Features: II. Basic Safety Operation Knowledge
1. Individuals with hypertension, heart disease, epilepsy, acrophobia, or other diseases are not allowed to operate on scaffolding; alcohol consumption is strictly prohibited before working on scaffolding.
2. When erecting scaffolding, safety harnesses must be worn, hard hats must be worn, soft-soled shoes must be worn, and pants and sleeves must be properly fastened.
3. During scaffolding construction, sleepers should be laid flat without any gaps to prevent overall or localized settlement of the scaffolding.
4. Severely rusted, crushed, bent, or cracked steel pipes are strictly prohibited for use in scaffolding construction. Fasteners with cracks, deformation, or stripped threads must not be used.
5. Mixing steel pipes with outer diameters of 48 mm and 51 mm is strictly forbidden.
6. Tool bags must be provided for work at heights, and tools must be placed in the tool bags at all times.
7. Scaffolding must be erected in coordination with construction progress, and the height of each section should not exceed two steps above the adjacent tie-in.
8. During scaffolding construction, operators must ensure the tightness of the fasteners.
9. Personnel must use designated access routes for entering and exiting scaffolding; climbing scaffolding members is strictly prohibited.
10. Scaffolding boards must be securely fastened.
11. When working or walking on the work platform, be cautious of overhanging boards.
12. Scaffolding must be enclosed with safety netting. The work platform must be fully covered with scaffolding boards, and 12-meter-high guardrails must be installed on the outside. A 18-cm-high toe board must be installed on the outer edge at the bottom.
13. The overlap length of diagonal bracing steel pipes should not be less than 1 meter and must be fixed using at least two swivel fasteners. The edge of the cover plate of the end fastener should be at least 100 mm away from the pipe end.
14. Both ends of straight and open scaffolding must be equipped with tie-ins. The vertical spacing of tie-ins should not exceed the height of the building story and should not exceed 4 meters (2 steps).
15. Lower-level workers are strictly prohibited from resting under guardrails, platforms, or other protective barriers.
16. During cross-training, workers must not operate on the same vertical line when performing vertical cross-training. The lower-level work area must be outside the potential falling range of upper-level work objects. If this cannot be ensured, isolation barriers must be installed between the upper and lower levels.
17. Work at heights must be suspended during severe weather conditions such as winds, heavy rain or snow, severe frost, or dense fog. Work must only resume after the surrounding area is cleared and anti-slip measures are taken.
18. During the use of scaffolding, the longitudinal and transverse horizontal members, longitudinal and transverse, and tie-ins at the main connection points must not be removed.
19. When moving scaffolding boards, two people must work together from the outside in, following the correct sequence. When moving the last board or the next-to-last board, safety harnesses must be securely fastened before operation.
