For the purpose of this website SDS and MSDS are synonymous. Most people are still searching for MSDS, and for that reason we’ve continued to use the phrase ourselves. SDS books, (M)sds books, (formerly Msds Books) are what is described within these pages. We are now printing all new Msds binders with “SDS” or safety data sheets. Our Osha compliant hazard communications program template and all of the content on this site is compliant with Osha's latest regulations.
