of new machinery and chemicals came a wide range
of hazards. The conventional OSH legislation became
limited; in 2002 (figure 11), more than 60 per cent
of work-related fatalities actually occurred without
violating the OSH legislation. In addition, the type of
employment structure was also changing gradually, with
the number of temporary and contract-based workers
expanding. This increased fluidity of workers meant an
increase in the number of inexperienced workers. The
problems were further compounded by the retirement
of workers and managers of the baby-boomer generation
who had tacit OSH knowledge and experiences at the
workplace. With such OSH trends, it became apparent
that a voluntary and systematic approach to find
potential risks was needed.
