Real life applications normally involve many other types of forces and factors which will cause the rope to fail at much reduced loads. Accordingly, the safe working load of any rope is much lower than its nominal strength. In life threatening and similar critical conditions, the safe working load should not exceed 1/15 of the rated breaking strength. In non-life threatening applications, a safe working load of 1/5 of the rated strength may be acceptable. Photo Cred: Corey Hackley using Greenline ropes in J2, Last Bash by Elliot Stahl
