Hello again Mark,
Thanks for your interest in CAMEO.
CAMEO stands for the Computer-Aided Management of Emergency
Operations, a software program designed by federal government agencies
to assist emergency responders in dealing with chemical emergencies.
As such, CAMEO contains a wealth of information on the properties of
Since firefighters ordinarily use water to douse a fire, some of the
key information in CAMEO deals with water-reactive chemicals - those
substances that react violently with water, and hence, should be
treated with extreme caution in the presence of water.
Unfortunately, though, the CAMEO database is designed with some
built-in limitations on how readily information can be downloaded or
printed out (I'm not sure why this is, but it may be due to licensing
restrictions imposed by private-sector suppliers of information to the
CAMEO system). Hence, I cannot provide you here the full list of
water-reactive chemicals, even though I can see it clearly on my
computer screen. However, I can certainly provide you instructions
for generating the list for yourself.
General information on CAMEO can be found at the system's main website
maintained by the US Environmental Protection Agency:
and the general description of the CAMEO system is:
CAMEO is a system of software applications used widely to plan for and
respond to chemical emergencies. It is one of the tools developed by
EPA?s Chemical Emergency Preparedness and Prevention Office (CEPPO)
and the National Oceanic and Atmospheric Administration Office of
Response and Restoration (NOAA), to assist front-line chemical
emergency planners and responders. They can use CAMEO to access,
store, and evaluate information critical for developing emergency
plans. In addition, CAMEO supports regulatory compliance by helping
users meet the chemical inventory reporting requirements of the
Emergency Planning and Community Right-to-Know Act (EPCRA, also known
as SARA Title III). CAMEO also can be used with a separate software
application called LandView ® to display EPA environmental databases
and demographic/economic information to support analysis of
environmental justice issues.
The CAMEO system integrates a chemical database and a method to manage
the data, an air dispersion model, and a mapping capability. All
modules work interactively to share and display critical information
in a timely fashion. The CAMEO system is available in Macintosh and
As you can see, CAMEO includes a good deal of capabilities (plume
modeling, mapping, etc) that are probably not relevant to your needs.
However, the main chemicals database -- with the reactivity
information included -- is right on target.
The actual download for CAMEO is here:
Select the appropriate file for your system -- the Windows version is
a 34.8 megabyte download.
Once downloaded, start the system from your "Programs" list, and
you'll open up to the main CAMEO page with several options.
Click on the "Search for a Chemical" option, and you'll open up a new
window for the "CAMEO Basic Search" page. On the pull-down menu
entitled "Reactive Hazards" select "Water Reactive". Leave the rest
of the search options blank, and select "Search".
This should open up a list of 559 chemicals that are water-reactive.
By clicking on a chemical name, you'll be taken to (yet another) page
with deatiled information about the chemical. Note two things here.
One, is that one of the tabs on the page is labelled "Reactivity", and
will provide you detailed information about reaction events,
by-products, etc. for the listed chemicals. Secondly, at the top,
right-hand side of the page is a forward-facing arrow...pressing this
will advance you to the next chemical on the list.
Finally, at the top left of the page is a button labelled "List" that
will return you to the full list of 559 chemicals.
I hope this information fully meets your needs. But if you have any
questions about CAMEO, please let me know before rating this question.
Just post a Request for Clarification, and I'll be happy to assist
All the best.
search strategy: I knew about CAMEO, and conducted a Google search on
[CAMEO EPA ] in order to locate the homepage for this database.
