  • Emergency Planning and the control of major accident hazards comah seveso ii directive an approach to determine the public safety zone for toxic cloud releases
    Journal of Hazardous Materials, 2008
    Co-Authors: Mary T Omahony, Donal Doolan, Alice Osullivan, Michael Hession
    Abstract:

    The EU Control of Major Accidents Hazards Directive (Seveso II) requires an external Emergency plan for each top tier site. This paper sets out a method to build the protection of public health into Emergency Planning for Seveso sites in the EU. The method involves the review of Seveso site details prescribed under the directive. The site safety report sets out the potential accident scenarios. The safety report's worst-case scenario, and chemical involved, is used as the basis for the external Emergency plan. A decision was needed on the appropriate threshold value to use as the level of concern to protect public health. The definitions of the regulatory standards (air quality standards and occupational standards) in use were studied, how they are derived and for what purpose. The 10 min acute exposure guideline level (AEGL) for a chemical is recommended as the threshold value to inform decisions taken to protect public health from toxic cloud releases. The area delimited by AEGL 1 defines the population who may be concerned about being exposed. They need information based on comprehensive risk assessment. The area delimited by AEGL 2 defines the population for long-term surveillance when indicated and may include first responders. The area delimited by AEGL 3 defines the population who may present acutely to the medical services. It ensures that the Emergency responders site themselves safely. A standard methodology facilitates discussions with plant operators and concerned public. Examples show how the methodology can be adapted to suit explosive risk and response to fire.

  • the use of geographic information systems in major accident risk assessment and management
    Journal of Hazardous Materials, 2000
    Co-Authors: Sergio Contini, Michalis D Christou, Furio Bellezza, Christian Kirchsteiger
    Abstract:

    Abstract The paper discusses the use of modern information technologies, and in particular geographic information systems (GIS), in the management and control of major accident risk. For this purpose, the regulatory framework of the recent “Seveso II” Directive is briefly described. This asks for more transparent procedures and decision-making, and requires consultation of the public in land-use and off-site Emergency Planning. Correspondingly, new demands are put to support tools being developed. The main features of tools dealing with hazard sources mapping, risk assessment, risk management, and Emergency Planning are discussed and examples are given. Moreover, it is argued that, if appropriately designed, their use can enhance the dialog between plant operators, authorities and the public to facilitate a consensus on risk issues. Finally, limitations in the use of these tools and prospects for future developments are discussed.
