CAMEO Software

CAMEOfm home screen imageSince CAMEOfm 2.0, the traditional CAMEO® functionality has been split into two programs that need to be downloaded and installed separately:

  • CAMEOfm is a database application where you can keep track of information (such as chemical inventories and contact information for facilities in your community) to assist in emergency response and planning.  It is especially useful for managing data required under the Emergency Planning and Community Right-to-Know Act (EPCRA).  You can enter information into the CAMEO database manually and/or by importing a Tier2 Submit™ file (if the facilities and/or planners in your state use that program to complete Tier II forms under EPCRA).
  • CAMEO Chemicals has an extensive chemical database with critical response information for thousands of chemicals, and a tool that tells you what reactions might occur if chemicals were mixed together.

The programs can be used individually or in conjunction with other programs in the software suite, such as the ALOHA® hazard modeling tool and the MARPLOT® mapping program.  Learn more about the CAMEO software suite.
