ANNEX 5HAZARD IDENTIFICATION NUMBER PLACARDThe 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.
HAZARD IDENTIFICATION NUMBERThe hazard identification number consists of two or three figures indicating the following 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. The hazard identification number combinations have following meanings: | ||
