a worst case methodology for obtaining a rough but rapid indication of the societal risk from a Major Accident Hazard installation
Journal of Hazardous Materials, 2002Co-Authors: I L Hirst, D A CarterAbstract:Abstract This paper describes a methodology developed to provide a rough but rapid indication of the magnitude of the societal risks at and in the vicinity of a Major Accident Hazard installation. It is intended to be used by the UK Health & Safety Executive (HSE) as a first screening tool when examining safety reports submitted under The Control of Major Accident Hazards (COMAH) Regulations 1999. These are the Regulations which implement in the UK the Major aspects of Council Directive 96/82/EC, the “Seveso II” Directive. Within the methodology a new weighted risk integral parameter is defined, suitable for comparison with criteria, and its value calculated. The paper includes examples to illustrate the use of the methodology.

a worst case methodology for risk assessment of Major Accident installations
Process Safety Progress, 2000Co-Authors: I L Hirst, D A CarterAbstract:This paper considers the application of one of the weighted risk indicators used by the Major Hazards Assessment Unit (MHAU) of the United Kingdom's Health & Safety Executive (HSE) in formulating advice to local planning authorities on the siting of new Major Accident Hazard installations. In such cases the initial consideration is to be assured that the proposed installation would not be incompatible with existing land uses in the vicinity, as determined by the categorization of the existing populations and the estimated levels of individual risk which the proposed installation would impose upon them. An analysis of the consequences and likelihood of a single “worst case” event, coupled with MHAU's “Risk Integral,” is then undertaken. This enables the societal risk aspects of the proposal to be considered at an early stage and, in many cases, allows a prompt response. The paper describes the methodology and includes several case studies based on MHAU's day to day work which illustrate its use.

worst case methodology for the initial assessment of societal risk from proposed Major Accident installations
Journal of Hazardous Materials, 2000Co-Authors: D A Carter, I L HirstAbstract:Abstract This paper considers the application of one of the weighted risk indicators used by the Major Hazards Assessment Unit (MHAU) of the Health and Safety Executive (HSE) in formulating advice to local planning authorities on the siting of new Major Accident Hazard installations. In such cases the primary consideration is to ensure that the proposed installation would not be incompatible with existing developments in the vicinity, as identified by the categorisation of the existing developments and the estimation of individual risk values at those developments. In addition a simple methodology, described here, based on MHAU's “Risk Integral” and a single “worst case” even analysis, is used to enable the societal risk aspects of the Hazardous installation to be considered at an early stage of the proposal, and to determine the degree of analysis that will be necessary to enable HSE to give appropriate advice.

Multi-target Inherent Safety Indices for the Early Design of Offshore Oil&Gas Facilities
Process Safety and Environmental Protection, 2020Co-Authors: Anna Crivellari, Sarah Bonvicini, Alessandro Tugnoli, Valerio CozzaniAbstract:Abstract Improved tools are needed to manage Major Accident Hazard of progressively more complex offshore oil&gas systems in environmentally sensitive areas. Inherent safety principles provide a strategic opportunity to reduce Major Accident Hazards since the early design phase, but a suitable metric to orient safer design choices is needed to apply such principles intro practice. This study aims at providing a systematic approach to the assessment of the Hazard profile of alternative process designs in offshore oil & gas production facilities. A novel methodology providing a ranking of inherently safer solutions in conceptual design is described. The methodology is able to highlight the different contributors to the safety profile of the offshore oil & gas production system, linking them to the specific features of the design. The proposed approach, based on multi-criteria Key Performance Indicators (KPIs), addresses different targets (people, assets, environment) and provides a quantitative assessment of the safety score, accounting for both the possible Accident consequences and their credibility. An application to a case study concerning an offshore facility for gas production is discussed to demonstrate the potential of the methodology.

Major Accident Hazard in biodiesel production processes
Safety Science, 2019Co-Authors: Valeria Casson Moreno, Enrico Danzi, Luca Marmo, Ernesto Salzano, Valerio CozzaniAbstract:Abstract The number of biodiesel production plants is rapidly growing around the world, and the related “green” technologies are developing to full industrial scale within a brief time. The exploitation of these relatively new technologies with a low operational experience is however leading to an increase in the number of Accidents in this industrial sector. To better address and characterise the problem of the high Accident rate in the “green” technologies in biodiesel production, an in-depth statistical analysis of past Accidents has been performed. The set of records analysed (93 events, from 2003 to 2017) has been selected to depict the most relevant factors affecting the Accident rate, e.g. the age of the plant and its status at the time of the Accident or unit and substances involved. Correlations between characteristics of the unwanted events, such as scenario and causes, have been evidenced. The analysis of the frequency and severity of past Accidents allowed an estimate of the risk figure with respect to Major Accident Hazard for biodiesel industry, unveiling the misconception for which green technologies as biodiesel production are often perceived as safer.

