For shipments containing Marine Pollutants, what must be added to the shipping paper?

• A. The words 'Marine Pollutant' and the Technical Name(s) of the Marine Pollutant
• B. The phrase 'Sea Hazard'
• C. The environmental impact rating only
• D. The port of discharge

Answer: (B)

When a shipment contains a marine pollutant, the shipping paper needs a clear indicator that the material can harm the marine environment. The best way to communicate this quickly is to add the phrase “Sea Hazard” to the shipping paper. This notation alerts everyone handling the load—shippers, carriers, and emergency responders—that the substance poses a risk to the sea and requires appropriate precautions and response measures in the event of a spill or accident. It complements the standard shipping paper data (identity, UN number, hazard class, etc.) by specifically flagging its marine environmental hazard. The other options don’t provide that direct, at-a-glance marine warning: environmental impact rating alone isn’t a transport-facing alert, the port of discharge isn’t the required shipping-paper addition, and simply citing the environmental effect without a clear designation wouldn’t rapidly convey the marine hazard during transport.
