Question: 1 / 460

During a rigging inspection, a hook should be replaced if the throat opening has increased by more than what percentage?

10 percent

15 percent

The correct percentage for replacing a hook during a rigging inspection is 15 percent. This standard is based on guidelines established by safety organizations, which recognize that any alteration in the dimensions of a hook can affect its strength and reliability. An increase in the throat opening by more than 15 percent indicates potential wear or damage that could compromise the hook’s integrity, leading to safety hazards during lifting operations.

Therefore, replacing the hook if this threshold is exceeded helps to ensure that all rigging equipment remains within safe operational limits, thus enhancing overall safety on the job site.
