Who is primarily responsible for ensuring that the load is rigged safely before lifting?

• A. The operator only.
• B. The designated rigger or signal person.
• C. Maintenance supervisor.
• D. Site safety officer.

Answer: (B)

The person who designs and attaches the rigging—the designated rigger or signal person—is responsible for ensuring the load is rigged safely before lifting. They have the training to evaluate the load, select appropriate slings and hardware, inspect all rigging for wear or damage, and confirm that attachment points, balance, and center of gravity are correct. They set up the rigging properly and use clear signals to guide the crane operator so the lift remains controlled and safe. The operator’s role is to run the crane according to those signals, while maintenance or safety staff oversee equipment condition and safety programs, but they don’t perform the rigging tasks themselves.
