Safety culture refers to the ways that safety issues are addressed in a workplace. It often reflects "the attitudes, beliefs, perceptions and values that employees share in relation to safety."〔Cox, S. & Cox, T. (1991) The structure of employee attitudes to safety - a European example Work and Stress, 5, 93 - 106.〕 In other words, "the way we do safety around here."〔ZCBI (1991) Developing a Safety Culture., Confederation of British Industry, London.〕 ==Definition== The Chernobyl disaster highlighted the importance of safety culture and the impact of managerial and human factors on safety performance.〔Flin, R., Mearns, K., O'Conner, P. & Bryden, R. (2000) Measuring safety Climate: Identifying the common features Safety Science 34, 177 - 192.〕〔IAEA, (1991) Safety Culture (Safety Series No. 75-INSAG-4) International Atomic Energy Agency, Vienna〕 The term ‘safety culture’ was first used in INSAG’s (1988) ‘Summary Report on the Post-Accident Review Meeting on the Chernobyl Accident’ where safety culture was described as: "That assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance." Since then, a number of definitions of safety culture have been published. The U.K. Health and Safety Commission developed one of the most commonly used definitions of safety culture: "The product of individual and group values, attitudes, perceptions, competencies, and patterns of behaviour that determine the commitment to, and the style and proficiency of, an organisation’s health and safety management".〔HSC (Health And Safety Commission), 1993. Third report: organising for safety. ACSNI Study Group on Human Factors. HMSO, London.〕 "Organisations with a positive safety culture are characterized by communications founded on mutual trust, by shared perceptions of the importance of safety and by confidence in the efficacy of preventive measures." The Cullen Report into the Ladbroke Grove rail crash saw safety culture as "the way we typically do things around here"; this would imply that every organisation has a safety culture – just some a better one than others. The concept of 'safety culture' originally arose in connection with major organisational accidents, where it provides a crucial insight into how multiple organisational barriers against such accidents can be simultaneously ineffective: "With each disaster that occurs our knowledge of the factors which make organisations vulnerable to failures has grown. It has become clear that such vulnerability does not originate from just ‘human error’, chance environmental factors or technological failures alone. Rather, it is the ingrained organisational policies and standards which have repeatedly been shown to predate the catastrophe."〔()〕 However it is now also applied (with less certain validity) to individual accidents, and hence has come to relate to a full range of safety behaviors from the wearing of PPE (or not), the quality of delivery of a tool box talk, the quality of shopfloor response to fault conditions – or (what is frequently the main concern for major accidents) the extent to which safety considerations influence high level meetings and management decisions. A new starter or recently arrived sub contractor will soon pick up what the local norms are and be heavily influenced by them. If a tipping point of around 90% compliance is observed then these individuals will be highly likely to comply too – but if these individuals observe a 50:50 split then they may feel they have free choice as whatever they do they won't stand out. The safety culture of an organization and its safety management system are closely related, but the relationship is not simply that the safety culture complies with the formal safety management system The safety culture of an organization cannot be created or changed overnight; it develops over time as a result of history, work environment, the workforce, health and safety practices, and management leadership: "Organizations, like organisms, adapt".〔 An organization’s safety culture is ultimately reflected in the way safety is addressed in its workplaces (whether boardroom or shopfloor). In reality an organization's safety management system is not a set of policies and procedures on a bookshelf, but how those policies and procedures are implemented into the workplace, which will be influenced by the safety culture of the organization or workplace.〔Kennedy, R. & Kirwan, B., (1995) The failure mechanisms of safety culture. In: Carnino, A. and Weimann, G., Editors, 1995. Proceedings of the International Topical Meeting on Safety Culture in Nuclear Installations, American Nuclear Society of Austria, Vienna, pp. 281–290.〕 The UK HSE notes that safety culture is not just (nor even most significantly) an issue of shopfloor worker attitudes and behaviours "Many companies talk about ‘safety culture’ when referring to the inclination of their employees to comply with rules or act safety or unsafely. However we find that the culture and style of management is even more significant, for example a natural, unconscious bias for production over safety, or a tendency to focussing on the short-term and being highly reactive."〔(【引用サイトリンク】url=http://www.hse.gov.uk/humanfactors/topics/culture.htm )(see Aberfan disaster, Flixborough disaster, for two notable UK events that may have informed this view)〕 Since the 1980s there has been a large amount of research into safety culture. However the concept remains largely "ill defined".〔Guldenmund, F. W. (2000) The nature of safety culture: a review of theory and research Safety Science, 34, 215-257.〕 Within the literature there are a number of varying definitions of safety culture with arguments for and against the concept. Two of the most prominent and most-commonly used definitions are those given above from the International Atomic Energy Agency (IAEA) andfrom the UK Health and Safety Commission (HSC).〔 However, there are some common characteristics shared by other definitions. Some characteristics associated with safety culture include the incorporation of beliefs, values and attitudes. A critical feature of safety culture is that it is shared by a group.〔〔Pidgeon, N. & O'Leary, M. (2000) Man-Made Disasters: why technology and organizations (sometimes) fail. Safety Science, 34, 15-30〕 When defining safety culture some authors focus on attitudes, where others see safety culture being expressed through behaviours and activities.〔 The safety culture of an organization can be a critical influence on human performance in safety-related tasks and hence on the safety performance of the organization. Many proprietary and academic methods claim to assess safety culture, but few have been validated against actual safety performance. The vast majority of surveys examine key issues such as leadership, involvement, commitment, communication, and incident reporting. Some safety culture maturity tools are used in focus group exercises, though few of these (even the most popular) have been examined against company incident rates. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Safety culture」の詳細全文を読む スポンサード リンク
