Chapter 3 Main Elements of Risk Assessment
3.1 Introduction
The terms “risk analysis” and “risk assessment” are used several times in Chapters 1 and 2 without any proper definition. We define the terms as follows:
Definition 3.1 (Risk analysis)
A systematic study to identify and describe what can go wrong and what the causes, the likelihoods, and the consequences might be.
A risk analysis is, according to Definition 3.1 , aimed at providing answers to the three questions used to define risk.
Definition 3.2 (Risk assessment)
The process of planning, preparing,
