As a Development of Industrial process, human, environment,

equipment, material and validity of system has been exposed to hazardous conditions. Regards of

32.3 percent of occupations in industries, this study focused on risk assessment of foundry unit by

energy trace and barrier analysis (ETBA) method and presented approaches to control of accident.


the recent study is as a case study one to risk assessment in a foundry unit in Qazvin

industrial city in1387. In this study risks were founded by ETBA method and evaluated by MILSTD-
