Dear Joseph
are we talking about a "Safety Data Sheet" or a "Security Data Sheet" (and what is a "Security Data Sheet"? never heard about)? IN any case:
Nearly any document (related to product safety topics) can be designed using EHS. And then you can download them
For download of Safety Data Sheets: last discussion runs here; No WWI dispatch for EHS WWI CG54 DOKX_EXOMN
C.B.
PS: please read first cross this document if you are new in EHS: SAP EHS Management for Beginners
