What should be done to the eyes of a fiber rope if the thimbles are loose during an inspection?

When thimbles in the eyes of a fiber rope are found to be loose during an inspection, seizing is the appropriate action to take. Seizing involves wrapping a smaller diameter rope or twine tightly around the eye of the fiber rope where the thimble is located. This effectively secures the thimble in place and helps to maintain the integrity and functionality of the sling.

This practice is not only a practical solution for securing a loose thimble but also helps to prevent further deterioration of the rope, which could occur if the thimble continues to move or shift during use. Seizing provides additional strength and stability to the eye, ensuring the fiber rope can be safely used once again.

Other actions such as cutting, twisting, or replacing the rope are not as suitable in this scenario. Cutting the fiber rope may render it unusable and compromise safety. Twisting would likely exacerbate any issues with the thimble and not provide the required security. While replacing the rope with a new one is a possible solution, it may be unnecessary if seizing can address the issue effectively. Therefore, seizing is the recommended corrective measure in this situation.
