When should straps be taken out of service?

Straps should be taken out of service primarily when the red insert is visible. This indication typically signals that the strap has reached its limit of safe usage and its structural integrity has been compromised. The visibility of the red insert serves as a clear visual warning that the strap has been worn down to the point where it is no longer reliable for secure lifting or rigging operations.

While fraying and overuse can also impact the performance and safety of straps, the appearance of the red insert is a definitive and specific indicator that the strap should be immediately retired from service. Staining alone does not generally affect the strength of the strap, so it is not a valid reason to take the strap out of use unless accompanied by other signs of damage. Hence, monitoring for the visibility of the red insert is crucial for maintaining safety standards in rigging practices.
