To help responders, who often face situations where more than one chemical may be involved in a spill scenario, the Chemical Reactivity Worksheet has been developed. It can be found on the web at: http://response.restoration.noaa.gov/chemaids.html, or at http://response.restoration.noaa.gov/chemaids/react.html. This can be downloaded from the Internet. It includes a database of reactivity information for more than 4,000 common hazardous chemicals. The database includes information about the special hazards of each chemical and about whether a chemical reacts with air, water, or other materials. It also includes a way for you to virtually "mix" chemicals to find out what dangers could arise from accidental mixing.
