Consequence analysis is carried on to evaluate the extent of the possible consequences associated to a top-event and it is usually an integral part of a safety review (or QRA or PHA).
The consequences related to a plant top-event are usually assessed in the QRA or PHA of a plant. Please refer to Plant Safety for further details.
At the site level, the consequences are modelled in relation to Site-wide top-events as highlighted in the Industrial safety top-events identification, HazOp, QRA/PHA pages, some types of top-events are better suited to be studied at a site level and Eidos has developed specific methods for these top-events:
- Production of missiles made of ductile material due to explosions and their effects on people, buildings and equipments when the source and the target are different plants
- Production of debris made of brittle material due to explosions and their effects on people, buildings and equipments when the source and the target are different plants
- Consequences coming from seismic waves (screening method developed with Politecnico di Torino University)
- Consequences of spills of dangerous substances on groundwaters. In this case the target is not a plant
- Effects on buildings from explosion blasts when the explosion source is located in a different plant or the buildings are not related to the plants (management offices, IT offices and so on)
- Domino effects arising from heat radiations, explosion blasts and missile productions when the source and the target are different plants or the targets are not related to any plant). Eidos has developed two different sets of model for screening or detailed evaluation
Eidos is licensed to DNV Phast Multicomponent with the new radiation shielding extension.
Eidos employs skilled personnel on GIS (ArcInfo) and CAD (Autodesk) to produce consequence plots.
In last years Google Earth is becoming more and more popular. This, and the fact that is free, leads the Authorities to ask for Consequences representation to be supplied in kmz format (the native format of Google Earth application). Eidos extended its knowledge on GIS/CAD to include the capability of preparing kmz consequences representations fully geo-referenced and in 3D. Please refer to Plant safety for some samples.
