Pictograms are graphical representations, which consist of a symbol and additional graphical elements, such as a border, a background pattern or a background colour.

Annex I Part 1 no. 1.2 of the CLP Regulation specifies, that the hazard pictograms have to be diamond-shaped. In addition, a black symbol must appear on a white background in a clearly visible red frame.

Each hazard pictogram must occupy at least one fifteenth of the minimum area of the label, and shall not have an area below 1 cm² (the minimum area).

The nine hazard pictograms for the individual hazard classes, the differentiations of a hazard class and the hazard categories must correspond to the requirements of Annex V and Annex I, section 1.2 of the CLP Regulation. Regarding the symbols and the general format, they must also comply with the following examples.

The hazard pictograms have a coding system along similar lines to the hazard and safety information. All nine of the pictograms are sorted numerically from GHS01 - GHS09.

Number of required pictograms

The number of required pictograms should not overload the label. Therefore, according to Article 26, paragraph 1 of the CLP Regulation, it is necessary to follow a specific ranking order:

1. If labelling with "GHS01" is required, the use of "GHS02" and "GHS03" is optional
2. If labelling with "GHS06" is required, "GHS07" does not appear.;
3. If labelling with "GHS05" is required, "GHS07" for skin and eye irritation does not appear.
4. If labelling with "GHS08" in combination with H334 (Resp. Sens. 1, 1A, 1B) is required, "GHS07" does not appear in conjunction with H317 (Skin Sens, 1, 1A, 1B), H315 (Skin Irrit. 2) or H319 (Eye Irrit. 2).
5. If labelling with "GHS02" or “GHS06” is required, the use of "GHS04" is optional.

Information on signal words

The signal word is the part of the label that states the extent of the hazard. Its purpose is to notify the reader of the label of a potential hazard. Differentiation is made between two hazard levels:

1. Danger: Signal word for severe hazard categories
2. Warning: Signal word for less severe hazard categories

The CLP Regulation stipulates which signal word is to be assigned and when. The hazard communication tables in Annex I, parts 2 to 5 of the CLP Regulation, detail the required signal words for the individual hazard categories.

Please note the following:

If the classification shows that a signal word should be assigned several times, it will appear only once on the label. If the signal word "Danger" is used, the signal word "Warning" does not appear.

This table provides an overview of the nine hazard pictograms:
