What should be ensured regarding the compatibility of fall protection equipment?

Ensuring compatibility between the snap hook, D-ring, and anchor is critical for effective fall protection. Each component must work seamlessly together to maintain safety standards and prevent accidents. The snap hook needs to securely attach to the D-ring on the harness, while the D-ring must be properly rated to handle the forces exerted during a fall. Additionally, the anchor point must be strong enough and appropriately designed to handle the load without failure.

If any of these components are incompatible—such as an incompatible size, strength rating, or locking mechanism—there's a risk that the fall protection system could fail, potentially leading to serious injury or fatality. Thus, verifying the compatibility of all elements in a fall protection system is paramount for ensuring the safety of workers engaged in tasks at heights.
