Quantitative risk assessment of the Italian gas distribution network

European Critical Infrastructures include physical resources, services, information technology facilities, networks and infrastructure assets, which, if disrupted or destroyed would have a serious impact on the health, safety, security, economic or social well-being of the Member States.The gas distribution network is a critical infrastructure and its failure can cause damage to structures and injury to people.The aim of this paper is to analyze and then assess the risk of the Italian high pressure natural gas distribution network.The paper describes an application of a methodology for quantitative risk assessment.Failure frequencies considered in risk calculation were found in the European Gas pipeline Incident data Group (EGIG) database, whereas consequences were computed as a function of pipe diameter and operating pressure for each section of the network. The results of this quantitative risk assessment is the determination of local and social risks for the Italian North East Area.     

Investigation of stakeholders' awareness and adoption of Inherently Safer Design (ISD) principles in South African utility industry projects

The paper examines the level of awareness of stakeholders in adopting Inherently Safer Design (ISD) principles in the Project Life Cycle Management (PLCM) of South African Energy utility projects. It seeks to understand whether stakeholders in the latter stages of the Project Life Cycle are competent to make design change decisions on these projects. ISD principles are essentially useful for reducing risks and as such, safety experts have acknowledged it as an excellent approach in the design process. However, there are no known efforts to date that attempt to integrate ISD concepts into PLCM. This paper seeks to fill this gap. This study, through the review of extant literature establishes that ISD principles can be used in project procurement, and adopts a quantitative survey approach in obtaining information from stakeholders in the South African utility industry. Findings reveal that the principles of inherent safety are permeating into the management of South African utility projects but the level of awareness and its adoption are below optimal levels. It also emerged that there is a divergent awareness of ISD strategies amongst PLCM stakeholders and that the design engineers are better informed about the ISD approach of eliminating risks and hazards in the industrial systems studied than other stakeholders. The findings also indicate that the level of awareness of stakeholders of ISD principles is greater within earlier project phases. Based on these findings, the paper concludes that the hazards witnessed within the project execution and finalization phases could be as a result of the low levels of awareness, divergent views and lower use of ISD strategies by PLCM stakeholders. It is suggested that the level of awareness of the principles, concepts, basics and benefits of integrating ISD into PLCM be raised amongst stakeholders functioning within utility industry project procurement in South Africa and that design changes be limited to the earlier phases of utility project procurement.

Optimal feed profile for a second order reaction in a semi-batch reactor under safety constraints: Experimental study

Maximising the yield of the second order reaction (2-butanol+propionic anhydride) by manipulating the inlet flow rate is considered for an isothermal semi-batch process. First a procedure for the determination of the kinetic parameters using coupled spectroscopic and calorimetric methods is presented. Then an optimisation of the reaction system is performed numerically and verified experimentally. Constraints on the amount of heat produced and on the temperature attainable in the case of cooling failure are imposed for safety consideration.     

我国部分保健与安全活动经济代价的初步评价

社会中的许多卫生保健活动都需要在经济代价和人的安全健康之间作出权衡。这种权衡往往需要确定危害人们健康和安全的经济价值。笔者从人力资本和支付意愿两个方面,对我国卫生、环保、安全有关的经济数据进行了评价分析。在人力资本方面,考虑了人均终生的国民生产总值、国民收入、消费水平、职工工资、城乡居民收入。在支付意愿方面,考虑了医疗救治的费用、社会保险费用、司法赔偿、职业劳动保护费用、降低辐射危害的费用以及政府采用数值等。根据这些分析评价,笔者建议：我国卫生保健有关的人的社会经济价值,若以１９９０ 年可比价格计算,分布在（９～４０）万元之间,适中的估计为２０ 万元。
