安全措施，預防發生意外事故。從業員需留意以下的安全措施：
1. Prior to the commencement of fabrication, site foremen, engineers and relevant parties
should jointly carry out a risk assessment of the reinforcement cage fabrication process and
implement the safety measures determined as a result of the assessment.
2. A method statement for the fabrication of reinforcement cages should then be drawn up, 1. 在開始扎籠之前，地盤主管、工程師及其他相關人士應參與扎结鐵籠風險評估
including the relevant risk assessment, working drawings, safety working procedures, etc. ，並按扎籠風險評估的结果，採取相關的安全措施。
3. For the fabrication work, suitable equipment including arc-shaped fabrication frames, 2. 應制訂可行及安全的扎结鐵籠施工方案, 包括風險評估、施工圖及步驟等。
ground plates, working platform, etc, should be used. 3. 在扎籠過程中，需使用合適工具包括弧形結構支架底座、地台板及工作台等。
4. The arc-shape fabrication frames and ground plates should be placed on rigid and flat
ground. Barriers and warning signs should be provided to guard against possible damage 4. 鐵籠的弧形结構支架及地台板應設置在平坦及堅固的地面上，並放置圍欄及警
