بررسی پایایی و روایی پرسشنامه فرهنگ ایمنی

  Background and aims   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.     Methods   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- 882B. Data were collected by direct observations, interview with workers and supervisor and engineers, walking-talking through method, documents investigation of operational processors, preventive maintenances, equipment technical properties, accidental and medical documents. Finally ETBA worksheets completed.     Results   totally 154 risks has been found. 40 from total are been unacceptable risk, 68 unfavorable and also 46 acceptable but with remediation action. Casting workshop had risks more than other workshops (with 74 identified risks).Potential and heat energies were founded as most   hazardous energies, with respectively 51 and 38 risk cases.     Conclusion   This study recommended to be done actions for identification and control risk, such as: safety training, occupation training, preventive maintenance, contract safety, safety  communication and safety audit group.
