HAZARD ANALYSIS AND RISK ASSESSMENT IN THERMAL POWER PLANT

This project deals with various types of hazard analysis and finding a risk assessment in thermal power plant. The safe working operation of a thermal plant needs to identify the hazards, assess the associated risks and bring the risks to tolerable level on a continuous basis. There are several unsafe conditions and practices in various process and equipments of the thermal power plant lead to a number of accidents and which can causes loss and injury to human lives, damages the property, interrupt production etc. A risk assessment is an important step in protecting the plant from such conditions. It helps us to focus on the risks that really have the potential to cause harm. The hazard resolution process is to assess the identified hazards in terms of the severity or consequence of the hazard and the probability of occurrence of each type of hazard. Risk classification by severity and probability can be performed by using a risk assessment matrix. This assessment allows one to assign a risk assessment value to a hazard based on its severity and its probability. This value is then often used to rank different hazards as to their associated risks. To determine what actions to take to eliminate or control identified hazards, a system of determining the level risk involved must be developed. A good mishap risk assessment tool will enable decision makers to properly understand the level of risk involved, relative to what it will cost in schedule and dollars to reduce that risk to an acceptable level. Risk determination is an essential and systematic process for assessing the impact, occurrence and the consequences of human activities on systems with hazardous characteristics
