선행난간 시스템 비계의 설치작업 위험성평가에 대한 연구

초록

Approximately 50% (485 people) of fatal accidents occurred in domestic industrial sites, and 59.8% (290) of them were caused by falls. In the last three years, 99 fall fatalities occurred in steel pipe scaffolding and system scaffolding, of which five occurred in system scaffolding. The installation of a system scaffolding horizontal member is called a trailing railing. Workers climb on the working platform without guardrails, transport materials, and install horizontal members. Because the guardrails are not installed, the worker is exposed to a risk of falling. Even if it is a system scaffold, falls do occur. The government provides funding for small-scale construction projects that install system scaffolding, which has a lower risk of falls than steel pipe scaffolding. A risk assessment was conducted and compared when installing the conventional guardrail and the advanced guardrails to confirm the likelihood of fatalities, such as falling. The results of this study designate a target for clean project support for spreading and expanding the market of advanced guardrail system scaffolding. They recommend the revision of related laws for legal and institutional supplementation of the conventional guardrail, and mandatory use for construction ordered by the government, public enterprises, and public institutions.
