According to this study, small-scale construction projects with a construction value of less than 300 million won are placed in the blind spot of safety management inspection. Therefore, it is necessary to improve the management and inspection system that reflects characteristics of small-scale construction sites.

This study suggested the improved safety certification marking system on the types of the temporary equipment. By surveying and interviewing the related persons in the construction company, the manufacturing company, and the rental company, the safety certification marking system was analyzed. The results show that the efficient marking was analyzed to utilize a depressed engraving on the target equipment and material. For marked contents, a certification mark, an identification number, and the production year should be displayed and the manufacturer name could be selectively presented. However, the opinions of the certification mark position among the users and manufacturers did not come into the agreement.
