IX. Chemical Inventories
A. Inventory of All Chemicals and MSDS Sheets in the Chemistry
Department
All incoming MSDS sheets for each and every chemical purchased for the Chemistry Department
are kept in a central area of the building in a set of orange-red binder notebooks. They are mailed from the
manufacturer of the chemical to Salem Hall.
As chemicals are unpacked in the Dockyard area, the packing slips are placed in a basket on the
wall next to the receiving table. The chemicals are dated in ink on the bottle label and taken to the
particular lab in the building where it is to be used, after entering the chemical and its MSDS sheet into the
on-line chemical inventory. The MSDS sheets are alphabetically arranged in the online inventory system
and a hardcopy of the MSDS inventory is kept in a black notebook near the actual the actual MSDS sheets.
These MSDS sheets are accessible 24 hours a day. The inventory web site is:

Presently, designated storage areas are assigned in each laboratory for storage of carcinogens and
teratogens/mutagens. Chemicals with a high degree of acute toxicity will be given an HMIS/NFPA acute
toxicity rating of 3 or 4 on the MSDS sheet by the chemical‟s manufacturer. Also “Select carcinogens” are
identified from manufacturer‟s MSDS data. There is at present only one universally acknowledged list of
known human teratogens. It is contained on page XXV of Shepard, Thomas H.,Catalog of Teratogenic
Agents, 8th edition, The Johns Hopkins University Press, Baltimore, MD: 1995. See
http://depts.washington.edu/~terisweb/teris/
They are listed below. Most of them are hormones or drugs:

Additional sources of possible teratogens or mutagens are listed on page 46 of Prudent Practices.
Until a definite, all-inclusive list of teratogens or mutagens is published, it shall be the practice of the
Chemistry Department to designate such substances in the MSDS inventory based on information contained
in the MSDS sheet and so rated in HMIS/NFPA format as defined previously.
