Safety Data Sheets (SDSs) contain all the data a downstream user needs to work with a hazardous chemical. Required by law to be provided by the manufacturers of each chemical. The newer, more consistent format (designed in 2012) is comprised of 16 sections and is meant to be much easier to understand all the way around. If you have any questions or would like more information on how to use your SDSs, check out this page on the OSHA website, where they cover every section in detail.
