Placard (except for Class 7)
The placard shall be in the form of a square set at an angle of 45° (diamond-shaped). The minimum
dimensions shall be 250 mm x 250 mm (to the edge of the placard). The line inside the edge shall be
parallel and 12.5 mm from the outside of that line to the edge of the placard. The symbol and line

corresponding label, in digits not less than 25 mm high. Where dimensions are not specified, all
features shall be in approximate proportion to those shown.
The Class 7 placard shall be not less than 250 mm by 250 mm with a black line running 5 mm inside

appropriate UN number for the consignment.
For tanks with a capacity of not more than 3 m3 and for small containers, placards may be replaced by
labels conforming to 188.8.131.52. If these labels are not visible from outside the carrying vehicle, placards
according to 184.108.40.206.1 shall also be affixed to both sides and at the rear of the vehicle.
For Classes 1 and 7, if the size and construction of the vehicle are such that the available surface area
is insufficient to affix the prescribed placards, their dimensions may be reduced to 100 mm on each
Orange-coloured plate marking
General orange-coloured plate marking provisions
Transport units carrying dangerous goods shall display two rectangular orange-coloured plates
conforming to 220.127.116.11.1, set in a vertical plane. They shall be affixed one at the front and the other at
the rear of the transport unit, both perpendicular to the longitudinal axis of the transport unit. They
shall be clearly visible.
If a trailer containing dangerous goods is detached from its motor vehicle during carriage of
dangerous goods, an orange-coloured plate shall remain affixed to the rear of the trailer. When tanks
are marked in accordance with 18.104.22.168.3, this plate shall correspond to the most hazardous substance
carried in the tank.
When a hazard identification number is indicated in Column (20) of table A of Chapter 3.2, tankvehicles,
battery vehicles or transport units having one or more tanks carrying dangerous goods shall
in addition display on the sides of each tank, each tank compartment or each element of battery
vehicles, clearly visible and parallel to the longitudinal axis of the vehicle, orange-coloured plates
identical with those prescribed in 22.214.171.124.1. These orange-coloured plates shall bear the hazard
identification number and the UN number prescribed respectively in Columns (20) and (1) of table A
of Chapter 3.2 for each of the substances carried in the tank, in a compartment of the tank or in an
element of a battery vehicle. For MEMUs these requirements shall only apply to tanks with a capacity
of 1 000 litres or more and bulk containers.
For tank-vehicles or transport units having one or more tanks carrying substances with UN Nos. 1202,
1203 or 1223, or aviation fuel classified under UN Nos. 1268 or 1863, but no other dangerous
substance, the orange-coloured plates prescribed in 126.96.36.199.2 need not be affixed if the plates affixed
to the front and rear in accordance with 188.8.131.52.1 bear the hazard identification number and the UN
number prescribed for the most hazardous substance carried, i.e. the substance with the lowest flashpoint.
