Marine Pollutant Placards are required for environmentally hazardous substances
Marine Pollutant Placards, also known as Marine Pollutant marks, are required for substances that are deemed environmentally hazardous to aquatic environments. These placards are necessary during the transportation of such substances, as they provide a quick means of identification, ensuring that proper precautions are taken to safeguard the environment.
The Marine Pollutant mark takes two forms: labels and placards. The former is for packages, while the latter is for shipping containers. The specific requirements for the use of these marks are outlined in the Hazardous Materials Regulations (HMR) of the PHMSA/USDOT and the IMDG Code. According to the IMDG Code, the Marine Pollutant mark must be displayed on all four sides of the package or container.
The Marine Pollutant mark consists of a symbol featuring a fish and a tree, with black markings on a white or suitably contrasting background. This symbol is enclosed within a square-on-point configuration, which is also black on a white or contrasting background. The size of the mark may vary depending on the size of the package or container. For packages, the minimum size is 100 mm by 100 mm, while for CTUs (cargo transport units), the minimum size is 250 mm by 250 mm. If necessary, the dimensions can be reduced, but not less than 50 mm by 50 mm.
It is important to note that the display of the Marine Pollutant mark is not always required. If a package or transport vehicle already displays a HazMat label or placard as specified by the Hazardous Material Regulations, then the Marine Pollutant mark may not be necessary. Additionally, when transportation occurs entirely within the United States, the Class 9 Miscellaneous placard may be displayed at the carrier's discretion, but it is not mandatory.

The mark must be visible from the direction it faces
The Marine Pollutant mark is required for substances that are deemed environmentally hazardous to an aquatic environment. The mark must be clearly visible from the direction it faces, with specific size requirements for the mark and placard.
The mark must be displayed on each side and end of the transport vehicle or freight container, with the requirement being met by displaying the mark on the freight container or portable tank. The mark must be in black lettering on a white square-on-point configuration, with the symbol (a fish and a tree) and border in black on a white or suitable contrasting background. This ensures that the mark stands out and can be easily identified.
For bulk packaging that contains a marine pollutant, the Marine Pollutant mark is required on at least two opposing sides or ends, excluding the bottom. If the packaging has a capacity of 3,785 L (1,000 gallons) or more, the mark must be displayed on each end and side. This ensures that regardless of the direction one is viewing the packaging from, the mark is visible and easily recognisable.
Additionally, when a packaging containing a marine pollutant is transported by vessel, the Marine Pollutant mark is required on each bulk and non-bulk packaging. However, when transported by highway, rail, or air, the mark is only required on each bulk packaging containing a marine pollutant and each vehicle or freight container that contains such packaging. It is important to note that the display of a HazMat label or placard specified by regulations may preclude the need for the Marine Pollutant mark.

The mark must appear on each side and end of the transport vehicle
Marine pollutant placards, or marks, are required for substances that are deemed environmentally hazardous to aquatic environments. These placards are necessary for proper identification and classification of dangerous goods during transport and shipment. They are typically displayed on shipping containers and transport vehicles carrying such substances.
The "Marine Pollutant" mark is required on each bulk packaging that contains a marine pollutant and on each vehicle or freight container transporting such packages. This mark must be displayed on each side and end of the transport vehicle, visible from the direction it faces. This ensures that anyone approaching the vehicle from any angle will be able to see the marking clearly.
The specific design of the mark is also important. The mark may be displayed with black lettering on a square-on-point configuration, typically on a white or suitable contrasting background. This design includes a symbol of a fish and a tree, with a black border, ensuring it stands out and is easily recognisable. The placards applied to transport vehicles are required to have a minimum dimension of 250 mm by 250 mm, providing a clear and visible warning.
There are some exceptions to the requirement for displaying the "Marine Pollutant" mark. If a transport vehicle or packaging already displays a HazMat label or placard as specified by the Hazardous Material Regulations, then the "Marine Pollutant" mark is not mandatory. This exception applies even when a placard is displayed at the carrier's discretion and is not required by regulation.
In summary, the "Marine Pollutant" mark is a critical safety measure to identify and classify environmentally hazardous substances during transport. By ensuring this mark is displayed on each side and end of a transport vehicle, it is highly visible to anyone nearby, helping to prevent accidental exposure or potential environmental damage caused by these substances.

The mark must be placed in association with the hazard warning labels
The Marine Pollutant mark is required for substances that are deemed environmentally hazardous to aquatic environments. The mark is placed in association with the hazard warning labels, as per the Hazardous Material Regulations (HMR) of the PHMSA/USDOT. This is applicable to both bulk and non-bulk packaging when transported by vessel.
The Marine Pollutant mark must conform to specific standards. The mark must appear as a symbol (a fish and a tree) in black on a white or suitable contrasting background. The symbol and border must be black, with the background providing a clear contrast. This mark must be displayed on all four sides of the packaging or transport vehicle. The size of the mark may vary depending on the size of the package; for bulk packaging, it must be a minimum of 250 mm by 250 mm, while for non-bulk packaging, it should be a minimum of 100 mm by 100 mm. If the package is small, the dimensions may be reduced to not less than 50 mm by 50 mm.
It is important to note that the display of the Marine Pollutant mark is not always necessary. If a packaging or transport vehicle already displays a HazMat label or placard as specified by the HMR, then the Marine Pollutant mark is not required. This exception applies even when a placard is displayed at the carrier's discretion and is not mandated by regulations.
Additionally, specific provisions are outlined for proper shipping names used to describe hazardous materials that are marine pollutants. If the name is assigned the letter "G" in column (1) of the hazardous materials table or contains the text "n.o.s.," the component making it a marine pollutant must be marked in parentheses with the shipping name. If multiple components contribute to the marine pollutant designation, at least two of the most predominant components must be listed in parentheses with the shipping name.

The Marine Pollutant DOT Placard MPL907 informs personnel of marine pollutants being transported
Marine pollutants are dangerous goods that require proper identification and classification for transport and shipment. The Marine Pollutant DOT Placard MPL907 is one such identification tool. It is used to inform personnel of the presence of marine pollutants being transported. The placard is required on each bulk and non-bulk packaging when transported by vessel, and on each bulk packaging and transport vehicle when transported by highway, rail, or air.
The Marine Pollutant DOT Placard MPL907 is designed to meet the requirements specified by the Transportation of Dangerous Goods (TDG) Directorate. These placards and labels use standardized colours and symbols to identify the hazardous material. In the case of the Marine Pollutant DOT Placard, the symbol is a fish and tree in black on a white or suitable contrasting background. This symbol must be enclosed in a square-on-point configuration, with a black border and a minimum width of 2mm. Each side of the mark must be at least 100mm when applied to non-bulk packages.
The placement of the Marine Pollutant DOT Placard MPL907 is important to ensure visibility. When a package has a capacity of less than 3,785 L (1,000 gallons), the placard must be placed on at least two opposing sides or ends, other than the bottom. If the packaging has a capacity of 3,785 L (1,000 gallons) or more, the placard must be placed on each end and each side. For transport vehicles, the placard must be displayed on each side and each end of the vehicle and must be visible from the direction it faces.
It is important to note that the display of certain HazMat labels or placards, as required by the Hazardous Material Regulations, may preclude the requirement to display the Marine Pollutant DOT Placard MPL907. For example, the Class 9 Miscellaneous placard may be displayed at the discretion of the carrier when transport takes place within the US, but it is not required by regulation.
