Towards a new approach for the identification of atypical accident scenarios

Proper hazard identification (HAZID) in safety reports has become progressively more difficult to achieve. Several major accidents in Europe in recent years, such as Buncefield and Toulouse, were not even considered by their site ‘Seveso-II’ Safety Case. One of the reasons is that available HAZID methodologies take no notice of apparently least likely events. Nonidentified scenarios thus constitute a latent risk, whose management is extremely complex and open ended. For this reason, the EC project iNTeg-Risk, in one of its tasks, aimed to investigate the issue of atypical scenarios and explain how they could have been identified. This study wants to describe the approach used and its immediate results, paving the way towards a new method for the identification of atypical accident scenarios. An in-depth accident analysis of some of these accidents was performed, in order to outline general features of plants in which they occurred, their causes, consequences, and lessons learned. This analysis followed a precise common scheme, which allowed a systematic approach to the problem by the experts involved. Based on the findings, failures connected to risk management and risk appraisal were identified. Three main basic issues in risk appraisal were identified: the low perception of emerging risks related to atypical accident scenarios, the lack of knowledge about related events, such as early warnings, and the incapability of current techniques in leading analysts to the identification of atypical scenarios.     

A Review of Catastrophic Risks for Life Insurers

Catastrophic mortality events are characterized by a sudden and concentrated increase in mortality and as such present a major risk to life insurers. Such events include pandemics, war, natural disasters, terrorist attacks, and industrial, transport, and other accidents. Of these, pandemics arising from influenza are considered the most significant threat to the life insurance industry due to their capacity to cause a major increase in claims. We review the features and mortality implications of an influenza pandemic for life insurers, and describe a range of other risks that are likely to emerge as well.     

Organisational risk perception and transformations in India’s nuclear establishment

The discourse on nuclear power and risk has shifted over the last few decades from security concerns emanating from nuclear weapons to threats to public safety in the event of industrial nuclear accidents. While the main focus of existing scholarship has been on public risk perceptions, comparatively little is known about organisational risk perceptions and the factors that influence organisations’ willingness to accept the incalculable risks of nuclear power. This paper provides insights into how the nuclear establishment in India thinks about risk. Drawing on interviews with the senior management of nuclear organisations, the analysis shows that organisational risk perception is not merely a human construct or the outcome of simple technical cost-benefit rationalities. It is the result of interactions between material and ideational conditions of risk. These conditions are expressed through three core organisational narratives: (1) the growth imperative, (2) technological nationalism and (3) faith in systems and technology. While there is generally a strong consensus on these narratives within and among the nuclear organisations in India, the data also show that organisations are not homogenous entities. Instances of self-critique and reflexivity exist which could open new spaces for change towards a more inclusive organisational discourse on nuclear risk in India.     

Risk management; a behavioural perspective

The risk contributor is usually regarded as responsible for risk mitigation and accident compensation, especially when the risk is due to the operation of a commercial company. The culpability of risk has resulted in several approaches to safety management. Risk management based on quantitative risk analysis (QRA) emerged in the defence and nuclear industry during and after Second World War and is by now introduced in almost every industry with high-risk potential. During this period, risk analysis and management as a profession has evolved considerably. Technical failures and operator errors used to be considered as the prime causes of accidents in the early days of risk analysis. Based on investigations of major accidents in the latter half of the last century, poor safety culture and mismanagement were introduced as possible additional causes of major accidents. Human error in decision-making is, however, rarely quantified and thus not included in QRA. Knowledge from the experimental analysis of behaviour is absent in practical or operational risk management. This paper advocates an approach to risk management where the decision part of the chain of events is explicitly included. The behavioural perspective introduced implies that the application of experimentally based behaviour science and QRA both should be pursued, mainly because QRA is a strong, and probably the best, defence against decision errors. In an operational situation, management must do trade-offs between objectives where safety is but one of several considerations. When the risk is not quantified, safety loses out to other more easily quantified objectives of a company. The fatal decision error that led to the Challenger accident is used as an example.     

A report of TRUSTNET on risk governance--lessons learned

During the 1990s, the current regulatory frameworks and decision making processes in the European Union for hazardous activities such as nuclear and chemical waste management, hazardous industrial facilities, food production, and genetically modified organisms (GMOs) in agriculture and health care, were confronted at both national and local levels with significant difficulties in trying to meet the different concerns of the various categories of stakeholders involved. The TRUSTNET concerted action was established to assess these difficulties and their consequences and to propose more coherent, comprehensive and equitable approaches for evaluating, comparing and managing health and environmental risks. This paper presents the outcomes of this programme. A European network of some 80 participants was established comprising an interdisciplinary team of regulators, experts and stakeholders with experience of industrial, natural and medical risks. The participants identified the main challenges to the governance of hazardous activities on the basis of a detailed analysis of some 11 case studies, and determined criteria for assessing what can be considered as 'good' governance of hazardous activities. As a result of these investigations, an interdisciplinary model describing the available approaches to governance of hazardous activities is proposed in the form of two main paradigms: Top-Down Governance and Mutual Trust Governance. Using this model the difficulties encountered by current approaches to risk regulation are interpreted. The new perspective describes how the two paradigms can interact in the continuous social dynamic to allow the maintenance of social cohesion.     

