Evaluation of Hazard and Minimization of Risk of Nitroglycerin in Pharma Industry using ALOHA & Event Tree Analysis

As we all know chemicals are highly hazardous and toxic in nature. They are hazardous till the stage of manufacturing to the stage of storage. This is a study which has been carried out in a pharma industry where the workers are exposed to Explosive and hazardous chemicals such as Nitroglycerin, Chlorine dioxide, Hydrogen peroxide, Methanol and other like these. In this research physical and chemical properties of chosen chemicals are studied. In the second step we have done checklist analysis where the needed data is collected which is going to be used for further steps.in the next step we have to select a highly hazardous or toxic chemical, Toxicity Calculation and hazardous risk is used to rank the chemicals based on the data gathered from checklist. After these selections are made for highly hazardous or toxic chemical, the next step is to find out what are the consequences and risk we are going to face if there is an accident or release of these toxic chemicals in environment. For this, Event Tree Analysis (ETA) is used in next step. In the next step we have to calculate the risk from ETA and find that how it is dispersed into atmosphere and till how much distance it's going to affect. In the next step we are to calculate human health and safety loss, using the distance found out by software and compensation amount collected from laws. In the final step we will make the precautionary & preventive measures to avoid the toxicity dispersion of chemicals in atmosphere with emergency preparedness in case of chemical release by any means.
