1. Special operators stipulated by the State of the Shelf shall be trained by relevant departments, pass the examination, and hold a certificate. Should experience once a year. Those suffering from high blood pressure, heart disease, anemia, epilepsy, and unfit for work in high places must not engage in shelf operations.
2. After accepting tasks, workers in the workers’ team must perform safety and technical disclosure to all members of the team according to the characteristics of the tasks and clearly divide the work. Suspended scaffolds, portals, bowl-and-tool and scaffolding scaffolds or other new types of scaffolding, as well as floor-standing scaffolds and other non-standard racks with a height of more than 30 m, must have design drawings, calculations, and approvals approved by superior technical departments. The safety technology can be erected after submitting the book. At the same time, the team leader who set up the front rack must organize all personnel to be familiar with the construction technology and operation requirements and determine the erection method. Before scaffolding, the team leader shall lead the construction worker to inspect the construction environment, necessary tools and safety protection facilities, etc. to eliminate hidden dangers before starting operations.
3. The work industry must use personal protective equipment correctly. Must wear a safety helmet, wear a safety belt, clothing should be flexible, wear soft-soled shoes, do not wear plastic shoes, shoes, slippers and hard bottom or slippery shoes with nails. When working, we must concentrate our thinking, work together, cooperate with each other, and coordinate our command. Do not use the throwing method to transfer tools and parts up and down. No slapsticks and jokes are allowed. Rest on the shelf and rest on the ground. It is forbidden to go to work after drinking.
4. Shelf should be set up in conjunction with the progress of the project. It should not be too high at one time. Unfinished scaffolds must not leave unfixed components when workers leave the work station (such as during work breaks or after work). Measures must be taken to eliminate unsafe factors and ensure shelf stability. After the scaffolding is erected, it must be accepted by the construction staff after passing the acceptance check with the safety officer. During use,
To carry out regular inspections, it is necessary to check the scaffolds that have been disabled for a long time before they can be used again.
5. The uniform load on the multi-pillar external scaffolding of the floor-standing type shall not exceed 270kg per square meter, and only 3 layers shall be allowed to stack on the standard bricks. The concentrated load must not exceed 150kg per square meter. Scaffolds used for decoration must not exceed 200kg/. Understand the hand trucks and over-loaded scaffolding and other types of scaffolding, as required by the design.
6. High-rise building construction site derricks, scaffolding, etc. are higher than the surrounding buildings and must be protected against lightning strikes. If lightning protection devices are installed outside the protection range of lightning protection devices of adjacent buildings and structures, lightning protection devices shall be installed. The height of the derrick frame and the steel pipe scaffold may be lengthened to make it higher than the top 2m as a lightning receptor. The ground bar is provided at the lower end of the high pole. Lightning device impact grounding resistance value shall not exceed 4 ohms.
7. The width of the shelf should not be less than 1.2m. The scaffolding board shall be full of shops, no more than 20cm away from the wall, no gaps and probe boards. When the scaffolding board is overlapped, it must not be less than 20cm. When the head is connected, a double row of small crossbars should be erected with a spacing of no more than 20cm. Skew boards should cross over at the corner of the rack. Flatten the scaffolding using wooden blocks and nail them firmly. Do not use brick mats.
8. The laying width of the loading chute shall not be less than 1.5m, the slope shall not be greater than one to three, and the spacing of the anti-slip strips shall not be greater than 30cm.
9. Outside the scaffold, ramps and platforms, to be tied 1m high protective railings and nails 18cm high footrest.
10. The laying width of the scaffolding in the masonry shall not be less than 1.2m, and the height shall be kept lower than the outer wall by 20cm. The distance between the legs of the scaffolding shall not be greater than 1.5m. There must be a block of wood at the bottom of the bracket, and when it is supported on the structure that can bear the load, when the double shelf is erected, the upper and lower brackets must be aligned, and at the same time the braces should be tied between the brackets. .
11. When the wall height exceeds 4m, a safety net or protective baffle that can withstand 160kg weight must be installed outside the wall. Multi-storey buildings should have a fixed safety net on the second floor and every fourth floor. At the same time, we will set up a safety net that will increase with the construction height.
12. When the scaffold is removed, a fence or warning sign should be set around it and a person should be supervised to prevent anyone from entering the premises. Dismantling shall be performed from top to bottom in a sequence, one step at a time, and simultaneous operations shall not be permitted.
13. When dismantling the scaffold bar and the scissor support, the middle buckle should be removed first, and then the two buckles should be dismantled. The middle operator should move the bar down.
14. Remove the foot bar, scaffolding, steel pipe, fasteners, wire rope and other materials. Should be passed down or suspended with a rope, prohibited throwing down.
