Safety protection measures for high-altitude scaffolding operations: 1. Personnel erecting or dismantling scaffolding must comply with the "Regulations on the Administration of Safety Technical Training and Assessment for Special Operators" issued by the Ministry of Labor. After passing the assessment, they must obtain the "Operation Certificate for Special Operators" 》Professional scaffolding work. 2. Operators should be certified to work. You must wear a safety helmet, safety belt, and non-slip shoes during operation. 3. In heavy fog, rain, snow, and strong winds above level 6, no high-altitude operations on scaffolding are allowed. When working after rain or snow, safety and anti-slip measures must be taken. 4. When erecting scaffolding, it should be erected row by row, span by span and step by step according to the requirements of forming the basic structural unit. Rectangular peripheral scaffolding should be erected starting from one corner and extending in two directions. Make sure the installed part is stable. For portal scaffolding and other scaffolds with poor longitudinal vertical surface stiffness, it is advisable to add long longitudinal horizontal bars to connect with connectors at the wall connection point. 5. During erection operations, self-protection and the safety of personnel at the work site should be protected according to the following requirements: (1) Workers working on the erection should wear non-slip shoes and safety belts. To ensure the safety of the operation, the necessary number of scaffolding boards should be laid under the feet, and they should be laid smoothly, and there should be no probe boards. When it is temporarily impossible to lay footboards, the rods used for footing, grasping, and holding (clamping) should be stable part of the frame. The horizontal distance between the focus point and the frame node should not be greater than 08m, and the vertical distance should not be greater than 15m. . Free poles located above pole joints (those not yet connected to horizontal poles) shall not be used as holding poles. (2) The workers on the rack should have a good division of labor and cooperation, and the transfer rods should grasp the center of gravity and transfer smoothly. Do not use excessive force to avoid imbalance of your body or the pole. For each completed process, they must ask each other and confirm before proceeding to the next process. (3) Operators should wear tool bags. Put tools in the bags after use and do not put them on shelves to avoid falling and injuring people. (4) Erection materials should be readily available to prevent them from falling when placed improperly. (5) Before each completion of work, all shelving materials should be erected and should not be left on the shelves, and a stable structure must be formed. The parts that cannot form a stable structure should be reinforced with temporary bracing measures. (6) During the erection operation, cooperating personnel on the ground should avoid areas where objects may fall. 6. Safety precautions when working on racks: (1) Before operation, you should check whether the working environment is reliable and whether the safety protection facilities are complete and effective. Operation can only be carried out after confirmation. (2) When working, you should pay attention to clearing the materials dropped on the shelves at all times, keeping the shelves neat and clean, and do not place materials and tools randomly to avoid affecting the safety of the operation and causing injuries to people due to falling objects. (3) When prying, pulling, pushing, etc., be careful to adopt the correct posture, stand firm on your feet, or hold on to a stable structure or support with one hand, so as not to use excessive force and lose your balance or throw things out. When removing the formwork from the scaffolding, necessary supporting measures should be taken to prevent the removed formwork materials from falling out of the frame. (4) When the height of the shelf is not enough and it is necessary to raise it, a stable and reliable raising method must be used, and the height should not exceed 50cm. When it exceeds 50cm, the paving layer should be raised according to the erection regulations. When raising the working surface, protective facilities should be raised accordingly. (5) When transporting materials on the rack and passing people who are working, please send out "please pay attention" and "please give way" signals in a timely manner. Materials should be placed gently and steadily, and dumping, violent knocking or other hasty unloading methods are not allowed. (6) It is strictly prohibited to play on the shelf, walk backwards, or sit astride the outer protective crossbar to rest. Don't rush, run or jump on the shelf, and be careful not to lose balance when avoiding each other. 7. When performing electrical work on scaffolding, lay an iron sheet to catch sparks or remove flammable materials to prevent sparks from igniting flammable materials. And fire prevention measures should be taken. Once a fire breaks out, put it out in time. 8. Other safety precautions: (1) Vertical transportation facilities or suspension pulleys should be used to lift the rod accessories and be tied firmly. Try to avoid or reduce manual transmission layer by layer.
