The following websites offer excellent information on issues pertaining to laboratory safety.

 Howard Hughes Medical Institute (HHMI) Laboratory Chemical Safety Summaries (LCSS’s) - This website contains readily accessible safety information on nearly 100 common chemicals used in instructional and research lab settings. Once you arrive at this website, click on the “Select an LCSS” link on the left menu bar to choose from the LCSS’s.
 U.S. Centers for Disease Control (CDC) – Biosafety in Microbiological and Biomedical Laboratories (BMBL), 4th Ed. The standard primer on proper biosafety technique and practice in the laboratory. It’s in a fairly east-to-use format online, although print versions are available at this site, as well.
 U.S. National Library of Medicine - Hazardous Substances Data Bank. A ridiculous amount of information on an extensive list of common and not-so-common chemicals. In addition to excellent chemical safety information, various information can be found such as toxicity mechanisms and environmental standards for the chemical in question. To get started, just type in the chemical’s common name (or IUPAC name) in the HDSB search prompt.
 Sigma-Aldrich Corporation - Need MSDS’s? Looking for general safety information on a given chemical? If you can’t find it in HDSB (see above), then try out this site. You will need to exert a little more effort in tracking down the information; for every chemical information search the search engine will return about one useful result and thirty useless ones.
 University of Maryland – Glove Compatibility Chart. An excellent, compact resource for determining whether or not a particular glove is adequate for use with the given chemical. This is the most extensive compatibility chart I’ve found thus far.
 Honeywell Corporation – Hydrofluoric Acid (HF) Safety. A very handy website for determining safety procedures required for using HF in your lab.
 GFS Chemicals – Perchloric Acid Safety. An excellent document for determining safety procedures required for using perchloric acid in your lab. You must have Adobe Acrobat Reader to view this document.
