A Fundamental Study on Easy-to -Understand Work Procedure Manuals for Safety Work in Construction Sites

This study focuses on work procedure manuals used on construction sites and aims to obtain basic findings related to work procedure manuals that are easy-to-understand for workers, including younger workers. Specifically, work procedure manuals in actual construction sites were analyzed from the perspective of 5W1H, and identified problems through improvement review meetings which included experts of occupational safety. Then, new work procedure manuals for resolving these problems were devised, and also some video-based prototypes which effectively showed the work procedure manuals to workers were created. Furthermore, the proposed work procedure manuals and the video-based prototypes were evaluated by a practitioner in an actual construction site. As the results, it is shown that the proposed work procedure was evaluated overall as easy-to-understand for new workers, although some aspects needed improvement. From the above, we clarified the requirements of work procedure manuals that are easily understandable for new workers.
