GHS Label Format

The GHS includes directions for application of the hazard communication elements on the label. In particular, it specifies for each hazard, and for each class within the hazard, what signal word, pictogram, and hazard statement should be used. The GHS hazard pictograms, signal words and hazard statements should be located together on the label. The Key Elements for the labels should also include the product identifier, supplier identifier, chemical identity, and precautionary information. The actual label format or layout is not specified in the GHS. National authorities may choose to specify where information should appear on the label or allow supplier discretion. There has been discussion about the size of GHS pictograms and that a GHS pictogram might be confused with a transport pictogram or “diamond”. Transport pictograms are different in appearance than the GHS pictograms. Annex 7 of the Purple Book explains how the GHS pictograms are expected to be proportional to the size of the label text so that generally the GHS pictograms would be smaller than the transport pictograms.

• HMIS is intended for everyday safety, while NFPA is intended for safety during emergency situations, especially fires.
• Because of the varied purposes, it can make sense to use both labels in a workplace. Some employers form a hybrid of the two systems, mixing symbols and standards between the two
• It is important to note the differences between the NFPA 704 and Hazardous Materials Identification System