Comprehensive indicators of traffic-related premature mortality

Motor vehicle circulation is associated with multiple social benefits; nevertheless, it is widely acknowledged that it also produces a variety of adverse health effects, of which the most relevant are associated with mortality from road accidents and exposure to atmospheric pollution. Though in Chile these impacts have been quantified and evaluated independently, no indicators have been developed so far to account for this activity’s global impact on public health, or to express the individual impact that can be attributed to each vehicle category. In order to fill this void, the present study aimed at designing and quantifying indicators that account for the global impact on health that different motor vehicle categories impose on Chilean society. Health impact was quantified as the number of expected premature deaths caused by road accidents and exposure to atmospheric pollutants. Total premature mortality was understood as the total annual deaths that occurred as a consequence of road accidents and the exposure to O₃ and PM_2.5 derived from traffic-related emissions of its precursors. All estimations were made considering Chile’s Metropolitan Region in 2005 as a basic scenario. Differentiated indicators were obtained for 15 vehicle categories as a function of different parameters: traveled kilometer, vehicle, and vehicle lifetime. According to our results, when the health impact of traffic accidents and exposure to traffic-related air pollution are considered simultaneously, major differences were observed with the indicators traditionally used by regulators involved in the traffic-related decision-making process. The implications of our results on risk management strategies are discussed.     

A multi-attribute approach to assess homeland security risk

The United States Department of Homeland Security manages a wide spectrum of risks involving crime, terrorism, accidents, and natural disasters. This paper supports disaster management by identifying which attributes should be used to describe risks comprehensively and assessing the need to incorporate such multiattribute information into risk management processes. Attributes for describing homeland security risks were selected through a literature review. These attributes were then used in a risk assessment of homeland security hazards that informed risk ranking sessions conducted with members of the general public. The results taken together support the use of a range of attributes and perspectives. While aspects of life/health and economic damage were considered most important by both experts and the lay public, other attributes were of widespread importance, including attributes related to dread and uncertainty. These results demonstrate how to present risks in a deliberative risk management process and the importance of doing so using a complete set of attributes to describe the risks.     

Failed technology futures: pitfalls and lessons from a historical survey

Images of the future, with hindsight, turn out to be either right or wrong. In this article, past images of the impact of Information and Communication Technology (ICT) on traffic and transportation are investigated. Informed by the field of technology studies, seven key features are formulated that point at pitfalls and neglected aspects in many future expectations on technological developments and their societal impact. It is also argued that the evolution from broad sweeping promises to more down-to-earth assessments is inherent in technological developments, because expectations and diffuse scenarios also play a performative role in technological developments.     

From objective to constituted risk: an alternative approach to safety in strategic technological innovation in the European Union

Safety is a legitimate means of limiting technological innovation in our societies. However, the potential socio-economic impact of curtailing techno-industrial progress on the grounds of safety means that risk governance policies tend to restrict the range of legitimate approaches to safety on the principle that it can only be discussed in the frame of an allegedly objective scientific representation of risk. In European risk governance, socio-economic factors such as the underlying innovation rationales and goals are not openly considered to be related to the constitution of safety, but tend largely to be treated as factors of subjective reaction towards risk and technology. This paper seeks to overcome that approach by proposing a ‘constitutive’ understanding of how risk and socio-economic factors and dynamics relate, focusing in particular on the ‘safe and responsible’ development of nanotechnology in the European Union (EU). I argue that risk is constituted according to socio-economic considerations, and that the controllability of the environmental and health risks of nanotechnology in the EU is assumed on principle in the very strong institutional commitment to the industrial exploitation of nanotechnology R&D. Using a constitutive approach, we may legitimately conceive a broader set of potential safety scenarios, while at the same time highlighting major obstacles to implementing more critical constitutions of techno-industrial risk in the framework of a highly competitive knowledge-based global economy.     

Self‐Insurance and Self‐Protection as Public Goods

Many public goods provide utility by insuring against hazardous events. Those public goods can have self‐insurance and self‐protection character. For both situations we analyze the efficient public provision level and the provision level resulting from Nash behavior in a private provision game. We consider the interaction of public goods as insurance devices with market insurance. The availability of market insurance reduces the provision level of the public good for both public and private provision, regardless of whether we consider self‐insurance or self‐protection. Moreover, we show that Nash behavior has always a larger impact than the availability of market insurance.     

