In the petrochemical industries, regular annual repair and maintenance work (including overhaul) presents risks higher than generally found in normal operation. It therefore requires a greater amount of labor. Because common petrochemical business operations are rarely routine, it is commonly necessary to outsource this work and hire massive numbers of additional staff in a short time lessen costs. Because these laborers are not usually familiar with the system's regulations and use, the present paper has taken a set of safety rules, and health education and training patterns as a goal for research. Provides contracts business duty disaster to prevent the countermeasure. It is importance that it cuts the duty disaster formation rate. This will certainly be helpful to practical petrochemical industrial operations.
