Fire and explosion both have become most repeatedly occurring disasters in India, which requires more attention, and strict compliance of regulatory authority to mitigate its consequence. The origin of fire hazards in now a day is closely related to the Industrial Rebellion. The frequent happening of fire and explosion hazards has become an area of concern for both the settled and developed nations. Since May 2020, there have been 30 industrial accidents have been reported in India, killing minimum 75 workers. From 2014 to 2017, within three year approximately 8,004 number of such incidents occurred in Indian workplaces killing 6,368 industrial employees in which fire and explosion is one of the major contributor. Fire in storage tanks containing flammable liquid have been increased drastically within three year due to inadequate over flow arrangement, failure to provide safety devices, poor maintenance of control equipment and instrument, loss of primary containment system, and integrity failure of secondary containment system etc. A systematic analytical approach has been determined to identify fire an explosion n risk for one of the biggest storage facility which stored Iso propyl alcohol. A theoretical dispersion modelling study has been performed to identify fire and explosion risk. The dispersion study is used to estimate or to predict the downwind concentration of environment pollutants such as flammable gas or any other gas which is in hazardous nature emitted from the sources such as storage tank or industrial plants or process vessel/ pipeline etc. In the atmosphere, dispersion depends upon the types and numbers of sources, various meteorological factors and topography of the terrain. The main advantages of this dissertation is to provide overall worst case predictable consequence when a chemical release from the storage how far it can be impacted to the surrounding area, plant, machinery, equipment or community. This study will not only gives the resultant perimeter of consequence modelling even although predicts the control measure to bring down the fire an explosion risk in acceptable manner where minimum impacted can be levied as a residual risk.
