Risk Management Information System A Spatial Planning Tool

Risk Management Information System A Spatial Planning Tool for Chemical Disaster Management International Conference on Environmental Knowledge for Disaster Risk Reduction Vigyan Bhavan, New Delhi May 10, 2011 SENES Consultants India

The Concern • The worst industrial accident occurred in Bhopal in December 1984; • Exposure to Methyl Isocyanate (MIC) leaking Carbide from Plant Union caused significant number of deaths and injuries; • World wide rethink on chemical Iconic photograph titled “Burial of an unknown child” -by Raghu Rai, Bhopal 1984

The Concern • No information available from Union Carbide on the nature of hazards present within premises; • People unaware on how to react to be able to minimize exposure to MIC; • Hospitals & medical professionals did not know what gas was released and how to treat victims; • There was no immediate notification of the accident to the Administration; • There was no Emergency Response Plan & the Administration could not respond to accident on time;

Presentation Flow • Key issues in managing chemical risk; • Need for GIS-enabled integrated information systems and modelling tools; • The Risk Management Information System (RMIS);

The Issues • Technological risk events typically unfold in matter of hours – short response time • Requires updated information from diverse sources to assess damage • Prediction needs solving of complex algorithms and

Why we require information system support? • Management of a chemical risk scenario is information intensive; • Models require high processing power; • Strong spatial dimension;

Gaps in existing tools • Provide end point effect distances for different incidents; • Hazard displayed footprints for better visualization; • Risk maps shown as contours; • But, not closely coupled ALOHA /MARPLOT ARIPAR EFFECTS

Risk Management Information System (RMIS) Key Features: • Aggregate information on industries, chemicals, hazards, vulnerability, emergency responders in a single database; • Provides for spatial analysis and better understanding of chemical risks; • Transparent mechanism for sharing risk related information; • Integrated with QRA based consequence analysis

RMIS – Key Benefits • High scale of Maps – better representation of hazards and vulnerabilities; • Hazard Data and Maps can be updated / managed in a distributed manner or centrally; • [ Active ] Modeling of accident scenarios – MCLS or any quantity of chemical; • Live Meteorology Information while the risk event is unfolding;

Building the RMIS • Industrial town of Haldia in West Bengal; • Identifying and mapping chemical hazards; • Mapping elements at risk; • Appending information in a central database; • Integrating Risk Analysis Models for prediction of accident scenarios;
