CAMEO Chemicals

About this app

CAMEO Chemicals is a database of hazardous chemical datasheets that emergency responders and planners can use to get response recommendations and predict hazards (such as explosions or toxic fumes). This app runs offline.

Key Program Features:

• Search by name, CAS number, or UN/NA number to find chemicals of interest in the extensive database of thousands of hazardous substances. Includes "type ahead" feature for simplified chemical name searches. An advanced search with additional search criteria is also available.

• Review chemical datasheets for physical properties; health hazards; information about air and water hazards; recommendations for firefighting, first aid, and spill response; and regulatory information.

• Get information from additional sources using the U.S. Coast Guard CHRIS manual, the NIOSH Pocket Guide, and International Chemical Safety Cards links on many chemical datasheets.

• Access UN/NA datasheets for response information from the Emergency Response Guidebook (ERG) and shipping information from the Hazardous Materials Table. ERG Response Guide PDFs are available in English, Spanish, and French.

• Predict potential hazards that could arise if chemicals were to mix.

• Get offline access: the app runs without an internet connection. You can search for chemical and UN/NA datasheets, view ERG Response Guide PDFs and U.S. Coast Guard CHRIS PDFs, create MyChemicals collections, and view reactivity predictions--all while you're offline. When you're online, you can also go to additional resources on external websites (such as the NIOSH Pocket Guides and the International Chemical Safety Cards) from the app.

CAMEO Chemicals is developed jointly by the National Oceanic and Atmospheric Administration (NOAA) Office of Response and Restoration in partnership with the Environmental Protection Agency (EPA) Office of Emergency Management. It is one of the core programs of the CAMEO software suite (https://response.restoration.noaa.gov/cameo).

Note: Some extra permissions on your device are required for the app to generate PDFs (and other export files that you can share with others) and import files shared from the website, desktop, and app versions of CAMEO Chemicals. If you choose to disable the permissions, you will not be able to use the app's sharing or import features.

Ratings and reviews

The NEWEST VERSION 2.8 is easy to use. The wealth of information at my fingertips will help me and my responders make quicker and better informed decisions when working with HAZMATs. We can begin our IAPs quicker and mitigate an incident in record time. This is a MUST HAVE APP! If you have problems, go to their help site. A great tutorial.

Latest update won't open on older Android devices (e.g., Galaxy s5). This app, if you can open it, is a go-to HazMat incident resource for first responders. It's too bad the developers didn't legacy older versions of the Android OS in their latest update... s5 is only 3 - 4 years old. (HazMat specialist & instructor)

Excellent information for first responders in the field. ERG tied to newest version with a mapping component. Has been utilized successfully by our teams in NC
