Reliability and validity of organizational factors measurement in risk management of process industry equipment

Abstract

In recent decades, process safety control and process safety risk assessment have become very attractive topics. The way control is carried out, using tools such as HAZOP, FMEA, FTA, and similar is not sufficient to adequately prevent or control accidents with serious consequences in the process industry. The need to analyze the causes of the causes themselves, with special emphasis on the impact of organizational factors has arisen. This research results in the development of an original, reliable, and valid measuring instrument for assessing organizational factors important for risk assessment methodologies in working with pressure equipment. The initial instrument was designed based on the previous research and then checked by statistical analysis, using the Kaiser-Meyerto-Olkin test, exploratory factor, and reliability analysis. The proposed instrument has reduced 71 to 48 dimensions, describing 10 organizational factors important for risk management of pressure equipment. Providing a valid and reliable measurement instrument is essential for a proactive approach, which enables managers employed in the organization to mitigate the risks of pressure equipment operation, and prevent accidents. The proposal of further research is the application of confirmatory factor analysis or/and structural equation modeling on data collected.
