10、echnical terms that might differ, there are also underlying concepts and theories, as well as various methods for analysis and investigations. The aim of this paper is to compare and discuss differ- ent definitions and c

13、 a lot of competing definitions of terms. One essential source for technically oriented terms is an IEC-standard [1], which has given a set of related terms. However, this does not include all aspects, and there are al-

14、ternatives to the viewpoints in the standard. Just a small selection of the definitions in the safety area will be given here. However, it should be noted that defini- tions are formulated in different ways. They could:?

15、 give a simple statement of the meaning of a term, and/ or ? sum up all elements which usually is included in practical use, and/or ? include the good characteristics aiming at perfect results.The first type of definitio

16、ns might be classified as descrip- tive, and others as normative (saying how it should be done).0304-3894/$ – see front matter © 2004 Published by Elsevier B.V. doi:10.1016/j.jhazmat.2004.02.003L. Harms-Ringdahl / J

17、ournal of Hazardous Materials 111 (2004) 13–19 15However, many companies do not have a formulated pol- icy (especially SME), but they have safety management to deal with their hazards, in one way or another. Accordingly,

18、 there is a need for a comprehensive and descriptive defini- tion. One suggestion for a simple definition of occupational health and safety management—a systematic way of man- aging the occupational health and safety ris

21、companies, and large chemical industries, which often are associated with a potential for major accidents and also rigorous SMS. On the other hand, you can have more uncomplicated types of production, where minor acciden

22、ts are frequent and safety is managed in a much more relaxed way.Table 1 gives a summary of parameters defining differ- ent situations. In discussions of advanced safety features, you can easily get trapped by a stereoty

23、pe related to Group A. It is easy to focus on the first type and neglect the second type, which produces much more injuries and dam- ages (e.g. [5]). It is a reason, why also less sophisticated applications have been con

24、sidered in the section about definitions. It should be noted that a specific company or organi- sation could have parameters in both groups at the same time. For example, the company has a formal safety man- agement syst

31、r more recognised analysis methods, of which there a large amount published in the literature [5,10,11]. Also for investigations of accidents there are several meth- ods in use. According to a recent study in Europe [12]

32、, the use of methods is less common and self-evident compared to applications in risk analysis.3.4. Concepts and theoriesExplanations and theories about accidents and their pre- vention are numerous. They are essential a

33、lso in the practical world, as they influence how (safety) management systems are designed, the application of risk analysis tools, and the accomplishment of event investigations. Hale [9] points out that there is some c

34、onsensus for the two first “ages” of safety, which are related to technical and human failures respectively. In the third “age”, with concern for complex socio-technical and safety management systems, developments are st

35、ill in an early stage. Although there might be a basic agreement in the scientific community concerning technical and human failures, as a whole the variation on conceptions about accident causation is large. An interest

36、ing aspect is the coupling between accident models and how an event analysis is accomplished. Holl- nagel [13] has made a classification of methods in accident investigations, which are divided in three major groups. The

37、 first is “Sequential accident models”, which describe the ac- cident as the result of a sequence of events in a specific or- der, e.g. the Domino theory. Such models often turned out to be limited in their capability to

38、 explain what happened in more complex systems. “Epidemiological accident models” describe an accident in analogy with a disease, i.e. as a combination of “agents” and environmental factors that can generate unhappy cond
