If you want someone else to add an MSDS, email a pdf or send a request to admin@stratussafety.net and it will be added to the files.
Select the "MSDS Library" project, click "files" in the top ribbon, click "add a file" (next to add a folder), and you will see this.
Browse for the file you have saved.
Select the MSDS Files folder
Select the options shown.
