When safety belt is used, hook is hanged at higher place and people operates at lower place. Each operator at high place must have the falling protec

38、tor. 在高处使用撬杠时，人要立稳，如附近有脚手架或已安装好的构件，应一手扶住，一手操作。撬杠插进深度要适宜，如果撬杠距离较大，则应逐步撬动，不宜急于求成。While using crowbar at high places, people shall stand steadily. If there is any scaffold or installed members, the staff shall hold it and operate by one hand. Inserting depth of crowbar shall be proper. If crowbar dista

39、nce is larger, slow crowing shall be taken. 雨天进行高处作业时，必须采取可靠的防滑措施。作业处和构件上有水、应及时清除。遇有六级以上强风、暴雨等恶劣气候，不得从事露天高处吊装作业。暴风雪及暴雨后，应对高处作业安全设施逐一加以检查，发现有松动、变形、损坏或脱落等现象，应立即修理完善。In case of working at height in rainy days, reliable anti-sliding measures shall be taken. Water on operating place and members shall be

40、cleaned in time. Under the circumstance of over 6-grade wind or storm, any lifting at high place in an open air is not allowed. After the storm passes, safety facilities for work at height shall be checked one by one. Maintenance and improvement shall be made if there is any loose, deformation, dama
