Aerial Cleaning Conditions and Safety Operating Procedures

High-altitude work is inherently dangerous. With skyscrapers exposed to wind and rain, neglecting cleaning is simply not an option. Only by conducting regular cleaning can damage to the exterior surfaces be avoided or minimized. Therefore, it is necessary to provide a specialized introduction to high-altitude operations, exterior wall cleaning, or glass curtain wall cleaning.

Washing Methods for the Exterior Wall

Currently, there are two main methods for exterior wall cleaning: the hoist board method and the window wiping method.

The hoisting method involves using ropes and hoisting boards to lift individuals to the work position for cleaning. This method is relatively simple and cost-effective, as long as workers are physically fit and the rope connections are secure. It is generally suitable for cleaning most buildings. However, this method requires strict adherence to safety measures, as failure to do so poses significant risks and accidents resulting in injuries are usually due to inadequate safety precautions.

Section II: Conditions for Exteriors Cleaning

1. Weather Conditions:外墙cleaning must be conducted under favorable weather conditions, with wind speeds less than 4 levels; work should cease above 4 levels. Therefore, wind measurements should be taken prior to work, especially for high-altitude winds. Additionally, wall cleaning is not suitable during rain, snow, fog, low visibility, extreme temperatures (above 35℃ or below 0℃).

2. Personnel Requirements: To enforce safety regulations and ensure the personal safety of workers and the normal operation of equipment, it is stipulated that high-altitude operators must be male citizens aged 18 or older, have passed physical examinations and safety technology training, and are qualified to perform work after passing an exam. Workers are prohibited from drinking before starting work and should suspend high-altitude operations if they have symptoms of cold or other physical discomfort.

3. Equipment Condition: The equipment for exterior wall cleaning must be in good working order. Any signs of fraying on the slings or partial rope strands showing signs of cracking should be immediately replaced with new ropes.

Section III: Safety Operating Procedures

Before starting work, all machinery, tools, ropes, seats, and seat belts must be thoroughly inspected for any damage to ensure proper mechanical performance and no abnormal conditions with the tools before operation.

2. Operating ropes and safety ropes must be separately anchored and securely tied. A soft pad should be added at the edge to prevent rope breakage due to wear. The lower end of the rope must always touch the ground. The person releasing the rope must also tie a temporary safety rope.

3. Before taking up their duties, construction workers must wear proper work attire and a safety helmet. Upon starting work, they should first fasten their safety belt, then secure the safety lock (on the safety rope), followed by properly tying the release buckle (on the operation rope). Additionally, the seat buckle must be tightened and firmly secured.

During the rope lowering process, the construction supervisor and the on-site supervisor on the upper floor should provide guidance and assistance.

5. Ensure that auxiliary tools are tightly secured during operation to prevent injury from falling. Additionally, strictly prohibit laughing, joking, and carrying unrelated items.

6. Supervisors and ground personnel must remain vigilant at the construction site. They must diligently fulfill their duties, constantly monitor the tension of the operation rope and safety rope, as well as the twisting and intertwining of ropes, and report any issues promptly, addressing them immediately.

7. Supervisors on the upper floors are prohibited from walking along the edge of the rooftop at will. In case of necessity, they must secure their own safety harness first before performing any assisting tasks. Ground supervisors are not allowed to read books or newspapers at the construction site and should not casually observe other scenes. They must also promptly stop pedestrians from entering dangerous areas and prevent the occurrence of rope pulling or throwing.

8. When moving operation ropes or safety lines, the supervisors and auxiliary workers must coordinate and properly secure their placement. When not in use, the ropes should be tied and bundled securely.

9. When the construction worker is about to descend, they must first inspect the ground and wall facilities, the positioning of the operation rope and safety rope, and the amount of pedestrian traffic. They should wait for ground supervisors to handle and adjust, and only then can they descend slowly until reaching the ground.

10. Uphold safety and civilized construction practices to ensure the quality of engineering services.

11. No unauthorized removal of items belonging to Party A or clients. No damage to Party A's or clients' facilities.

Workers performing high-altitude operations and on-site supervisors must comply with the instructions and management of the construction supervisor.
