II. Basic Safety Knowledge for Plastering and Masonry Workers
1. When the masonry height exceeds 1.2 meters, scaffolding should be set up for work; for operations above 2 meters (including 2 meters), reliable footholds and protective measures must be provided; the scaffolding must be sturdy and stable.
2. Work at heights should be performed on operating platforms.
3. When breaking bricks, face the wall. After completing the work, clean up the scaffolding boards and debris from the brick walls to prevent falling injuries.
4. Wooden or metal scaffolds used for jointing and plastering must be set up stably and securely. The span of the scaffolding boards shall not exceed 2 meters; the ends of the boards must be secured to prevent overhanging boards; materials stacked on the scaffolding must not be overly concentrated.
5. No more than two operators should work on the same scaffolding board. Tools must be placed properly to prevent falling injuries. Running, playing, or overcrowding on scaffolding is prohibited. Resting against protective railings or lingering in pits is not allowed.
6. If work needs to be performed simultaneously on multiple levels, dedicated protective sheds or other isolation facilities must be provided between the levels. Otherwise, workers must not operate below.
7. Do not stand on balconies or scaffolding railings to perform work.
8. Do not walk, operate, or mark lines on top of walls. Do not use unstable objects to prop up scaffolding boards.
9. Do not throw materials, tools, or debris downward during work.
10. Protective railings, cover plates, and safety signs for reserved openings in buildings must not be moved or removed.
11. When transporting materials with a handcart, pay attention to balance and control the center of gravity. Do not run or let the cart slide when pushing. The distance between carts on flat ground must be at least 2 meters, and at least 10 meters when going downhill. Measures to prevent carts from rolling must be in place at unloading points.
12. No one is allowed to enter the basket before it comes to a complete stop. When using hoist wells (elevators) for transportation, the wheels must be secured, and the hoist must be raised and lowered smoothly.
13. Material loading and unloading are prohibited when vertical transport equipment is not stationary. When waiting for a skip, stand inside the protective door of the unloading platform. Do not stick your head or hands out of the protective door. Close the protective door immediately after the skip is pushed out.
14. Concrete mixer operators must be trained, pass examinations, and hold valid certifications to work.