Location of hazardous materials plants in Israel

The study described in this article examines the distribution of hazardous materials plants in Israel during 2002–2010. In particular, it focuses on densely populated areas destined for future urban expansion, areas in proximity to rivers and water sources, and main transportation arteries. The survey identified certain hazardous materials plants (representing 10% of all such plants in Israel) as highly dangerous owing to the kinds of substances they contain, the nature of their industrial activities, and potential environmental hazards. The location of hazardous plants showed a correlation between population density and industry, with the highest concentration of plants found in Tel Aviv (30%), Haifa and adjacent industrial areas (25%), and Ashdod (12%). Significant concentrations of hazardous plants were also found in Ramat Hovav, Netanya, and Acre (Akko). From 2000 to 2010, the number of hazardous materials plants known to the Ministry of Environmental Protection increased by 62%, with most of the increase concentrated in such coastal cities as Haifa and Tel Aviv, the rest in Israel’s northern and southern (Negev) regions. Further analysis of these data revealed problems resulting from the proximity of these sites to potable and irrigation water sources and to transportation arteries. The main purposes of the study were, first, to develop a geo-tool for informed decision-making regarding the location of hazardous materials plants, and, second, to examine the distribution of such plants in Israel in order to prevent future industrial accidents. This article is part of a comprehensive study on the role of environmental policy in the planning of hazardous materials plants in Israel.     

Measuring the market impact of hedge funds

Hedge funds often employ opportunistic trading strategies on a leveraged basis. It is natural to find their footprints in most major market events. A “small bet” by large hedge funds can be a sizeable transaction that can impact a market. This study estimates hedge fund exposures during a number of major market events. In some episodes, hedge funds had significant exposures and were in a position to exert substantial market impact. In other episodes, hedge fund exposures were insignificant, either in absolute terms or relative to other market participants. In all cases, we found no evidence of hedge funds using positive feedback trading strategies. There was also little evidence that hedge funds systematically caused market prices to deviate from economic fundamentals.     

A systematic review of risk management in innovation-oriented firms

Innovation and risk are inseparable. In fact, literature on innovation management often recommends that innovation-oriented firms must actively monitor, evaluate, analyze and treat future events in order to mitigate risks whenever possible. This approach is particularly important in emergent economies characterized by unstructured national innovation systems and constant economic and market instability. However, there has been no systematic effort to identify and categorize risks that potentially impact businesses based on innovation. Thus, we propose an interpretative framework of risk events with potential financial impact in innovation-oriented firms constructed and tested by means of a mixed studies review. The risk events were identified through a comprehensive systematic search and review of the published literature on risk and innovation. From the 115 works that were analyzed, it was possible to identify nine categories of risk events frequently associated with innovation-oriented businesses that may generate financial impacts. The proposed interpretative framework was tested in an empirical study with 13 innovation-oriented firms located in six Brazilian technological parks. Results from the empirical study suggest that managers found the proposed interpretative framework complete and comprehensive. Moreover, the empirical study signaled which risk events are more relevant for the Brazilian context. The proposed framework is a first necessary step for future development of ERM models applicable in innovation-intensive contexts.     

Dis-Ag-reement: the construction and negotiation of risk in the Swedish controversy over antibacterial silver

What constitutes a potentially hazardous object is often debated. This article analyses the polemic construction and negotiation of risk in the Swedish controversy over the use of antibacterial silver in health care and consumer products. This debate engages the media, government agencies, parliament and government, non-governmental organizations and companies. Texts and websites from these actors were studied using content analysis. Antibacterial silver is construed by some actors as a risk object with harmful effects on a series of objects at risk: the environment, public health, organisms and sewage treatment. In contrast, other actors deny that antibacterial silver is a risk object, instead construing it as mitigating risk. In such a schema, antibacterial silver is conceived of as managing the risk objects of bacteria and micro-organisms, in turn managing the risk objects of infection, bad smell and washing, and in turn helping the environment and public health (objects at risk). The structure of the debate suggests two basic modes of risk communication. First, antibacterial silver is construed as a risk object, endangering a variety of objects at risk, such as organisms, public health, the environment and sewage treatment. Second, this association between antibacterial silver and objects at risk is obstructed, by denying that antibacterial silver is a risk object or by associating silver with the benefit of mitigating risk.     

Neglected and overemphasized risks: the opinions of risk professionals

Research on risks has mainly been devoted to detailed analyses of such risks that are subject to public debate and policy decision making. However, many if not most of the risks that are now the subject of regulation were once neglected. Experts in conjunction with regulators have a crucial role in putting risks on the policy agenda. But what views do experts have on the matter of attention to risks? In order to answer this question risk assessment experts were asked to list the risks they considered to be over‐emphasized, respectively neglected. Radiation risks constituted the largest category of risks reported to be over‐emphasized. Other risks often reported to be over‐emphasized included BSE, GMOs, amalgam, and air traffic. Lifestyle risks were the largest category of risks reported to be neglected. Other risks often listed as neglected included radon (as an exception within the radiation category), road traffic, socio‐economic risks, energy production excluding nuclear power, and local accidents (including fires and workplace accidents). Risks mentioned about equally often as neglected and over‐emphasized included chemicals and crime. There was a correlation between perceived risk and neglect: risks considered to be neglected were also judged as larger. For a comparison, the topics of articles in the journal Risk Analysis from 1991–2000 were categorized into the same risk categories that were used for the questionnaire. The risks most commonly treated in the journal (chemicals and cancer) coincided with the risks which experts in our survey considered to be overemphasized rather than neglected.     

Perception of technological risk: insights from research and lessons for risk communication and management

Technology has become a familiar companion in all areas of life. Production consumption, administration, education, communication, and leisure activities are all shaped by the use of technologies. However, people often associate with the term ‘technology’ attributes, such as catastrophic and potentially dangerous, and tend to take the benefits of technological products for granted. This asymmetry in risk–benefit perception is one of the main reasons why many consumers are concerned about ‘hidden’ risks of technologies and why they demand stringent regulatory actions when they feel unduly exposed to potential emissions or waste products associated with the lifecycle of technologies. This situation is often aggravated by social amplification processes, by which even small risks receive high media attention and are blown out of proportion in the public arena. At the same time, however, one needs to acknowledge that many technologies have the potential to harm the human health and the environment. The purpose of this article is to review our knowledge about risk perception with respect to technologies, in particular emerging technologies, and to suggest possible strategies to use this knowledge for improving our risk management practice. Technological risk perception is defined in this article as the processing of physical signals and/or information about a potentially harmful impact of using technology and the formation of a judgment about seriousness, likelihood, and acceptability of the respective technology. Based on the review of psychological, social, and cultural factors that shape individual and social risk perceptions, we have attempted to develop a structured framework that provides an integrative and systematic perspective on technological risk perception and that may assist risk management and regulation in taking perceptions into account.     

The Emergence of Corporate Governance from Wall St. to Main St.: Outside Directors, Board Diversity, Earnings Management, and Managerial Incentives to Bear Risk

Recent corporate events have brought a heightened public awareness to corporate governance issues. Much work has been accomplished to date, but it is clear that much more remains to be done. This paper provides a review of empirical research in four relevant areas of corporate governance. Specifically, the paper provides an overview of (a) the role that outside directors play in monitoring managers, (b) the emerging literature on the impact of board diversity, (c) the existence of and incentives for corporate executives to manage firm earnings, and (d) managerial incentives to bear risk.     

A GIS-based tool for the management of industrial accidents triggered by volcanic ash fallouts

In this last decade, worldwide attention has been focused on the hazards derived from the interaction between extreme natural phenomena and critical infrastructures and/or chemical and process industry (natural–technological hazards or Na-Tech). Due to the recent occurrence of significant events, great attention has also been given to Na-Tech hazards triggered by volcanic eruptions; in particular, the eruption of the Icelandic volcano alarmed the European community due to the ash fallout over the continent, which caused significant problems for the population, road, rail and air traffic and production activities. This study aims at defining a procedure for the representation of the vulnerability of industrial facilities to potential volcanic ash fallouts. Its implementation on a Geographical Information System has also been executed and a semi-automatic procedure for the vulnerability mapping has been constructed.     

Feeding everyone: Solving the food crisis in event of global catastrophes that kill crops or obscure the sun

Mass human starvation is currently likely if global agricultural production is dramatically reduced for several years following a global catastrophe, e.g. super volcanic eruption, asteroid or comet impact, nuclear winter, abrupt climate change, super weed, extirpating crop pathogen, super bacterium, or super crop pest. This study summarizes the severity and probabilities of such scenarios, and provides an order of magnitude technical analysis comparing caloric requirements of all humans for 5 years with conversion of existing vegetation and fossil fuels to edible food. Here we present mechanisms for global-scale conversion including natural gas-digesting bacteria, extracting food from leaves, and conversion of fiber by enzymes, mushroom or bacteria growth, or a two-step process involving partial decomposition of fiber by fungi and/or bacteria and feeding them to animals such as beetles, ruminants (cattle, sheep, etc.), rats and chickens. We perform an analysis to determine the ramp rates for each option and the results show that careful planning and global cooperation could maintain humanity and the bulk of biodiversity.
