chapter 1. introduction to disaster risk management
identifi ed the possible risks, it is necessary to consider possible causes
and scenarios, as there are many ways an event can occur. Approaches
used to identify risks include checklists, judgments based on experience
and records, fl ow charts, brainstorming, systems analysis, scenario
analysis and system engineering techniques.
Risk Analysis
Risk analysis aims to establish an understanding of the level of risk and
its nature. It involves consideration of the sources of risk, their positive
and negative consequences and the likelihood that those consequences
may occur. Factors that affect consequences and likelihood may be
identifi ed. Risk is analyzed by combining consequences and their
likelihood. Identify the existing processes, devices or practices that
act to minimize negative risks or enhance positive risks and assess
their strength and weaknesses. The magnitude of consequences of an
event, should it occur, and the likelihood of the event and its associated
consequences, are assessed. These will be considered in the context
of the existing strategies and controls. Consequences and likelihood
are combined to produce a level of risk.
Risk Prioritization
The purpose of risk prioritization is to analyze and identify priority areas
for action. Decisions may include whether a risk needs treatment,
whether an activity should be undertaken, and what should be the
priorities for treatment. Decisions would be based on the level of risk,
specifi ed consequences, the likelihood of specifi ed events or outcomes,
and the overall effect of multiple events. In some circumstances, the
risk prioritization may lead to a decision to undertake further analysis.
Risk Treatment
Risk prioritization provides a list of risks requiring treatment. Risk
treatment involves identifying strategies for treating these risks,
evaluating those options, preparing treatment plans and implementing
them. Before appropriate treatment actions can be determined, the
analysis of each risk may need to be revisited and extended to draw
out the information needed to identify and explore different treatment
options. It is particularly important to identify the causes of the risks so
these are treated and not just the symptoms. Risk treatment may itself
introduce new risks that need to be identifi ed, assessed, treated and
monitored.
