Workplaces are required to have a safety data sheet (SDS – aka material safety data sheets) on site for each hazardous substance held, where the amount held is above a particular threshold (see http://goo.gl/pgDuRK).
Suppliers are legally required to supply SDS documentation and must supply them when requested. You can find out if a substance is classified as hazardous here: https://bit.ly/2rMeVSH. If in doubt, call the Environmental Protection Agency hotline on 0800 429 7827.
If you want to investigate a substance further, the ILO has a great database of chemical safety cards here: http://goo.gl/hJd0SZ. There is also has a huge collection of U.S. fact sheets here: http://goo.gl/ZEMzS. WorkSafe also has advice on working with organic solvents here: http://goo.gl/Z4iHFI.
Remember – it’s not just about having the right documentation – people must know where it is and how to access it! A good place to start reviewing your systems is the EPA Hazardous Substances Toolbox: http://goo.gl/Ug16nP.
