Читать книгу Risk Assessment - Marvin Rausand - Страница 166

Deciding on whether the risk should be reduced, how it should be done, and ensuring that risk reduction measures are implemented is not part of the risk assessment, but is left to the wider risk management process. Still, it is a part of risk assessment to provide decision‐makers with a basis for making these decisions. Identification and evaluation of potential risk reduction measures should, therefore, be included.

Based on our understanding of why and how accident scenarios can develop, we can also identify risk reduction measures. Three main principles for reducing risk may be used:

 Prevent the initiating events from occurring.

 Reduce the probability of the initiating events.

 Reduce the consequences of the initiating events.

These principles are based on the accident model implemented in the bow‐tie, where the three principles address the bow‐tie from left to right. Chapter 14 discusses risk reduction measures in more detail and presents methods for identifying and evaluating the measures.
