Some points to note when cleaning external walls
High-altitude work poses significant challenges for cleaning companies, yet it is also a high-risk and high-reward industry. While constructing or maintaining high-rise buildings is not advisable, cleaning their exteriors—such as glass facades or outer walls—requires careful planning and execution. Improper methods can lead to surface damage and safety hazards, which is why a detailed guide on high-altitude operations is essential.
There are two primary methods used for exterior wall cleaning: the hanging board technique and window cleaning. The hanging board method involves using a rope or a platform to lift workers to the required height. This approach is cost-effective and straightforward, provided that the workers are physically fit and the ropes are securely fastened. However, due to the inherent risks involved, strict safety protocols must be followed to prevent accidents.
When it comes to the conditions for exterior wall cleaning, several factors must be considered. First, weather plays a crucial role. Cleaning should only be conducted under favorable conditions, with wind speeds below level 4. If winds reach level 4 or higher, work must be suspended immediately. Rain, snow, fog, extreme temperatures (above 35°C or below 0°C), and poor visibility also make it unsafe to proceed.
Personnel requirements are equally important. Operators must be male citizens over 18 years old, undergo medical check-ups, and complete safety training. They must not consume alcohol before starting work and should avoid performing tasks if they have cold symptoms or other health issues.
Equipment must also be in optimal condition. Ropes used for hanging boards should be regularly inspected for wear and tear, and any damaged ropes must be replaced immediately to avoid accidents.
Safety procedures are critical during high-altitude operations. Before beginning work, all equipment—including ropes, harnesses, and safety belts—must be thoroughly checked for damage. Operating and safety ropes must be properly secured, with soft padding placed along the edges to prevent friction-related breakage. The lower end of the rope should touch the ground, and a temporary safety rope should be used when releasing the main line.
Workers should wear appropriate protective gear, such as overalls and helmets, and always secure their safety belts and locks before starting. Communication between the person in charge and the ground guardian is essential throughout the process. All tools and materials must be securely fastened, and workers should avoid distractions or unnecessary movements.
Ground and upper-level guardians must remain at their posts, monitoring the situation continuously and reporting any issues promptly. They must not engage in unrelated activities or allow unauthorized people into the area. When moving ropes, coordination between team members is necessary to ensure smooth and safe operation.
Before descending, workers must confirm the stability of the surrounding area, including the positioning of ropes and the presence of pedestrians. Only after receiving approval from the ground guardian can they begin their descent.
Finally, safety and professionalism should always be prioritized. Workers must respect the property of clients and follow the instructions of the project manager. By adhering to these guidelines, high-altitude cleaning can be performed safely and efficiently, ensuring both worker well-being and quality service delivery.
