Abstract: Hazard Operability (HAZOP) study is especially valuable for recognizing shortcomings in frameworks (existing or proposed) including the stream of materials, individuals or information, or various occasions or exercises in an arranged grouping or the methodology controlling such a succession. The HAZOP study was carried out in one of the fertiliser industries in India. The investigation was done for five unique tasks having 17 hubs, unusual working conditions and bothersome exercises which may happen are recognized and considered amid the examination utilizing suitable guide words like No, More, Less, As well as and so on. More stream, more temperature, more weight and additionally in the hubs are having unfavourable impact and prompt consideration is required. 101 reasons for deviation were distinguished. The causes are as given: disappointments in the dimension estimation instrument, non direction of the siphon, execution of creation process physically, erosion of the caustic way, obstruction of the passages, blemished check valves, mechanical issues of check valves, spillage of the channels, and blending of water in the framework. 35.7 % of all dangers were inadmissible, 37% risky, 19.8 % satisfactory yet required re examination, and 7.5% worthy with no requirement for any restorative activity. To keep any calamitous results, we prescribe to do HAZOP think about.
