Pictograms of transport and GHS system

Posted Date:2024/1/5 1

A pictogram is a graphic composition that may include a symbol plus other graphic elements, such as borders, background patterns, or colors, used to convey specific information.

All hazard pictograms used by the Global Harmonization System should be square shapes set at a point.

Transport pictograms

For transport, the pictograms provided for in the Model United Nations Regulations (commonly referred to in transport regulations as labels) should be used. The United Nations Model Regulations specify the specifications for transport pictograms, including colours, symbols, dimensions, contrasting background colours, supplementary safety information (such as types of hazards) and general formats.

The specified size of the transport pictograph is at least 100 mm x 100 mm, but very small containers and gas cylinders can be excepted by using smaller pictograms. Pictograms used in transportation, including symbols on the upper half of labels. The Model United Nations Regulations require that transport pictograms be printed on a chromatic background or attached to the container. The following examples are typical labels produced in accordance with the United Nations Model Regulations for the identification of flammable liquid hazards:

GHS pictograph

The GHS pictograms, unlike the pictograms of the Model United Nations Regulations, use a black symbol with a white background and a red border wide enough to stand out.

However, if such pictograms are used on the labels of packages that are not exported, the competent authorities may also give the supplier or employer the discretion to use black edges at their discretion.

In addition, for packages that do not fall within the scope of the provisions of the Model Regulations of the United Nations, the competent authorities may also permit the use of the Model Regulations pictograms in other contexts of use. The following is an example of a pictograph of the Globally Harmonized System used to identify skin irritants.

Important points to note:

1. Each pictograph has a code that is not part of the pictograph and should not appear on the label or in the safety data sheet in Section 2.

2. In transport, GHS pictograms not required by the Model Regulations of the United Nations may be displayed only as part of the complete GHS label and not independently.

(3) For substances and mixtures falling within the scope of the Model Regulations of the United Nations, the order of the pictograms shall follow the rules of the Model Regulations of the United Nations.

In the case of the workplace, the competent authority may require the use of all symbols of physical danger. For health hazards, the following prioritization principle applies:

(a) If there are skeletons and crossbones, there should be no exclamation marks;

(b) If there is a corrosion symbol, there should be no exclamation mark indicating skin irritation or eye irritation;

(c) If a health hazard symbol for respiratory sensitization is present, no exclamation marks should be used to indicate skin allergy, or to indicate skin irritation or eye irritation.
