Book Description
Why do mine disasters continue to occur in wealthy countries when major mine hazards have been known for over 200 years and subject to regulation for well over a century? What lessons can be drawn from these disasters and are mine operators, regulators and others drawing the correct conclusions from such events? Why is mining significantly safer in some countries than in others? Are the underlying causes of disasters substantially different from those that result in one or two fatalities?This book seeks to answer these questions by systematically analysing mine disasters and fatal incidents in five countries (Australia, Britain, Canada, New Zealand and the USA) since 1992. It finds that there are 10 pattern causes which repeatedly recur in these incidents, namely:engineering, design and maintenance flaws,failure to heed warning signs,flaws in risk assessment,flaws in management systems,flaws in system auditing,economic/reward pressures compromising safety,failures in regulatory oversight,worker/supervisor concerns that were ignored,poor worker/management communication and trust, andflaws in emergency and rescue procedures.The vast majority of incidents entailed at least three of these pattern causes and many exhibited five or more. The book also demonstrates these pattern deficiencies are not confined to mining but can be identified in other workplace disasters including aircraft crashes, oil-rig explosions, refinery and factory fires, and shipping disasters. At the same time, the examination finds no evidence to support other popular explanations of mine safety which focus on behaviour, culture or complex technologies. It finds that there is little to differentiate the failures that lead to single death or multiple deaths and 'disaster' studies would benefit from also examining near misses.The book examines why pattern causes have proved so resistant to intervention by governments while also identifying instances where lessons have been learned. How, for example, do governments strike a balance between prescriptive regulation and risk management/system-based approaches? Only by understanding and modifying the political economy of safety can these problems be addressed. It concludes by proposing an agenda for change that will address pattern causes and contribute to safe and productive work environments.

Safe Performance in a World of Global Networks
Author: Jean-Christophe Le Coze
Publisher: Springer Nature
ISBN: 3031351630
Category : Technology & Engineering
Languages : en
Pages : 111
Book Description
This open access book provides an analytical and critical outlook, by leading scholars, of the impact of various trends in the quality of collaboration and resulting safety outcomes that arise from the evolution of traditional integrated production within a single firm into a complex web of partnerships and supply chains. In the face of increasing fragmentation within industrial production and the associated rise in the complexity of inter-organizational communication and transaction, this book analyses causal factors such as cost pressures, globalization of demand, increasingly flexible resource allocation and work organization, changes in legal liability and the possibilities afforded by information technology. Various case studies focus on the effects of crossing boundaries between organizations, between different trades and professions and between countries, assessing the effect of variations in regulatory structures and national cultures. Furthermore, they illustrate the wide range of organizational forms to be found in high-hazard industries today and the impact, potential or real, of the variety of forms of partnership on safety and well-being at work. The contributors assess the effect of out-sourcing and of various forms of partnership and governance on safety at work and how they can be made to support the prevention of major accident hazards.

The Routledge Handbook of Law and Death
Author: Marc Trabsky
Publisher: Taylor & Francis
ISBN: 1040166628
Category : Social Science
Languages : en
Pages : 368
Book Description
The Routledge Handbook of Law and Death provides a comprehensive survey of contemporary scholarship on the intersections of law and death in the 21st century. It showcases how socio-legal scholars have contributed to the critical turn in death studies and how the sociology of death has impacted upon the discipline of law. In bringing together prominent academics and emerging experts from a diverse range of disciplines, the Handbook shows how, far from shunning questions of mortality, legal institutions incessantly talk about death. Touching upon the epistemologies and materialities of death, and problems of contested deaths and posthumous harms, the Handbook questions what is distinctive about the disciplinary alignment of law and death, how law regulates and manages death in the everyday, and how thinking with law can enrich our understandings of the presence of death in our lives. In a time when the world is facing global inequalities in living and dying, and legal institutions are increasingly interrogating their relationships to death, this Handbook makes for essential reading for scholars, students, and practitioners in law, humanities, and the social sciences.

The Regulation and Management of Workplace Health and Safety
Author: Peter Sheldon
Publisher: Routledge
ISBN: 0429560664
Category : Business & Economics
Languages : en
Pages : 208
Book Description
The book provides a collection of cutting-edge, multi-disciplinary research-based chapters on work, workers and the regulation and management of workplace health and safety. Featuring research from Australia, Europe and North America, the chapters traverse important historical examples and place important, emerging contemporary trends, like work in the gig economy, into wider international and historical perspectives. The authors are leading authorities in their fields. The book contributes to advancing our knowledge – empirical and theoretical – of the ways in which labour market dynamics, management strategies, state regulation and public policy, and union organisation affect outcomes for workers. It features in-depth exploration of, and reflection on, some of the major labour market challenges facing workers, and analysis of strengths and weaknesses of responses to those challenges, whether via management, state regulation or collective employee voice. The chapters highlight shifts in in/equality of outcomes; access to security and flexibility at work; genuine access to workplace voice and decision-making; and the implications of different avenues and mechanisms for regulating work and employment. The text is aimed at researchers, undergraduate and postgraduate students in work and organisational studies, industrial/employment relations and human resource management, workplace (or occupational) health and safety, employment law, and labour history. It will also be of particular interest to policy makers and practitioners working in the field of workplace health and safety.

Managing People in Organizations
Author: Thomas Klikauer
Publisher: Bloomsbury Publishing
ISBN: 1352004070
Category : Business & Economics
Languages : en
Pages : 278
Book Description
This new and engaging core textbook offers a unique line manager perspective that presents students with HRM topics and issues that they will be confronted with once they enter the world of work in a managerial role. It is a concise text that focuses on providing students with all they need to know to equip them with a comprehensive understanding of the role the (non-HR) manager plays in the day-to-day running of an organization. The author's deep understanding and wide-ranging knowledge of the subject matter means that the text is firmly founded on the latest research, while the case studies, topical and international examples, and experiential exercises that form a fundamental part of the book ensure that theory is always clearly applied to real-world practice. This text is an essential companion for MBA and postgraduate students who are studying modules on Human Resource Management or Managing People but who are non-HRM specialists and do not require the exhaustive detail found in other HRM texts. It is also suited for use alongside upper-level undergraduate modules on these topics on mainstream business degrees.