Major Accident Hazard in bioenergy production
Journal of Loss Prevention in The Process Industries, 2015Co-Authors: Valeria Casson Moreno, Valerio CozzaniAbstract:Abstract Some recent Accidents involving the bioenergy production and feedstock supply chain raised concern on the safety of such technologies. A survey of Major Accidents related to the production of bioenergy (intended as biomass, bioliquids/biofuels and biogas) was carried out, and a data repository was built, based on past Accident reports available in the open literature and in specific databases. Data analysis shows that Major Accidents are increasing in recent years and their number is growing faster than bioenergy production. The results obtained represent an early warning concerning the Major Accident Hazard of bioenergies, and suggest the importance of risk awareness and safety culture in bioenergy production, in the perspective of a safe and sustainable exploitation of renewable resources.

quantitative assessment of environmental risk due to Accidental spills from onshore pipelines
Process Safety and Environmental Protection, 2015Co-Authors: Sarah Bonvicini, Giacomo Antonioni, P Morra, Valerio CozzaniAbstract:Abstract The transport of Hazardous materials by pipeline is widely used for the transfer of significant quantities of oil and chemicals. Due to the extremely low frequency of spills, pipelines are considered the safest mode for the land transportation of Hazardous substances. Accident records, while confirming that Loss of Containment (LOC) events are rare, also point out the Major-Accident Hazard of pipelines, due to the extremely severe potential consequences of spills. Quantitative Risk Analysis (QRA) techniques have been applied to pipelines since many years with the aim of evaluating risk for workers or exposed population. However, releases of liquids, as oil and oil products, also create an Hazard to the environment, due to the potential of extensive soil and groundwater contamination. An integrated model was developed for the environmental Risk Analysis of spills from pipelines. Specific environmental risk indexes were defined, expressing the risk of soil and groundwater contamination, both in physical and economic terms. A case-study is presented and discussed to illustrate the features of the methodology. The results confirmed that the proposed model may be considered an important tool within a comprehensive approach to the management of risk related to onshore pipelines.

impacts framework for risk assessment of co2 transport and storage infrastructure
Energy Procedia, 2017Co-Authors: A. Brown, Charles Eickhoff, J E A Reinders, I Raben, M P N Spruijt, Filip NeeleAbstract:Abstract There is an urgent drive to implement Carbon Capture and Storage (CCS) on a commercial and global scale. This needs to be done in a demonstrably safe and responsible manner that gains widespread acceptance of stakeholders, most notably regulators and the public. If inhaled in sufficiently high concentrations, CO 2 can have toxicological effects on the human body. The Hazardous aspects of CO 2 , combined with the very large quantities that will be contained within CCS systems create the potential that a leak from a CO 2 system could pose a Major Accident Hazard. The CO 2 stream from capture plants will not be 100% pure, but contain substances, referred to as stream impurities, such as CO, H 2 O, H 2 S, NOx, SOx, O 2 and H 2 that, although in very low levels, can change the properties of the CO 2 stream and can change the likelihood and/or the consequences of CO 2 system leaks. The IMPACTS project is concerned with the impact these impurities may have when present in CO 2 transport and storage systems. The risks associated with CO 2 captured as a result of CCS operations differ from those previously encountered either in Natural Gas pipelines or in pure CO 2 pipelines (used in USA and elsewhere for enhanced oil recovery operations) in a number of ways, but particularly on account of the large volumes, high pressures and nature of the impurities involved. Established techniques can be used to determine the risks from events that would undermine the overall integrity derived from the design, manufacture, construction and operation of the infrastructure. Some of these techniques and the assessment thereof have been described, together with consequences that can be expected, based on industry experience with pipelines other than those transporting impure CO 2 . Some of the event types that can lead to a reduction in the level of safety of transport and storage of large volumes of impure CO 2 , under high pressure, have been identified, and the associated risks described. A significant amount of information, including guidelines, industry standards and legislation, exists worldwide and provides decision support for the design of pipelines carrying Hazardous materials. This includes risk reduction measures, requirements for risk assessment, risk criteria and the need for further risk reduction. However, in most cases CO 2 is not currently in the scope, but it is possible to apply many of the principles therein to pipelines containing CO 2 , albeit with some caution. In the absence of agreed guidance figures, reference is made to standards that could be used in system design to support a Safety Case to demonstrate that the risks are at an acceptable level. It would be hoped that these will serve to stimulate debate and provide a starting point from which an acceptable balance might be found between applying additional measures to improve safety by design, and providing projects that are affordable, at the same time allaying public concerns implicit in the introduction of new technologies. At the same time an ISO Standard for CCS is being produced, and this also attempts to provide necessary guidance for system designers.

The sub-elements are prepared such as to reflect the availability of the safety and security management system in industries. Results: Major Accident Hazard industries require more attention towards safety and security management systems. The safety management system has gained more prevalence than security management system in large scale industries than the medium and small scale industries. The safety management system has considerable prevalence than security management system in medium scale industries than the small scale industries. The safety and security management system have more or less the same prevalence in the small scale industries. Conclusion: All the industries should devise systems for the adoption and implementation of safety and security management system. Security failures can lead to safety failures and hence they must be given equal importance. The Major Accident Hazard industries should adopt all the safety and security management elements. All the elements of safety and security management systems should be given equal importance for effective and safe functioning of the industries. The security management system is an upcoming field which needs to be sincerely implemented in the industries in the present scenario of global terrorism. The safety and security management system should go together in a coherent manner to reduce the societal risk.
