In case of gale of magnitude 6 or above, fog, rain and snow, scaffold operation should be stopped. Anti-skid measures should be taken for shelf work after rain and snow, and snow should be removed. It is forbidden to engage in the erection and removal of scaffolding during the process of ship shifting, launching and docking. When the 3.2.5.5 or the vertical structure is in a moving and unstable state. In 3.2.5.6, in principle, the erection (demolition) of large-area and waterfront scaffolding is not arranged at night. 3.3 Inspection and Acceptance of Scaffolding 3.3. 1 In the process of scaffold erection, the scaffold construction unit shall have a special person responsible for site management. After completion, the installation quality shall be checked item by item according to Scaffolding Quality Inspection Table (GL/CH04-006-R-0 1). If it does not meet the requirements for safe use, it shall be rectified immediately. Those that meet the inspection requirements shall be inspected by the service workshop operator. 3.3.2 The operator of the maintenance workshop shall inspect and accept the completed scaffold according to the scaffold quality checklist (GL/CH04-006-R-0 1). If the first inspection fails, the reasons for the failure shall be explained in the comments column, and the construction unit shall be ordered to make rectification, and the second inspection shall be conducted after rectification. If the second inspection still fails to meet the requirements for safe use, the operation shall be suspended and reported to the workshop leader to adjust the construction team, and the relevant personnel shall be assessed for responsibility system. Scaffolds that are seriously unqualified should be rebuilt. 3.3.3 The engineering supervisor of the user department is responsible for organizing the scaffold applicability inspection. If the first inspection fails, the reasons for the failure shall be explained in the comments column, and the service workshop and the construction unit shall be required to make rectification, and the second inspection shall be conducted after rectification.

The people who pass the materials in 3.6.2.3 below should stand in the wrong position with the people who dismantle the frame above. When transferring materials, the pace should be consistent and the construction personnel should maintain a high degree of coordination. It is forbidden to change people in the process of demolition in 3.6.2.4. If there must be a replacement, the demolition situation should be explained clearly. When the steel mesh is dismantled in 3.6.2.5 cabin, the steel mesh plates should be neatly stacked on the support and tied with two ropes. Dismantled steel pipes shall be neatly stacked on the steel pipe bracket at one end, and no fasteners shall be entrained. After the steel pipe is full, both ends should be locked with cross bars and fasteners, and the removed fasteners should be placed in the fastener barrel. All dismantled materials shall be stacked in order in the cabin and hoisted out in time. It is forbidden to mix steel pipes and fasteners. Dismantling the closed cabin in 3.6.2.6 should be carried out in the reverse order of installation. When the demolished materials are handed out of the hatch by people, the upper and lower construction personnel should maintain a high degree of cooperation. When pulling the materials to be dismantled out of the hatch with ropes, the ropes binding the materials must be made twice, and the distance between the two ropes should not be less than1m. In principle, 1 piece of material should be pulled out from the hatch every time. It is forbidden to pull two pieces of materials with too long length out of the hatch together, and the upper and lower construction personnel should maintain a high degree of cooperation. 3.6.3 Safety requirements after dismantling 3.6.3. 1 Materials dismantled from the closed cabin shall be neatly stacked on the deck, and it is forbidden to block the safe passage. Dismantled scaffold boards should be neatly stacked according to specifications, tied with two ropes, and steel pipes and fasteners should be operated according to the above requirements.
