Evaluation of Hazard and Assessment of Toxicity Index of Potassium Fluoride in Warehouses using Aloha and Rectification by Safety Information System

Chemical industries can be highly dangerous for human kind as well nature.in the different stages of manufacturing different types of chemicals are used out of which some are toxic and some are non-toxic. Storage of toxic chemicals can be a risky task. This research has been done in a fluoro chemicals industry where many toxic chemical like potassium fluoride, Ammonium difluoride, Potassium fluoride, Sodium fluoride, Potassium fluoro titanate, Potassium fluoroborate and Hexafluorophosphoric acid are used and produced. By using Aloha method event tree analysis we have identified the hazard related to the leak of hazardous chemical. Next toxicity Index Calculation is used to rank the chemicals based on the data collected from checklist. After the selection of the hazardous chemical, the next step is to find out what is the next event going to happen if there is a release. For which, Event Tree Analysis (ETA) is used in this step. The next step after finding the final event from ETA is to find how it is dispersed into atmosphere and how much distance it covered if any leak happened. It can be easily found out using the ALOHA Dispersion Software. The next step is human health and safety loss calculation using the distance found out by software and compensation amount gathered from law. The final step is to make the precautionary & preventive measures to avoid the toxic dispersion into atmosphere and the emergency preparedness should be prepared for what should be done during the toxic release, we have reduced the risk by using safety information system.
