A full body harness is a component of personal systems protecting against falls from a height. To ensure users' safety, the harness must retain its protective properties during its whole service period. All the elements of a harness (webbings, threads, metal buckles, etc.) are exposed to destructive factors. Harnesses stored and used for a few years were tested. The paper discusses the most frequent types of damage and their effect on the essential resistance parameters. The effect of atmospheric conditions, sunlight, mechanical damage and dust on the parameters of webbings was tested. Conclusions on the main causes of the loss of the protective properties of harnesses are drawn; periodic checks of the physical conditions and guidelines for estimating acceptable service time are recommended.
全身安全带是防止高空坠落的个人防护系统的组成部分。为了确保使用者的安全，安全带在整个使用期间必须保持其防护性能。安全带的所有部件（织带、缝线、金属卡扣等）都受到破坏性因素的影响。对储存和使用了几年的安全带进行了测试。本文讨论了最常见的损坏类型及其对基本阻力参数的影响。测试了环境条件、阳光、机械损坏和灰尘对织带参数的影响。得出了导致安全带失去防护性能的主要原因的结论；建议定期检查物理状况并制定估计可接受使用时间的指南。
