(updated 03/14/02) Instructions: This document is very long. Rather than scrolling through the pages to determine if FAU EH&S has the MSDS you are looking for, you may use the Acrobat Find Function (the "binocular "icon). Type in the name or part of the name of the chemical you are looking for. If you know the chemical 's CAS number you may type that in the Find box also. If you are associated with Florida Atlantic University, you may request a copy of an MSDS by sending an email to [email protected] or by calling EH&S at 7-3129.
