The EPA’s Chemical Compatibility Chart provides a summary table of EPA-600/2-80-076 April 1980 A METHOD FOR DETERMINING THE COMPATIBILITY OF CHEMICAL MIXTURES. The chart gives names of chemical classes with which the chosen class is incompatible. Legend indicates "Consequences" that can be expected when mixing chemical wastes.
Another good source for chemical compatibility predictions is Cameo Chemicals: Database of Hazardous Materials. Office of Response and Restoration, National Ocean Service, NOAA. http://cameochemicals.noaa.gov/ (Accessed 08/04/2011).
This website provides:
Database of reactivity information for more than 5,000 chemicals and chemical mixtures. The database includes information about the special hazards of each chemical and about whether a chemical reacts with air, water, or other materials.
Permits virtual "mixing" of chemicals to find out what dangers could arise from accidental mixing.
Build a temporary list of chemicals and predict reactivity online.
