National Emergency Risk Assessment Guidelines

This is one of the simplest yet all encompassing guides to the principles of risk management and the risk management tools involved that I have come across. Produced for Emergency Services personnel to assess disasters and emergencies, the principals and tools are relevant to any situation or workplace hazard. It cover the use of tools such as ALARP, Risk Assessment Matrix, Bow Tie Diagram, Risk Curves, Risk Registers, Brainstorming and Risk Workshops with some simple examples.

For anyone trying to get their head around the new risk management standard and using tools such as the bow tie diagram to conceptualise risk and controls this document will be extremely useful.

This document was developed as part of the Australian Emergency Management Committee’s implementation of the
National Risk Assessment Framework. The development was undertaken by the Tasmanian State Emergency Service, on
behalf of the National Risk Assessment Advisory Group.

Extract:

In identifying risks, it is important to reveal the interrelationship of sources of risks and impacts. The preferred tool for this is the bow-tie diagram, which can be used to identify: (a) pathways leading to the emergency and the actual impacts; and (b) prevention/preparedness and response/recovery
controls. It conceptualises the sources, causes, controls and impacts of an emergency event, the details of which are then captured in the risk register. The bow-tie diagram combines advantages of team-based brainstorming and of more structured techniques, such as systems analysis, because it is a graphical representation of the relevant emergency scenario. It depicts the storyline for a loss to the community, which identifies areas that are critical in controlling risk(s).
