🔍 Key Concepts

• 33 CFR regulations on signs and warnings during transfer of flammable or combustible liquids • The specific hazards present on a tank barge during cargo transfer (vapors, ignition sources, access control) • Difference between a general danger sign and a detailed safety precaution sign

💭 Think About

• Which option best addresses all key risks during a tank barge cargo transfer: fire/explosion, ignition sources, and unauthorized visitors? • Look for wording that would meet a Coast Guard inspector’s expectations for clarity and completeness in warning people near the gangway. • Ask yourself: during a volatile cargo transfer, what exact behaviors must be prevented, and which choice explicitly tells people not to do those things?

✅ Before You Answer

• Verify which option clearly prohibits smoking and open flames, not just boarding. • Check which wording most clearly controls access/visitors to the barge during transfer. • Confirm that the sign describes specific prohibited actions, not only a general danger or cargo condition.
