In June 1990, SHP magazine published an article by Chris Steel on risk estimation. The article stated that techniques for estimating the magnitude of risks are many and varied and can be developed for a particular industry. All techniques involved some degree of subjectivity though, and relied on past events to predict future responses. Chris put forward the Hazard Number Rating as another way of estimating risk.
Tomorrow, SHP Online will publish a follow up article from Derek Coulson, who looks back at Chris Steel’s original and examines how risk estimation can be used 25 years on.
