The hook or rope of the seat belt should be hung on a sturdy and sturdy component, or on a steel wire rope specifically designed for hanging the seat belt. It is prohibited to hang it on moving or unstable objects. When working at heights, a tool bag should be used, and larger tools should be tied to a sturdy component with ropes. Random placement is not allowed to prevent accidents from falling from heights.
When using a curved arm aerial work platform for high altitude work, except for relevant personnel, no one is allowed to pass or stay below the work site. There should be fences or other protective devices installed below the work site to prevent falling objects from injuring people. If working on a grid platform, wooden boards should be laid to prevent tools and equipment from falling off. Curved arm elevators are not allowed to throw tools and materials up and down. They must be securely tied with ropes before being lifted downwards or upwards to avoid injuring the workers below or damaging the scaffolding. When both upper and lower layers are working simultaneously, a tight and secure protective partition, canopy, or other isolation facility must be erected in the middle.
Workers must wear safety helmets. In severe weather such as strong wind of level 6 and above, rainstorm, thunder and fog, outdoor work at heights should be stopped. It is forbidden to work on unstable structures (such as asbestos tile roofs). To prevent false boarding, warning signs should be hung at necessary places of such structures.
