🔍 Key Concepts

• Standard crane hand signals for emergency stop • Difference between a normal stop and an emergency stop signal • Why emergency signals must be highly visible and unmistakable

💭 Think About

• Which motion, if the operator saw it from far away, would clearly look like an URGENT stop and not be confused with any other command? • Which choice shows a big, rapid movement instead of a small or static position? • Think about which signal would most quickly catch the crane operator’s attention in a noisy, busy environment.

✅ Before You Answer

• Verify which option involves a rapid side‑to‑side motion that stands out as an urgent command. • Check which signals are static positions that might be used for other purposes, not for an emergency. • Ask yourself: which signal would safety trainers emphasize as the universal emergency stop for cranes?
