EXECUTIVE SUMMARY WIRE Consultants has been engaged by Punjab Chemicals & Crop Protection Ltd. for the Quantitative Risk Assessment (QRA) of their process plant at their facility in Lalru, Punjab. Present report is the Quantitative Risk Assessment Report for the process plant based on the data and inputs provided by the PCCPL Team. The site visit was carried out at Punjab Chemicals & Crop Protection Ltd., Lalru on 15th, by multi- disciplinary team personnel from PCCPL and Wire Consultants. The area in Scope of the Study is “Storage Area of Lalru Facility”. The Vapor Cloud Explosion scenarios were not credible because the area is open and highly ventilated and hence the software couldn’t generate the results for the same. Failure frequency rates were taken from the OGP Guidelines. The cumulative IRPA value for the site is 1.79E-05 per year and lies on the threshold of low-risk region and ALARP risk region. The societal risk lies largely in ALARP region. All the results and distance of the Heat Radiations from Jet Fire and Flash Fire, Toxic Gas Envelopes and 3D Contours are attached in the Annexures of the Report and FN Curve generated are provided in the “Results and Observation” Section. 4 REV 1 PUNJAB CHEMICALS & CROP PROTECTION LTD 3D QRA LALRU 19/02/2020 3. INTRODUCTION The Client is one of the biggest Industries in India dealing with manufacturing and sales of specialty and other chemicals. This report details the Scope of the study, Results & Observations of the Assessment. This report has been supplied in a digital format, and therefore the copy archived at WIRE server shall be considered as the primary document. This report and related files submitted should be considered as secondary documents. 3.1 FLUID PROPERTIES The basic physical &chemical properties of the materials are given in the below table with reference to the MSDS.
