What Subpart is Signals for Cranes & Derricks in construction found under?

• A. Subpart CC
• B. Subpart B
• C. Subpart N
• D. Subpart O

Answer: (A)

Signals for cranes and derricks are placed under the crane-focused subpart because this section groups all requirements related to crane operations, including how signaling and communication between the operator and the signal person must be handled. It covers standard hand signals, radio communications, visibility rules, and the responsibilities of the signal person, all in one place to support a clear and consistent crane safety program. The other subparts address different topics, so they don’t specifically govern crane signaling.
