🔍 Key Concepts

• 46 CFR requirements for emergency shutdowns on tank vessels and hazardous liquid transfer systems • Purpose of emergency shutdowns during cargo transfer operations • What types of equipment present an immediate pollution or cargo hazard if they keep running in an emergency

💭 Think About

• Which of these systems, if it failed or had a hose rupture, could quickly cause a major spill or hazardous release during loading or discharging? • Which equipment is directly involved in moving oil or hazardous liquid between ship and shore? • Think about where U.S. regulations focus their emergency stop devices: on systems that must be stopped immediately to prevent escalation of a cargo or pollution emergency.

✅ Before You Answer

• Verify which option is directly tied to liquid cargo movement between vessel and shore or between tanks • Check 46 CFR sections on emergency shutdowns/E‑stops for tank vessels and transfer operations • Confirm that the chosen system is one that, by design, must have a remote means to quickly stop flow in an emergency
