Operators should take the initiative to avoid hanging objects and enhance their safety awareness of self-protection and mutual protection.

4． Formwork support should be carried out according to the prescribed operating procedures, and the next process should not be carried out before the formwork is fixed. It is strictly prohibited to climb up or down on connections and supports.

5. When setting up the formwork, the operator must not stand on the support, but a manboard should be set up to facilitate the operator to stand. It is advisable to use a wooden mid-board for the standing board, and it should be properly tied and fixed. Steel formwork or 5cm x 10cm wooden boards are not allowed.

6. During the formwork process, if there is a need to stop midway, the supports, headers, capital plates, etc. should be nailed firmly. During the interval between formwork disassembly, the moved formwork, pull bars, supports, etc. should be transported away or properly stacked to prevent them from falling due to stepping on or supporting the air. If there are reserved holes on the formwork, the holes should be covered after installation. For reserved holes on the concrete slab, the holes should be covered immediately after the formwork is removed.

For collapsible loess, waterproofing measures must be taken; for frost-heaving soil, anti-freezing and thawing measures must be taken.

8． During the installation process of the formwork and its brackets, temporary fixing facilities must be installed to prevent overturning.

9． The two people must cooperate with each other and work together when lifting the template. The transfer templates and tools should be fastened with rigging and transported by vertical lifting machinery. They must not be thrown around. When the combined steel formwork is being assembled and disassembled, there should be someone at the top and bottom to help.

10． When constructing on the formwork, there should not be too many piles of objects (steel formwork, etc.) and they should not be concentrated in one place.

11． During the construction of large formwork, anti-overturning measures must be taken to store the large formwork. When sealing the column formwork, it is not allowed to cover it from the top down.
