🔍 Key Concepts

• Standard hand signals for crane/hoist operations used on deck and in engine rooms • Difference between signals for directional movement (left/right/swing) and status commands (stop/keep going) • Body position and palm direction (up vs down) and what they usually indicate

💭 Think About

• Ask yourself: does a side‑to‑side arm motion with palms down more commonly indicate a change in direction, a continuation of movement, or an urgent command to halt? • Think about which signal would need to be highly visible and unmistakable to prevent damage or injury if something goes wrong during a lift. • Visualize the other common signals: how would a signalman usually indicate swing left or right compared with a signal to continue or to stop?

✅ Before You Answer

• Confirm which of these choices would logically need the most distinct and urgent signal. • Check if both arms extended, palms down, moving back and forth is symmetrical (not pointing left or right), and decide if that matches a left/right swing command. • Before choosing, rule out any option that would more likely use one arm pointing in the direction of travel rather than two arms moving together.
