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 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. Safety data sheet The safety data sheet or SDS (the GHS dropped the word "material" from "material safety data sheet" in its final revisions) is specifically aimed at use in the workplace. It should provide comprehensive information about the chemical product that allows employers and workers to obtain concise, relevant and accurate information in perspective to the hazards, uses and risk management of the chemical product in the workplace. While there were some differences in existing industry recommendations and country specific requirements, there was agreement on a 16-section SDS to include the following headings in the order specified: Identification Hazard(s) identification Composition/ information on ingredients First-aid measures Fire-fighting measures Accidental release measures Handling and storage Exposure control/ personal protection Physical and chemical properties Chemical stability and reactivity Toxicological information Ecological information Disposal considerations Transport information Regulatory information Other information The primary difference between the GHS and the international industry recommendations is that sections 2 and 3 have been reversed in order. The GHS SDS headings, sequence and content are similar to the ISO, European Union and ANSI MSDS/SDS requirements. The SDS should provide a clear description of the data used to identify the hazards. A table comparing the content and format of a MSDS/SDS versus the GHS SDS is provided in Appendix A of the U.S. Occupational Safety and Health Administration (OSHA) GHS guidance. Training Current training procedures for Hazard Communication in the United States are more detailed than the GHS training recommendations.
