What percentage of chemical anchors must be proof tested to 100% of their WLL?

The requirement that 100% of chemical anchors must be proof tested to 100% of their Working Load Limit (WLL) is grounded in safety and reliability standards for rigging operations. When anchors are used, especially those relying on chemical bonds, ensuring that each anchor can handle its designated load without failure is critical for preventing accidents and ensuring the safety of personnel and equipment.

Proof testing to the full WLL demonstrates that the anchors have been installed correctly and have achieved the necessary bond strength to withstand real-world conditions. This level of testing is vital because even one anchor failing under load can lead to catastrophic results, particularly in high-stakes environments such as construction or industrial settings.

By mandating that all chemical anchors are fully proof tested, safety protocols ensure that the maximum capacity of the equipment is reliable, minimizing the risk associated with potential overload situations. This rigorous standard helps maintain the integrity of the rigging system and supports a culture of safety within operational practices.
