Emergency responders (as well as programmers developing tools for use with the CAMEO software suite) can find an assortment of helpful guides, software tools, and training information for addressing accidents involving the release of hazardous substances.

ALOHA Example Scenarios

To build your knowledge of ALOHA and MARPLOT, download this training document and work through three step-by-step fictional ALOHA example scenarios.


Get to know ALOHA better by reading this series of informational articles that discuss key program features and walk through sample ALOHA scenarios.

Levels of Concern

In ALOHA, an LOC is a threshold value of a hazard (toxicity, flammability, thermal radiation, or overpressure); it's usually the value above which a threat to people or property may exist. For example, toxic LOCs (such as AEGLs, ERPGs, TEELs, and IDLHs) tell you what level of exposure to a chemical could be harmful if you breathe it in for a period of time.

ALOHA ArcMap Import Tool

To display ALOHA's threat zone predictions on a map, you can use MARPLOT (the mapping program for the CAMEO software suite), or you can also display threat zones in Esri's ArcMap using the ALOHA ArcMap Import Tool.

FOSC's Guide to NOAA Scientific Support

This publication, for oil and chemical spill responders, describes the products and services that the NOAA Scientific Support Team can provide to Federal On-Scene Coordinators (FOSCs).

ALOHA Technical Resources

If you are interested in developing a program or tool to work with ALOHA, here are a few useful documents to review.

CAMEO and its Uses

Discover who is using the CAMEO software suite and how they are adapting its programs for applications beyond chemical emergency response and planning.

CAMEO Training

Each year, thousands of first responders and emergency planners are trained to use programs in the CAMEO software suite in classes led by more than 100 CAMEO-certified instructors.
