Risk assessment and management techniques are used in industrial activities to reduce accidents by applying preventive and protective methods. In this article a preventive approach called Hazard and Operability Study (HAZOP) and Hazard Identification (HAZID) was used. The application of HAZOP, a process hazard identification and control method, has been demonstrated in the Effluent Treatment Plant (ETP).

The aim of the HAZID is to provide input to the subsequent risk analysis to be conducted as part of the Environment, Health & Safety at Effluent Treatment Plant (ETP). The HAZID session is a small contribution to the overall aim of the project, through being the initial step in the safety analysis. The value added of the HAZID work (Step 1) is that it facilitates a more focused risk analysis (Step 2) through providing an understanding of the existing hazards. The HAZID report also provides a valuable input to the risk-based design process to be conducted in Effluent Treatment Plant (ETP). Recommendations are made on the basis of the findings to improve the installation and make it better and more safe place to work. Attempt has been made to carry out HAZID and HAZOP study thoroughly through the Effluent Treatment Plant (ETP) and recommendations were given to make the plant more safe place to work.
