physical identification shown on individual packages, used to help move them without delay or confusion to their final destination, and to facilitate verifying goods against their associated documents

two non-reprogrammable data elements [i.e. a unique permanent ID of the integrated circuit (chip ID) and a unique permanent ID of the actual tag (tag ID)] and one reprogrammable data element (the tag data routing code)

NOTE The non-reprogrammable data elements will be imbedded in the shipment tag by the tag manufacturer.

graphic warning devices designed to give the hazard class or division of the dangerous goods carried in a vehicle or railroad car

NOTE There are different placards for each class or division. Placards are colour coded and are at least 10,8 in (273 mm) on a side and must be displayed on all four sides of the vehicle. Placards display the hazard class number in the bottom corner. Some vehicles are required to display more than one placard; some will display three or more.

the four-diamond legend found on buildings and objects, which reflects the hazard degree of the contents.

NOTE Properly called NFPA (National Fire Protection Association) diamonds and based on the 704 standard developed by the NFPA, these symbols are used to provide a gross indication of flammability, instability and other data.

They are similar in intent to the class-divisions numbering found on dangerous goods placards and labels. The four sections contain ratings (ranging from one to four with four as the most severe) as follows: ⎯ The upper triangle (red) is the fire hazard and flash point rating.

⎯ The left triangle (blue) is the health hazard rating.

⎯ The right triangle (yellow) is the reactivity rating.

⎯ The lower triangle (white) is used to reflect any specific hazard indication.
