Power plants are potentially high-risk facilities since the consequences of a severe accident at a power plant can be enormous. Severe accidents of power plants affect a large area and have an environmentally regional and economically global character. The most common hazards to power plant workers are electrical shocks and burns, boiler fires and explosionsand contact with hazardous chemicals.

The identification of hazards, the evaluation of related risks, and the continuing reduction of risks to manageable levels are all-necessary for the safe operation of a power plant.

Risk management is a crucial step in securing the power plant against such threats. The incidence of failure and the resultant effect are constantly associated with risk. It is essential to predict such circumstances and assess risk to take appropriate preventative measures.
