Hi Shannon—

                We are a small college, Trinity College, in Hartford Connecticut.

                Depends on what you mean by inventory, and this is exclusively performed in our chemistry department.

                Daily we inventory all flammables, corrosives, acids and bases in each lab.

                Monthly we perform a data search using our inventory system of chemicals to see what has been disposed and purchased.  Strictly a computer search and run and then reading the results.  We also maintain this list as a breakdown by floor and lab so that if the need arises we can notify any first responders of what to be wary of in each lab.

                Yearly , typically in August when research labs shut down, we physically inventory each lab to also evaluate how much material is actually in each container and evaluate age of materials.

                And then when professors retire and we also inventory their lab and dispose of any out of date material.

                I hope this helps you a little.

                Good luck.
