Safety performance prevention through design

The safety audit is designed to take accoimt of quantitative information available through data on injuries, incident reports, insurance claims, accident reports, first aid records and any other documents that can provide an indication of performance. In looking at the administrative structure, attention is drawn to the support mechanisms that provide the foimdation for hazard management and accident prevention. 

Mishaps involve a set of causal factors that lead up to the final mishap event, and these factors are the actuated hazard conditions. Mishap causal factors can be identified prior to an actual mishap through the application of HA. Mishaps are an inevitable consequence of antecedent causes and, given the same causal factors, the same mishap is repeatable, with the frequency based on the component probabilities. Mishaps can be predicted via hazard identification, and they can be prevented or controlled via hazard elimination or hazard control methods. This safety concept demonstrates that we do have control over the potential mishaps in the systems we develop and operate. We are not destined to face an unknown suite of undesired mishaps, unless we allow it to be so (by not performing adequate system safety). In the safety sense, mishaps are preplanned events in that they are actually created through poor design and/or inadequate design foresight.
