Hazard assessment of hot water boiler at thermal power plant

Our world and every person require a huge amount of energy, both electric thermal, which are produced mainly at various types power plants, but mostly on thermal. During the production electricity heat thermal plants different potential hazards occurring: chemical, environmental, fire or explosion. In accordance with identified possible six emergency situation scenarios suggested. The failure tree method was used for determining danger hot water boiler being one elements plant. Given conditional probabilities events, it is obtained that possible. For reducing probability improving safety – barriers (functional symbolic) proposed. After inserted, in our case almost incredible. Many people live near may have risk harm to their health. An approach indicator health (R) It provides division levels into four classes: extremely high degree hazard R>0.1; 0.1>R>0.001; average 10 −3 >R>10 −5 ; low R>10 .
