Abstract

Workplace accidents are common while working at elevations. Thus, various safety measures such as safety handrails and horizontal safety nets are implemented to prevent falls. The minimum safety measure is the lifeline installation. However, because its standards have not been clearly established, it is often misused, resulting in inappropriate knot methods that increase the chance of accidents while working at elevations. Therefore, clarifying the appropriate usage methods or criteria for the various lifelines is required in the field. This study proposed an appropriate installation method by experimentally and numerically evaluating the change in strength according to the fixed knot lifeline method. In addition, three knot methods were specified for each material. The results obtained are expected to contribute to lessening falls through the establishment of lifeline installation standards and the development of appropriate parts.
