Dangerous goods recognition
Introduction of dangerous goods recognition
Hazardous goods requiring supervision. Transport units and vehicles carrying dangerous goods in quantities above the values indicated should be supervised. Tank cars and tank containers running by road under international ADR regulations. These transport units have an ADR Hazard Identification Number HIN (The Kemler Code).
The ADR Hazard Identification Number HIN (The Kemler Code)
The ADR Hazard Identification Number HIN, also known as the Kemler Code, is carried on placards on tank cars and tank containers running by road under international ADR regulations.
The following identification system is in use for placards in Europe (ADR) for road transport. The background of the placard is orange. The border, horizontal line, and figures are black.
Identification numbers are shown in such a way, that the upper number is indicating the danger and the lower number identifies the substances with the UN-number given in the UN Recommendations on the Transport of Dangerous Goods.
An orange blank placard without any numbers indicates vehicle carrying dangerous load (drums, packages, etc.) or multi-load tanker.
The ADR Hazard Identification Number HIN consists of two or three figures. The first figure of the Kemler Code indicates the primary hazard:
The second and third figure generally indicate secondary hazards:
Doubling of a figure indicates an intensification of that particular hazard. Where the hazard associated with a substance can be adequately indicated by a single figure, this is followed by a zero.
If a hazard identification number is prefixed by letter 'X', this indicates that the substance will react dangerously with water.
Recognizing Hazard Identification Number placards
ARH Inc. developed a special recognition software which is capable of recognizing ADR Hazard Identification Number HIN placards. The CARMEN Dangerous Goods Recognition software offers great flexibility for manufacturers and integrators of various recognition systems.
It is highly accurate, fail safe and stable. It provides the highest technological performance amongst today's ANPR/LPR readers. It can be integrated into practically any vehicle identification system which needs automatic transport unit recognition.
The CARMEN Dangerous Goods Recognition Software Development Kit (SDK) makes integration of optical plate recognition easy, fast and cost effective. And the resulted image processing system will have the highest performance.
