水平安全母索於建築工程使用之安全管理問題探討

Discussion on Safety Management of Horizonal Lifeline used in Construction Engineering

營造工程大多為高處作業，作業中因水平安全母索設置缺失，施工人員作業中未確實將安全帶勾掛於水平安全母索，都是造成墜落的主要原因。實務調查國內建築工程水平安全母索使用缺失如下：1.水平安全母索設置欠缺整體安全系統設計考量；2.管理者對於水平安全母索材質強度選用錯誤；3.水平安全母索設置未具連貫性；4.錨錠端點固定方式錯誤造成強度不足等。因此，為避免勞工於高處作業發生墜落意外，對水平安全母索設置建議如下：1.從設計者角度就水平安全母索的安全性於法規面進行檢核。2.設計單位應就水平安全母索設置費用納入契約編列。3.對水平安全母索選用與適用時機，應考量材質變異及其繫結強度與連貫性要求。4.依法規要求，鋼構屋頂邊緣及屋突出頂板應設計適當強度欄杆。此外，5.將水平安全母索安裝設置納入簽證制度，以確保其功能的安全性。

Construction activity are mostly dangerous work when people who working at high place, the luck of facilities of horizontal lifeline setting and the worker not used safety belt correctly etc., these are the reason for falling. According to the practical survey of the horizonal lifeline wrong usage situation in the construction site are, 1) the setting of horizonal lifeline is lack all systems of safety design consideration; 2) the manager wrong choice for the material of strength by the horizonal lifeline types; 3) horizontal lifeline setting was not consistent; 4) incorrectly of anchor point fixed resulting in insufficient strength etc. Therefore, in order to avoid workers working at heights place occurs falling accidents, the suggestions for setting the horizontal lifeline are as follows: 1) from designer's viewpoint to check the regulatory requirements; 2) the design unit should include the installation cost of the horizonal lifeline into the contract; 3) for the selection and application of horizontal lifeline setting need to inspect the requirements of material variation strength and consistency; 4) according to the requirements of laws and regulations, the roof slab protruding from the edge shall be provided with railings of appropriate strength. And 5) the installation settings of the horizontal lifeline shall be included in the endorsement system to ensure the safety of its functions.
