Associate Safety Professional Practice Exam

When inspecting a hoisting and lifting chain hook, the measurement between the shank and the throat should not exceed what percentage of the original dimension?

1. 0.10

2. 0.15

3. 0.20

4. 0.25

The correct answer is: 0.15

When inspecting a hoisting and lifting chain hook, the critical measurement between the shank and the throat must not exceed 15 percent of the original dimension. This is essential because an excessive increase in this measurement indicates wear, deformation, or damage that can compromise the hook's integrity and its capability to safely support loads. Maintaining the appropriate dimensional tolerances is crucial in ensuring safe operational practices. If the measurement exceeds this threshold, it suggests that the hook may be weakened and could potentially fail during use, posing significant safety risks. This standard aligns with best practices for equipment inspection and maintenance, aiming to ensure that all lifting devices remain within safe operational limits. By focusing on this 15 percent standard, safety professionals can help prevent accidents and ensure compliance with industry regulations regarding lifting equipment.
