Which signal must you display at night on a docked tank barge to show that it is loading or discharging flammable liquid cargo?
β’ Special signals for tank vessels handling flammable or combustible cargo alongside a dock β’ Difference between day shapes (like flags or shapes) and night signals (lights) for dangerous cargo operations β’ Where these requirements are found in 46 CFR and how they apply to barges vs self-propelled tankers
β’ Ask yourself: what is the traditional, internationally recognized danger signal for vessels engaged in hazardous cargo operations at night? β’ Think about which of these options would be easily recognized from a distance as a warning to other vessels and people near the dock. β’ Consider whether the signal should be steady-burning or flashing, and why that matters for cargo transfer operations.
β’ Verify in 46 CFR the required light color used to indicate transfer of flammable liquids on a tank vessel or barge at night. β’ Check whether the regulation calls for one light or multiple lights, and if they must be visible all around the horizon. β’ Confirm if any of the listed options (ICC yellow, flashing amber, orange lights) are actually named in the current U.S. regulations for this specific situation.
