Function type | Description | Possible states / values | Possible asset types |
---|---|---|---|
Damage state | The extent to which the asset is damaged. | See Table 3 | • Buildings • Electricity cables • Network junction point • Pipelines • Roads • Telecommunication cables • Waterways |
Exposed state | Whether or not an asset is exposed to the hazard | -1 – Unknown: Outside of the modelled area 0 – Not exposed: Inside the modelled area but hazard indicates zero intensity 1 – Exposed: Inside the modelled area and greater than zero hazard intensity | All |
Functional downtime | Productive time lost due to the impact of the hazard on the asset. | Person-days | • Buildings • Electricity cables • Network junction point • Pipelines • Roads • Telecommunication cables • Waterways |
Human displacement | A measure of the extent to which humans and human activities are displaced by exposure of the asset to the hazard. | 0 – None: No or minimal evacuation necessary (less than 1 day). 1 – One day to 1 week: Evacuation necessary but reoccupation possible after less than a week. 2 – One week to 1 month: Evacuation necessary and reoccupation not possible for between a week and a month. 3 – One month to 6 months: Evacuation necessary and reoccupation not possible for between 1 and 6 months. 4 – Greater than 6 months: Evacuation necessary and reoccupation not possible for more than 6 months. | Buildings (people are assigned to buildings, with day and night-time occupancy rates as one of the building attribute types) |
Human losses | A measure of the detrimental effect on humans who are present in or at a asset. | No or light injury: The person is either uninjured or only injured in ways that can be treated without trained medical assistance. Moderate injury: The person is injured such that they require expert treatment (paraprofessional or doctor), but which are not immediately life threatening if such treatment is not available Serious injury: The person is injured such that they require a greater degree of medical care and use of medical technology such as x-rays or surgery, but not expected to progress to a life threatening status, full recovery expected with suitable treatment. Critical injury: The person sustains injuries that pose an immediate life threatening condition if not treated adequately and expeditiously, or long-term disability. Dead: The person sustains injuries leading to immediate death. | Buildings (people are assigned to buildings, with day and night-time occupancy rates as one of the building attribute types) |
Human susceptibility | The susceptibility to injury of a hypothetical human present in or at this asset. | 0 – Insignificant: The hazard will not threaten anyone; only those who deliberately put themselves at risk are susceptible to injury. 1 – Low: Only those caught in exceptional circumstances are susceptible to injury. 2 – Medium: Only the most vulnerable are directly susceptible to injury. 3 – High: Those who can move to a protective environment are unlikely to be susceptible to injury but others will be. 4 – Extreme: Even fit able-bodied people are highly likely to be susceptible to injury | Buildings (people are assigned to buildings, with day and night-time occupancy rates as one of the building attribute types) |
Reinstatement cost | Encompasses all direct costs caused by exposure of the asset to the hazard | Asset Repair Cost: Costs incurred in restoring the asset to its pre-event state Contents Repair Cost: Costs incurred in returning the contents (if any) of the asset to their pre-exposure state Services Repair Cost: Costs incurred in returning the services (if any) of the asset to their pre-exposure state Plant Repair Cost: Costs incurred in returning the plant (if any) of the asset to their pre-exposure state Stock Replacement Cost: Costs incurred in returning the stock (if any) held at the asset to their pre-exposure state Cleanup Cost: Costs incurred for necessary demolition, and/or removing debris, silt, effluent etc. from an asset Disruption Cost: Costs incurred due to the disruption of activities usually conducted in the asset Vehicle Cost: Costs incurred due to the damage of vehicles located at the asset | • Buildings • Electricity cables • Network junction point • Pipelines • Roads • Telecommunication cables • Waterways |
