Everyone knows that containers loaded with dangerous goods need to be labeled as transportation components. So, do the colors and details of the label (PLACARD) we post on the container comply with the specifications?
Let's first take a look at the most authoritative IMDG CODE regulations on the size of dangerous goods labels:
5.3.1.2.1
Exceptas provided in 5.3.1.2.2 for the class 7 placard, and in 5.3.2.3.2 for themarine pollutant mark, a placard shall be configured as shown in the figurebelow.

The placard shall be in the form of a squareset at an angle of 45° (diamond-shaped). The minimum dimensions shall be 250 mm × 250 mm (to theedge of the placard). The line inside the edge shall be parallel and12.5 mm from the outside of that line to the edge of the placard. The symboland line inside the edge shall correspond in colour to the label for the classor division of the dangerous goods in question. The class or divisionsymbol/numeral shall be positioned and sized in proportion to those prescribedin 5.2.2.2 for the corresponding class or division of the dangerous goods inquestion. The placard shall display the number of the class or division (andfor goods in class 1, the compatibility group letter) of the dangerous goods inquestion in the manner prescribed in 5.2.2.2 for the corresponding label, indigits not less than 25 mm high. Where dimensions are not specified, allfeatures shall be in approximate proportion to those shown.
The correct signage should be (except for Class 7 and marine pollutants):
The sign must be a square placed at a 45 degree angle (diamond shaped) to the horizontal line. The minimum size must be 250mmX250mm, and the inner edge line must be parallel to the (outer) edge line and 12.5mm apart. The inner edge line and symbol must match the color of the corresponding dangerous goods category or classification mark.
So, what should we pay attention to when we encounter a dangerous goods label that is similar in color to the box? Let's take a look first. Is this label correctly labeled?
We found that the color of the sign is red, and the color of the container box is also red, without a sharp contrast between the two. Regarding this, IMDGCODE has made the following regulations:
5.3.1.1.2
Placards shall be affixed to the exterior surface of cargo transport units to provide a warning that thecontents of the unit are dangerous goods and present risks. Placards shallcorrespond to the primary risk of the goods contained in the cargo transportunit except that:
placards are notrequired on cargo transport units carrying any quantity of explosives ofdivision 1.4, compatibility group S; and
placards indicatingthe highest risk only need be affixed on cargo transport units carryingsubstances and articles of more than one division in class 1.
Placards shall bedisplayed on a background of contrasting colour, or shall have either a dottedor solid outer boundary line.
For dangerous goods of class 9 the placard shall correspond to the labelmodel No. 9 as in 5.2.2.2.2 ; label model No. 9A shall not be used forplacarding purposes.
That is to say, when such a situation occurs, there should be either a virtual or solid outer border.
So, the question arises, where should this outer border be located? The position of the outer border should be between the inner and outer edges of the sign, and there is no detailed regulation on the specific position of IMDG CODE.
