IIT-QRA Model for Airborne Accidental Release of Hazardous Chemicals

Introduction

The IIT-QRA model, a modified form of IIT Heavy Gas Model, can be used to carry out quantitative risk assessment (QRA) related to the accidental release of denser - than-air vapour clouds. Further QRA results can be utilized for demarcating the zones of influence and areas of potential risk on the basis of their risk levels. To fulfill this air, appropriate probit equations and other necessary parameters like population density, equipment failure frequency, etc have been incorporated in the IIT Heavy Gas Model.

Salient features:

The IIT-QRA model has been validated by comparing its risk estimates with those given by RISKAT - model and MAXCRED model. The performance of the model has been found satisfactory for the purpose of quantitative risk assessment (QRA) pertaining to air-borne accidental releases of extremely hazardous substances such as chlorine.

Prospective Users: Chemical and Petro-chemical industries.
