ABSTRACT
This report has addressed some of the generic problems that arise in the extensive domain of safety, in particular in relation to policy designed to prevent harm to people, the environment and society; in other words, policy that is focused on risks. To do this, it proved necessary to differentiate this category further. In line with the practice in contemporary scientific literature, we have drawn a distinction between simple, complex, uncertain and ambiguous risk problems. These differ primarily in the degree to which there is uncertainty surrounding risks.
