Construction work on telecommunication towers is a high-altitude, hazardous operation, requiring strict adherence to safety regulations to prevent accidents. For example, on November 15, 2020, a worker fell to his death during 5G equipment installation work on a telecommunication tower in Bayannur City. The direct cause of the accident was the worker's failure to properly wear and use safety helmets, safety belts, and other protective equipment. Indirect causes included the lack of safety cages and ladder platforms on the tower, and the absence of safety warning signs at the site.
Daily maintenance and emergency response work on telecommunication towers often faces challenges related to harsh environments and difficult conditions. For instance, during the 2026 Spring Festival travel rush on the Sichuan-Qinghai Railway, some base stations were located in remote areas where roads leading to them were narrow and icy, making them impassable by vehicles. Maintenance personnel had to trek on foot through the ice to reach these stations. Telecommunications workers must climb 40-meter-high iron towers at an altitude of about 3,000 meters and a temperature of minus 15 degrees Celsius to carry out maintenance work, facing multiple difficulties such as lack of oxygen, cold, fear of heights, and the tower swaying in the wind.
