CAMEO Chemicals Software

Two sample screenshots from the CAMEO Chemicals mobile app showing a chlorine datasheet and a set of reactivity predictions for a chemical mixture.CAMEO Chemicals is the hazardous chemical database for the CAMEO® software suite, which is used widely to plan for and respond to chemical emergencies. CAMEO Chemicals also has a tool to predict possible hazards if chemicals are mixed together.

With CAMEO Chemicals, you can search through the extensive chemical database to find chemical datasheets with critical response information, including physical properties, health hazards, information about air and water hazards, and recommendations for firefighting, first aid, and spill response.

Additional datasheets based on UN/NA identification numbers provide response information from the Emergency Response Guidebook (ERG) and shipping information from the Hazardous Materials Table (49 CFR 172.101).

CAMEO Chemicals is available as a website, mobile website, mobile app, and desktop program. The mobile app (shown above) and the desktop program formats can be used offline, and the desktop program can share information with other CAMEO suite programs.
