In chemical plants that handle toxic and hazardous materials under various operating conditions, Toxic and hazardous materials are highly likely to cause serious industrial accidents, such as fires, explosions, and toxic material leaks. In order to prevent serious industrial accidents, it is necessary to systematically analyze the large and small accidents that have occurred and find the root cause to prevent serious industrial accidents.
Currently, under Articles 54, 55, 57, and 73 of the Enforcement Rules of the Industrial Safety and Health Act, all employers are obliged to report and investigate the cause of accidents and plan to prevent recurrence. The disaster investigation table in attached Form 30 of the Enforcement Rules is not enough to prevent serious industrial accidents by analyzing the cause of accidents and establishing measures to prevent recurrence of accidents due to unclear analysis method and guidance. Therefore, many companies have established measures to analyze causes and prevent recurrence through several accident cause analysis techniques.
These day, many Korean companies use simple techniques such as 4M (Man, Machine, Method, Material), and 5-Why, and large and global companies use techniques such as Taproot, Systematic Cause Analysis Technology (SCAT) and Apollo to analyze the root cause.
This study look into the functions of various root cause techniques, and found that most fundamental cause analysis techniques focused on the consequence of accidents. Therefore, it is lacked education to prevent recurrence of accidents due to poor cause and consequence relationship. I proposed a new method of combining the Bow-Tie technique, which is a risk assessment technique, and the 5 why cause analysis technique, so that the relationship between the cause and consequence of the accident can be easily identified through new technique.
