设计和运营阶段的影响因素种类少,事故原因相对集中,本质安全提升难度相对不大;各阶段都存在技术和管理的不足。根据油气管道本质安全影响因素分析结果,得出管道本质安全5个方面的启示。
