Question 1469 Deck General

The correct answer is C) "Warning, No Smoking, No Open Lights, No Visitors". This is the correct answer because the sign used to caution persons approaching the gangway of a tank barge during cargo transfer should provide clear instructions to avoid potential ignition sources and restrict unauthorized access to the area. The sign needs to convey the hazardous nature of the cargo transfer operations and the specific safety precautions that must be observed. The other options are incorrect because they either do not provide the necessary level of detail (A and B) or do not accurately describe the specific hazards and restrictions (D).
