In 5.2.1 to 5.2.5. the different parts of risk management are defined and described. 5.2.1 DefInition of scope When performing a risk analysis, the scope shall be defined. i.e. the system that is to be included in the analysis. This includes definition of the boundary of the system and to identify user, intended use and reasonably foreseeable misuse. Assumptions and limitations for the analysis should also be defined. Technical, environmental, organisational and other aspects relevant for the problem/system should be included. 5.2.2 Hazard Identification Hazard identification involves systematic review of the system under study to identify the type of inherent hazards that are present together with the ways in which they could be realized. Different hazards and sources of risks shall be identified and the type of hazard they pose analysed. Hazard identification methods fall mainly into three categories: 1) Comparative methods (e.g. checklists, hazard indices and reviews of historical data) 2) Fundamental methods, that are structured to stimulate a group of people to apply foresight in conjunction with their knowledge to the task of identifying hazards (e.g. HAZOP studies, ISO 12100 and FMEA) 3) Inductive reasoning techniques (e.g. event tree logic diagrams) The significance of the sources of risks shall be analysed by an initial evaluation, based on a consequence analysis. The aim of this analysis is to decide whether: a) Actions should be taken to eliminate or reduce the hazard b) The analysis can be terminated due to the insignificance of hazard c) The analysis should be continued with a risk estimation There are many factors influencing the risk management. e.g. the storage capacity, annual SRF turnover and complexity of on-site handling and to consider all the variables that might be valid for a facility. 5.2.3 Risk estimation Risk estimation should examine the initiating events or circumstances, the sequence of events that are of concern, any mitigating features and the nature and frequency of the possible deleterious consequences of the individual hazards to produce a measure of the level of the risk being analysed. The measures could address human, property or environmental risks and should include an indication of the uncertainty associated with the estimates. The risk estimation process can be described by...
