Transport labels are required to have minimum dimensions of 100mm by 100 mm, with some exceptions for allowing smaller pictograms for very small packagings and for gas cylinders. For example, a flammable liquid transportation label must have the flame pictogram on the upper corner, the word Flammable in the center and the figure (number) 3 in the bottom corner. The label must have a red background with the pictogram, text, and number in black or white. In contrast, GHS labels must have a signal word, corresponding hazard pictograms, hazard and precautionary statements, product, and supplier identification. Each GHS label pictogram consists of a hazard symbol on a white background framed within a red border. There is no size requirement for GHS pictograms as long as they are legible.
