We get MSDS on every substance and file there with our safety assessment.

is a good starting point to find MSDS.

I addition to paper copies of our assessments and lab protocols we have hyperlinked these on a networked drive.  This enables users to jump from the lab protocols directly to the safety information.

We have about 600 safety assessments for laboratory substances, all hyperlinked to an index, but we still have some way to go in linking ever reference to a substance, in the protocols, to the safety information.
