Precautions for exterior wall cleaning

1. High-rise exterior wall works include:
High-rise exterior wall cleaning, high-rise glass curtain cleaning, high-rise exterior wall painting, and high-altitude exterior wall advertising installation. Because of the danger and complexity of high-rise exterior wall engineering, this work has a considerable degree of scientificity and professionalism. Hereby, our construction staff at have been professionally trained and have many times of working at heights. We have always used the sitting sling cleaning method:
1. Sling rope (high-altitude operation rope, scientific name nylon rope, 18 mm in diameter, pulling force of 240,000 Newtons, about two and a half tons).
2. Hanging board (made of Fraxinus mandshurica).
3. Steel wire rope (10 mm in diameter).
4. U-shaped crab buckle (steel).
2. Exterior wall cleaning personnel must undergo professional training and be issued with a qualification certificate for exterior wall cleaning before they can work.
3. Before going to work, you must carefully check the mechanical equipment, appliances, ropes, seat plates, locks, and safety belts for damage, and ensure that the mechanical performance is good and the various appliances are free from abnormal phenomena before they can start operation.
4. The operating rope and safety rope must be tied to two firm fixed points separately, and the dead knot should be tied, and soft objects should be added to the edge of the mouth to prevent the rope from breaking due to wear. The lower end of the rope must be in contact with the ground, and the rope should be laid. People also need to fasten a temporary safety rope.
5. The construction worker must wear overalls and safety helmets before starting work. Before work, he must first wear a seat belt, then fasten the safety lock (on the safety rope), and then fasten the seat plate shackle (on the operation rope) before proceeding. Hanging work.
6. The person in charge of construction shall give on-site command when the rope is off, and the construction personnel shall help each other.
7. Auxiliary appliances should be fastened tightly during operation. To prevent falling and hurting people, it is strictly forbidden to laugh and play and carry other irrelevant items.
8. Supervisors and construction personnel observe the tightness of operating ropes, safety ropes, twisted ropes, stringing and other phenomena at any time, and report problems in time and eliminate them in time.
9. Upstairs guardians are not allowed to walk back and forth on the edge of the roof at will. When necessary, you must first tie your own safety rope, and then perform auxiliary work. Ground guardians are not allowed to read books and newspapers at the construction site, let alone watch other scenes at will. And it is necessary to prevent pedestrians from entering dangerous areas and pulling ropes and throwing ropes at any time.
10. When the operating rope and safety rope need to be moved, up and down, the guardian and auxiliary workers should coordinate and arrange them together, and tie the rope tightly when not in use.
