3/11/2026 update: IT has been actively working to resolve the issue.  Users must ensure they have the most up-to-date browser; contact your IT if you continue to have issues viewing the PDFs.  

3/10/2026: Use MS Edge to access Chemwatch.  

Currently Firefox and Chrome are showing a blank screen when trying to view an SDS due to recent changes in university security settings, which may be incompatible with the older PDF plug-in used on those browsers. EHS is actively working to resolve this issue.  If you cannot access an SDS via the university's Chemwatch link, the 800 number is available to campus.