(2) Except for the necessary 1-2 step up and down steps during the erection process, operators are not allowed to climb up and down the scaffolding. They should take the stairs of the house or set up a separate safety ladder. (3) When erecting scaffolding, unqualified erection materials shall not be used. (4) Operators must obey unified commands and must not act on their own initiative. 9. When the height of the steel pipe scaffolding exceeds the surrounding buildings or is constructed in areas with frequent thunderstorms, lightning protection devices should be installed. Its grounding resistance should not be greater than 4Ω. 10. Rack operations should be used according to the load specified in the specification or design, and overloading is strictly prohibited. And the following requirements should be complied with: (1) Load on the working surface. Including scaffolding boards, personnel, tools and materials, when there is no provision in the construction organization design, it should be controlled by the specified value of the specification, that is, structural scaffolding should not exceed 3kN/m2; decoration scaffolding should not exceed 2kN/m2; maintenance scaffolding should not exceed lkN/m2 . (2) The number of scaffolding layers and simultaneous working layers of the scaffold shall not exceed the regulations. (3) The number of paving layers and load control on the transfer platform between vertical transportation facilities (such as material lifting racks, etc.) and scaffolding should be implemented in accordance with the provisions of the construction organization design. Any increase in the number of paving layers and overloading on the transfer platform are not allowed. Material. (4) The load on the frame surface should be distributed evenly to avoid the load being concentrated on one side. (5) Wall components such as beams must be transported and installed and shall not be stored on scaffolding. (6) Heavier construction equipment (such as electric welding machines, etc.) shall not be placed on scaffolding. It is strictly prohibited to fix formwork supports, cable wind ropes, concrete and mortar delivery pipes, etc. to the scaffolding or hang any lifting equipment. 11. When working on racks, do not dismantle basic structural rods and wall-connecting parts at will. When it is necessary to dismantle certain rods’ self-connecting wall points due to the needs of the operation, you must obtain the consent of the construction supervisor and technical personnel, and take reliable measures. Reinforcement measures can be taken before dismantling. 12. When operating on the rack, do not dismantle the safety protection facilities at will. If they are not installed or the settings do not meet the requirements, they must be added or improved before operations can be carried out on the rack. 13. Before scaffolding dismantling operations, a detailed dismantling construction plan and safety technical measures should be formulated. A technical safety briefing will be conducted for all personnel participating in the operation. Under unified command, the dismantling operation will be carried out in accordance with the determined plan. Notes are as follows: (1) Must be carried out in accordance with the following principles: (1) First up, then down, outside first, inside first, erecting materials first and then framing. The order of materials, auxiliary parts first, structural parts first, structural parts first, wall parts first, loosen the connections one by one, take them out of the well and then hang them down (or gather them on the adjacent undismantled shelf, bundle them and then lift them) Down). (2) When dismantling scaffolding boards, rods, masts and other long, heavy components that are connected at both ends, it must be done in groups of two or more people. It is prohibited for a single person to carry out disassembly work to prevent accidents caused by unstable or unbalanced holding rods. When removing the horizontal rod, loosen the connection. Hold it horizontally and remove it. When dismantling the vertical pole, after holding the upper end firmly, loosen the lower end connection and remove it. (3) When multiple people or groups are performing disassembly operations, command should be strengthened, and they should ask each other and coordinate the operation steps. Any disassembly that does not follow the procedures is strictly prohibited. (4) When the upper or one side wall-attached tie is removed and the shelf becomes unstable, temporary bracing measures should be added to prevent the shaking of the shelf from affecting the safety of the operation. (5) The disassembly site should have reliable safety enclosures and be supervised by dedicated personnel. Non-operators are strictly prohibited from entering the disassembly operation area. (6) It is strictly prohibited to throw the disassembled rod parts and materials to the ground. Erection materials that have been lifted to the ground should be transported out of the disassembly area at any time to maintain civility on site. 14. The foundation (ground) of the scaffolding poles should be flat and compact, with sufficient bearing capacity and stability. When installed on the edge of a pit or on a platform, the distance between the vertical pole and the upper edge of the pit or platform shall not be less than 1m, and the slope of the side slope shall not be greater than the natural resting angle of the soil. Otherwise, the side slope shall be protected and reinforced. Bases and pads must be installed under the scaffolding poles.
