How often should high-altitude work safety belts be inspected?
3 Answers
High-altitude work safety belts should be inspected every three years. Below is an introduction to related information about safety belts: 1. Function: The role of safety belts is to constrain displacement and provide cushioning, absorbing impact energy, mitigating inertial forces, and preventing or reducing the extent of injuries to drivers and passengers. Car accident investigations show that wearing seat belts can reduce fatalities by 57% in frontal collisions, 44% in side collisions, and 80% in rollovers. 2. Principle: When a severe frontal collision occurs, due to inertia, the driver's and passengers' bodies move forward rapidly. At this point, the safety belt will exert force to "pull back" the bodies, absorbing part of the impact energy, while the airbag inflates and fully deploys.
As a seasoned veteran in aerial work, I've summarized several key safety practices: Always thoroughly inspect your safety harness before each use—this is fundamental. Conduct a comprehensive check at least once a week, paying special attention to potential deformities in metal hooks, cuts in the webbing, or loose stitching. If you spot even the slightest issue, like minor fraying, replace the harness immediately. Even if a frequently used harness appears intact externally, internal fibers may have aged and become brittle. On our sites, we mandate the replacement of all harnesses every six months. Aerial work safety is no joke—I've personally witnessed a colleague nearly lose their life due to a faulty harness buckle.
Having been responsible for construction site safety management for so many years, our operating procedures are very clear: all workers engaged in high-altitude operations must conduct mutual safety harness inspections during pre-shift meetings, with a focus on the flexibility of waist belt buckles and wear at load-bearing points. The safety department conducts random checks on maintenance records every Wednesday and organizes tension tests. According to the requirements of the national standard GB6095-2020, safety harnesses must be sent for professional inspection every 12 months. However, in actual construction, after operations in severe weather conditions or high-intensity continuous use, we always arrange additional surprise inspections.
