Geographic information systems: a consistent approach to land use planning decision around hazardous installations

摘要

The Health and Safety executive (HSE) advises Local Planning Authorities abut the siting of major hazard installation and pipelines and the control of housing and other developments nearby. HSE uses quantified risk assessment (QRA) to set a consultation distance around each of the major hazards and advises on possible risks to people within this distance so these risks can be considered in reaching planning decisions. The risks may be derived from dispersion models which estimate concentration levels and exposure times for a range of loss of containment accidents.
