Which of the following indicates a need for inspection of synthetic rope slings?

The presence of kinks in synthetic rope slings is a clear indication that an inspection is necessary. Kinks can compromise the structural integrity of the sling, potentially leading to weak points that may fail under load. Kinks can prevent the sling from distributing weight evenly and can create additional stress points that increase the likelihood of tear or failure.

While color fading and usual wear and tear might suggest a need for general maintenance or observation, they do not necessarily indicate immediate structural issues. Similarly, length increase could signal excessive stretching or damage but is less direct in suggesting immediate inspection compared to the presence of kinks, which have a direct impact on the functionality and safety of the sling. Kinks present a tangible defect that can affect the usage of the equipment and warrant immediate attention to ensure safety protocols are upheld.
