The following table lists some of the most common chemicals which present a particularly severe risk to health (high toxicity chemicals). This list is of course not intended to be comprehensive, so don't assume that if a chemical does not appear on it, the chemical presents a negligible risk!
Web links to the properties of most chemicals (MSDS data) are provided. If
no link is given for the chemical in which you are interested, you can
try going to the
MSDS section of the
Safety Home Page of the
Physical and Theoretical Chemistry Laboratory at
Oxford University which contains
links to data on a large number of chemicals.
