A small version of the ALOHA icon. ALOHA
Overview of ALOHA, a modeling program that estimates hazards (toxicity, flammability, thermal radiation, and overpressure) after a chemical release.
ALOHA Arc Tools
Tools you can download to import an ALOHA threat zone into ArcView 3.x or ArcMap 8.x or 9.x.
ALOHA's Limitations
Even when you provide the best input values possible, ALOHA (like any model) can be unreliable in certain situations, and it cannot model some types of releases at all.
Ask Dr. ALOHA
List of articles about ALOHA. Articles include discussions of key program features and sample ALOHA scenarios.
 CAMEO
Overview of CAMEO, a database application for hazardous chemicals. Search for response recommendations in the chemical library, predict hazardous reactions, and manage EPCRA data.
Sketch of several chemical vials. CAMEO Chemicals
An easy-to-use, online tool for emergency responders and planners. Use this free Web site to search for chemicals, get response recommendations, and find out how chemicals would react if they mixed.
Small image of a chemical responder in protective gear. CAMEO Software Suite Programs
Tools for emergency responders and planners, including CAMEO, CAMEO Chemicals, ALOHA, and MARPLOT.
CAMEO Toolkit
Tools and information for CAMEO, ALOHA, and MARPLOT users, including frequently asked questions, help aids, and links to Web resources.
CAMEO Training
Information about CAMEO training, the instructor certification program, and schools that are using CAMEO programs to teach students about emergency response and planning.
A small LandView image. LandView
Overview of LandView, a geographic data viewer that uses MARPLOT maps.
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.
A small version of the MARPLOT icon. MARPLOT
Overview of MARPLOT, CAMEO's mapping program. Create, view, and modify maps.
MARPLOT Maps
Description of the kinds of maps that MARPLOT can use.
People Using CAMEO
Discussion of some of the ways people use CAMEO.
Public Exposure Guidelines
Overview of AEGLs, ERPGs, and TEELs and how ALOHA uses these public exposure guidelines as Levels of Concern when modeling a toxic chemical release.
RMP*Comp
Overview of RMP*Comp, a program that helps chemical facilities that fall under the Risk Management Planning (RMP) rule complete their required offsite consequence analysis.
icon for chemical reactivity worksheet. The Chemical Reactivity Worksheet
The Worksheet is a free program you can use to find out about the reactivity of substances and mixtures of substances. Version 1.9.2 is now available for download.
Threat Zones and Other Output
Discussion of output from the ALOHA hazard model: threat zone plot, text summary, threat at a point, and source strength.
A small version of the Tier2 Submit icon. Tier2 Submit
Overview of Tier2 Submit, a software program developed to provide assistance to people who file Tier II reports under EPCRA. Tier2 Submit is fully compatible with CAMEO.
Working with ALOHA
Brief explanation of how ALOHA helps you get the hazard model information you need quickly during an emergency response.
Working with MARPLOT
Discussion of MARPLOT concepts, including map objects, layers, searching, and sharing data with CAMEO.
Workplace Exposure Limits
These limits (such as IDLHs, TLVs, PELs, and RELs) are intended to protect workers from excessive exposure to toxic chemicals in the workplace.
