In the 2010 crane and derrick final rule, which tasks require third-party certification?

• A. Rigging personnel
• B. Signal operators
• C. Equipment operators
• D. Inspectors

Answer: (C)

The main idea is that the 2010 final rule requires third‑party certification specifically for crane operators to prove they can safely run the equipment. This credential comes from a nationally recognized testing organization or from an employer program that has been evaluated and meets certain criteria. The reason this is the best answer is that the operator is the person who directly controls the crane during lifts, so certifying their ability ensures a standardized level of competency across sites and situations. Other roles—rigging personnel, signal persons, and inspectors—must be trained and qualified, but the rule does not mandate third‑party certification for them; their competency is addressed through training and internal evaluations rather than a formal external certification.
