Consequence Analysis, Vulnerability Mapping and Fuzzy Fault Tree Analysis for a Better Disaster Management in and Around Chemical Industrial Areas

V. R. Renjith, G. Madhu

Abstract


Chemical industries are prone to hazards like fire, explosion and toxic gas releases. Qualitative and quantitative hazard analyses are essential for the identification and quantification of the hazards associated with chemical industries. This study presents the results of a consequence analysis carried out to assess the damage potential of the hazardous material storages in an industrial area of central Kerala, India.  These results are used for the estimation of individual risk and societal risk in the above industrial area. Vulnerability assessment is carried out using probit functions for toxic, thermal and pressure loads. Results of fuzzy Fault Tree Analysis (FTA) and Two dimensional fuzzy FTA (TDFFTA) are also discussed.
