||The level of potential losses that a society or community considers acceptable, given existing social, economic, political, cultural, technical and environmental conditions.
|Assets and values
||Recognised features of the built, natural and cultural environments. Built assets may include buildings, roads and bridges; structures managed by utility and service providers; or recognised features of private land, such as houses, property, stock and crops and associated buildings and equipment. Natural assets may include forest produce, forest regeneration, conservation values including vegetation types, fauna, air and water catchments*. Cultural values may include recreational, Indigenous, historical, archaeological and landscape values.
||A conclusion that is reached based on the information available at the time.
||A group of people with a commonality of association and generally defined by location, shared experience or function.
|Community based disaster risk management
||A process that seeks to develop and implement strategies and activities for disaster preparedness (and often risk reduction) that is locally appropriate and locally ‘owned’.
||Outcome or impact of an event.
||Critical infrastructure includes those services, physical facilities, supply chains, information technologies and communication networks that, if destroyed, degraded or rendered unavailable for an extended period, would significantly impact on the social or economic well-being of the community.
Adapted from Critical Infrastructure Advisory Council (CIAC).
- electrical power systems
- gas and oil storage and transportation
- banking and finance
- water supply systems (and sewerage).
|Elements at risk
||The population, buildings and civil engineering works, economic activities, public services and infrastructure etc. exposed to sources of risk.
||An event, actual, or imminent that endangers or threatens to endanger life, property or the environment, and that requires a significant and coordinated response.
(Essential Services Commission Act 2001)
|A service (including the supply of goods) provided by:
- the electricity industry
- the gas industry
- the ports industry
- the grain handling industry
- the rail industry
- the water industry
- (g) any other industry prescribed for the purpose of this definition.
||Occurrence of a particular set of circumstances. An incident or situation that occurs in a particular place during a particular interval of time.
||A measure of the number of occurrences per unit of time.
||Comes under the definition of an Emergency. The Emergency Management Act 1986 defines ‘emergency’ as: “… the actual or imminent occurrence of an event which in any way endangers or threatens to endanger the safety or health of any person in Victoria or which destroys or damages, or threatens to destroy or damage, any property in Victoria or in any way endangers or threatens to endanger the environment or an element of the environment in Victoria, including, without limiting the generality of the foregoing and specific to integrated fire management and therefore includes:
- A fire; and
- An explosion,
- A road accident or any other accident,
- A disruption
||A source of potential harm or situation with a potential to cause loss.
A potentially damaging physical event that may cause loss of life or injury, property damage, social and economic disruption or environmental degradation.
||A subgroup of the broader committee comprising the risk category, technical knowledge and experience.
||Used as a general description of probability or frequency – can be expressed qualitatively or quantitatively.
||Any negative consequence or adverse effect – financial or otherwise.
||Measures taken in advance of a disaster, aimed at decreasing or eliminating its impact on society and environment.
||To check, supervise, critically observe or measure the progress of an activity, action or system on a regular basis in order to identify change from the performance level required or expected.
||Group of people and facilities with an arrangement of responsibilities, authorities and relationships.
||What is realistic to achieve in the context of:
- the severity of the hazard or risk in question
- the state of knowledge about that hazard or risk and any ways of
- removing or mitigating that hazard or risk
- the availability and suitability of ways to remove or mitigate that
- hazard or risk
- the cost of removing or mitigating that hazard or risk.
||Arrangements to ensure that in the event of an emergency occur all those resources and services that are needed to cope with the effects can be efficiently mobilised and deployed.
||Regulatory and physical measures to ensure that emergencies are prevented, or their effects mitigated.
||A measure of the chance of occurrence expressed as a number between 0 and 1. ‘Frequency’ or ‘likelihood’ rather than ‘probability’ may be used in describing risk. The likelihood of a specific outcome, as measured by the ratio of specific outcomes to the total number of possible outcomes. Probability is expressed as a number between zero and unity – zero indicating an impossible outcome and unity indicating an outcome that is certain. Probabilities are commonly expressed in terms of percentage e.g. the probability of throwing a six on a single roll of a die is 1 in 6, or 0.167, or 16.7 per cent.
||The coordinated process of supporting emergency affected communities in the reconstruction of the physical infrastructure and restoration of emotional, social, economic and physical wellbeing.
||Risk remaining after implementation of risk treatment.
||The capacity of a system, community or society potentially exposed to hazards to adapt, by resisting or changing in order to reach and maintain an acceptable level of functioning and structure. This is determined by the degree to which the social system is capable of organizing itself to increase its capacity for learning from past disasters for better future protection and to improve risk reduction measures
||Actions taken in anticipation of, during and immediately after an emergency, to ensure its effects are minimised and that people affected are given immediate relief and support.
||The chance of something happening that will have an impact on objectives.
The probability of harmful consequences resulting from interaction between natural or human-induced hazards and vulnerable conditions6.
||Systematic process to understand the nature of, and deduce, the level of risk.
||The overall process of risk identification, analysis and evaluation
||Terms of reference by which the significance of risk is assessed.
||Process of comparing the level of risk against risk criteria.
||The process of determining what, where, when, why and how something could happen.
||The culture, process and structures that are directed towards realising potential opportunities whilst managing adverse effects.
|Risk management process
||The systematic application of management of policies, procedures and practices to the tasks of communicating, establishing the context, identifying, analysing, evaluating, treating, monitoring and reviewing risk.
||Actions taken to lessen the likelihood, negative consequences, or both, associated with a risk.
||A listing of risk statements describing sources of risk and elements at risk, with assigned consequences, likelihoods and levels of risk.
||Process of selection and implementation of measures to modify risk. The term ‘risk treatment’ is sometimes used for the measures themselves.
|Source of risk
||Source of potential harm.
||Those people and organisations who may affect, be affected by, or perceive themselves to be affected by a decision, activity or risk.
||The potential to be affected by loss.
||A risk within a range that society can live with so as to secure certain net benefits. It is the range of risk regarded as non-negligible and needing to be kept under review and reduced further if possible.
||An existing process, policy, device, practice or other action that acts to minimise negative risk or enhance positive opportunities. The word control may also be applied to a process designed to provide reasonable assurance regarding the achievement of objectives.
|Treatment (adequacy) assessment
||Systematic review of processes to ensure that controls are still effective and appropriate.
||The conditions determined by physical, social, economic and environmental factors or processes, which increase the susceptibility of a community to the impact of hazards.
|Vulnerable people (DHHS definition)
||Those living in high bushfire risk areas and who are unable to make an independent decision, including due to cognitive impairment; physically dependant and totally reliant on in home personal care and support; and people who live alone and are geographically and socially isolated with no co-resident carer or family.
