UNNA datasheets provide response information from the Emergency Response Guidebook and shipping information from the Hazardous Materials Table (49 CFR 172.101). In addition to the information on the datasheets, users can also add chemical datasheets to the MyChemicals collection to see what hazards might occur if the chemicals in the collection were mixed together.

All of the programs in the suite work interactively to share and display critical information in a timely fashion; the programs can also be used individually.

ALOHA (Areal Locations of Hazardous Atmospheres) is a hazard modeling tool used to evaluate the atmospheric dispersion of hazardous chemical vapors, as well as some fires and explosions.

ALOHA prompts the user to enter basic scenario information (such as weather conditions and details about how the chemical is escaping), and ALOHA will create a threat zone estimate of the area where a hazard (such as toxicity or thermal radiation) has exceeded a user-specified Level of Concern (LOC).

CAMEO is a database application (with eight modules) designed to assist with the data management requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA).

CAMEO Chemicals features an extensive database of chemical datasheets that provide critical response information, including physical properties, health hazards, air and water hazards, and recommendations for firefighting, first aid, and spill response.

Additionally, it also has a reactivity prediction tool that can be used to estimate what hazards (such as explosions or chemical fires) could occur if chemicals were to mix together.

MARPLOT (Mapping Applications for Response, Planning, and Local Operational Tasks) is a mapping program; users can quickly view and modify maps, and they can create their own objects to place on the maps.

ALOHA threat zones can be displayed on a map in MARPLOT, and objects on the map (such as facilities) can be linked to related records in the CAMEO program.

Tier2 Submit is an adjunct program in the suite, which allows users to complete EPCRA Tier II forms electronically.

The facility, chemical inventory, and contact information entered into Tier2 Submit can also be imported into the corresponding modules in CAMEO.

The suite includes four core programs: ALOHAxAE (a modeling application that estimates threat zones associated with hazardous chemical releases), CAMEO (a database application to assist with data management for emergency planning and response), CAMEO Chemicals (a database of hazardous chemical datasheets), and MARPLOTxAE (a mapping program).

Tier2 Submit is an adjunct program to the suite; it is used to complete Tier II forms electronically and that information can be imported into the CAMEO program.

Under UNEPs Awareness and Preparedness for Emergencies at the Local Level (APPELL) program, the CAMEO suite has been demonstrated or taught in 50 countries.

Users can also bypass ALOHAs calculations and provide their own source strength values for a gas using the direct source to describe a release directly into the atmosphere.

Depending on the release conditions, ALOHA can model several different types of scenarios: toxic vapor clouds, flammable area of vapor clouds, vapor cloud explosions, pool fires, jet fires, and Boiling Liquid Expanding Vapor Explosions (BLEVEs).

For dispersion scenarios, ALOHA models dispersion of both neutrally-buoyant (Gaussian) gases and heavier-than-air gases.

ALOHA only estimates one type of hazard for each scenario; the hazards modeled in ALOHA are toxicity, flammability, thermal radiation, and overpressure.

ALOHAs threat zone estimates are displayed on a grid in ALOHA or on a map in MARPLOT, and users can get information on the hazard level at a specific location using the threat point feature.

Users can save accident scenarios as ALOHA-readable files, then easily evaluate a variety of scenarios and archive results.

Contents of output windows can be readily transferred to documents and reports in word-processing or graphics applications.

The CAMEO program has eight modules: Facilities, Chemicals in Inventory, Contacts, Incidents, Special Locations, Routes, Resources, and Screening and Scenarios.

The first seven modules are a place for users to enter information about chemicals that are stored or transported in their communities, as well as information about locations that may need special attention during a chemical accident and resources that may be useful in a response.

The Screening and Scenarios module can be used to model potential threat zones as required under EPCRA.

Chemical datasheets provide physical properties, health hazards, information about air and water hazards, and recommendations for firefighting, first aid, and spill response.
