侷限空間Confined space
Confined spaces present high levels of risk for workers. A tripod (EN795) with a lifting device EN1496 must be used so that a worker can be quickly rescued in the event of an accident. A secondary safety rope with an auto-locking descender is required (fig. 12).侷限空間比高空作業帶給工人更高的風險。用一個三角架(Tripod, EN795認證)作為固定點,具備鋼索捲揚器(EN1496認證),以備工人在發生意外時可以快速的將他救上地面。必需架設另一條安全繩(靜力繩,EN1891)通過一個自動制停的確保器,由地面上一位確保員收放繩索,以防止工人墜落。
