Demonstrates an effective method for quantifying consequences and likelihoods of risks, as well as for combining these assessments. Different kinds of risks are examined: death, injury and illness; economic; social; environmental; symbolic; external; and reputational. The authors show how these can be rated and combined, allowing for a rich appraisal of a wide range of situations. It therefore becomes possible to construct much more sophisticated and quantified risk matrices to assist decision-making about allocation of resources and other responses. The chapter also shows that many of the qualitative methods currently in use are open to subjective and inconsistent interpretations.
