This paper is the continuation of a previous one, in which a new technique was proposed for the investigation and analysis of occupational accidents. The first paper (Part I) described WAIT (Work Accidents Investigation Technique) in some detail and provided a practical example of its application.
This second paper (Part II) reports empirical work carried out for testing the performance of WAIT, in terms of its applicability and coverage. It starts with a brief summary of the technique’s investigation process, followed by a description of how the method was tested in real conditions through its application, in situ, to the investigation of 56 accidents that occurred in 16 industrial firms of various sizes and from a diversity of industrial sectors. Some aggregated statistical results are presented and discussed. It provides evidence that WAIT was able of capturing the applicable problem-areas and covering relatively well a wide range of situations (from simple to complex accidents). The use of some new harmonised variables, being introduced by the Eurostat for the production of European statistics, is also addressed. Certain problems associated with one of these variables are identified and commented upon. A forthcoming paper (Part III) will address more specific studies, providing a preliminary insight on the techniques’ validity and reliability.
