High altitude work is dangerous, a tall building, wind and rain, no cleaning is not good, only in time to clean the work to avoid or reduce the surface damage. Therefore, it is necessary for us to make special introductions to aerial work, cleaning exterior walls or glass curtain walls.

One, the way of cleaning the exterior wall

At present, there are two main ways for external wall cleaning: hanging plate and window cleaning.

The hanging plate is used to lift people to the working position by hanging rope and hanging board. This kind of sound is relatively simple and low cost. As long as the worker's physical quality is good and the rope is firmly connected, the general building can be cleaned in this way, but the operation of this way must make the safety measures in place, otherwise the danger is very high and the casualty accident is caused by the lack of safety measures. Yes.

Two. Conditions for the cleaning of the exterior wall

1, climate conditions: external wall cleaning must be carried out under good climatic conditions. The wind force should be less than 4 grade, and the level of 4 should be stopped. Therefore, the wind force should be measured before work, especially the high-altitude wind force. In addition, rain, snow, fog, poor visibility and high temperature (above 35 degrees Celsius) and low temperature (below 0 degrees Celsius) are not suitable for external wall cleaning.

2. personnel conditions: in order to carry out the national safety regulations and ensure the safety of the workers and the normal operation of the equipment, the high altitude operator must be a male citizen of 18 years of age, and through the physical examination and the training of safety and technology, the workers are qualified to work through the examination. The workers are not allowed to drink alcohol before the job, and there are cold and other bodies. When the symptoms are suitable, the high altitude operation is suspended.

3, equipment conditions: the wall cleaning equipment must be in good working condition, and the new rope should be replaced immediately if the hanging board has hair and part of the strand is split.

Three. Safety operation rules

L, before going to work, we must carefully check the mechanical equipment, equipment, rope, board, safety with no damage, ensure that the mechanical performance is good and all kinds of appliances have no abnormal phenomenon.

2, the operating rope, the safety rope must be separated and fastened to the dead, the soft objects should be added at the edge of the mouth to prevent the rope broken by wear. The lower end of the rope must contact the ground, and the ropes should also be a temporary safety rope.

3, the constructors should wear good work clothes and wear safety helmets before they go on duty. When they go on guard, they should be fastened first and then the safety lock (on the safety rope). Then, they are then fastened (on the operating rope). At the same time, the board buttons should be tightened and fixed.

4. When the rope is lowered, the construction supervisor and the upstairs guardians should be given command and assistance.

5. During operation, the auxiliary equipment should be fastened firmly to prevent injury.

6, the upstairs and ground guardians should stick to the construction site and perform their duties. At any time, we should observe the tightness of the operating rope, the safety rope and the rope, string and other phenomena, and find out the problems in time and eliminate it in time.

7. Upstairs guardians are not allowed to walk back and forth on the edge of the roof. When necessary, the safety rope must first be tied up, and then the auxiliary work will be done afterwards. Ground guardians should not read or read newspapers at the construction site, nor should they watch other scenes at will.  And at any time to stop pedestrians into dangerous areas and pull rope, rope phenomenon occurs.

8. When the operation rope and safety rope need to be shifted and up and down, the guardians and auxiliary workers should coordinate with each other well.

9, when the builder wants to fall to the ground, we should first look at the facilities of the ground and wall, the location of the operation rope, the safety rope and the number of pedestrian flow, and wait for the ground guardianship to handle and adjust, and agree to the slow decline until the ground.

10, we must insist on safety first, civilized construction, and ensure the quality of engineering services.

11. No Party A or customer's articles are allowed to be damaged. No Party A or customer's facilities can be damaged.

12, aerial work personnel and field guardians must obey the unified command and unified management of the person in charge of construction.
