Downloading, Installing, and Running CAMEO

Download CAMEOfm version 2.1

Important note for current CAMEO users: Installing a new version of CAMEO will overwrite the data in your current version of CAMEO. To ensure that your data is successfully transferred to the new version, download and read the instructions for updating to CAMEO 2.1 from a previous version.

Download the Program Components

Since CAMEO 2.0, the traditional CAMEO functionality has been split into two programs that need to be downloaded and installed separately.

CAMEO 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.

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 downloadable version can share information with other CAMEO suite programs; an online version is also available.)
