Which of the following is NOT one of the three things to verify before leaving zip?

• A. No going upside down
• B. One hand on
• C. No touch the metal
• D. Two hands on

Answer: (D)

Before leaving the zip, you verify three safety points to stay in control and in a safe position: you remain upright (not inverted), you keep one hand on the trolley to maintain connection and balance, and you do not touch the metal parts to avoid pinch points or moving components. The notion of having two hands on isn’t part of that standard checklist, so it’s the one that doesn’t belong.
