Safety Data Sheets (SDS), or Material Safety Data Sheets (MSDS) are guides to hazardous materials, often provided by chemical manufacturers and distributors. The sheets include:
The Hazard Communication Standard (HCS) (29 CFR 1910.1200(g)), revised in 2012, requires that the chemical manufacturer, distributor, or importer provide Safety Data Sheets (SDSs) (formerly MSDSs or Material Safety Data Sheets) for each hazardous chemical to downstream users to communicate information on these hazards. The information contained in the SDS is largely the same as the MSDS, except now the SDSs are required to be presented in a consistent user-friendly, 16-section format.
Where to find MSDS and SDS on the Internet lists a number of MSDS collections, including government and chemical supplier websites. Some require registration or a fee, so check the comments.
