What should you never do with the fly system?

• A. Use it if you are careful.
• B. Never use it if untrained or working alone.
• C. Always have a partner but not trained.
• D. Ignore training; proceed.

Answer: (B)

Operating a fly system depends on proper training, clear procedures, and coordinated teamwork. You should never use a fly system if you are untrained or working alone because mishandling the rigging or moving loads can cause the batten to fall, injure people, or damage stage equipment. Training teaches how to correctly balance weights, check hardware, communicate with the crew, and react to jams or sudden movements, which are essential safety steps. Having a partner who isn’t trained doesn’t replace this protection, since the critical procedures and risk awareness come from that training. Merely being careful won’t cover all the risks, and ignoring training and proceeding is visibly unsafe. So the safe rule is to never operate the fly system unless you are trained and not working alone.
