  • Description:
    "A description of the conceptual and mathematical models that form the basis of the ALOHA computer application are described. ALOHA is designed for use during accidental chemical spills to help spill response professionals assess the risk to human populations associated with toxic air hazards, thermal radiation from fires, and blast effects. ALOHA is designed to provide a close upper bound to the threat distances associated with chemical spills of a scale typical of transportation accidents, with typical threat zones in the range of 100 to 10,000 meters. ALOHA is limited to hazards associated with chemical vapors or chemicals that become airborne. ALOHA includes an extensive library of chemical property data, and models to assess the rate at which a chemical is released from containment and vaporizes. ALOHA links source strength models to air dispersion models to estimate the spatial extent of airborne hazards. ALOHA uses a graphical interface for data entry, and display of results. Exposures to toxic chemical vapors, overpressure, thermal radiation, or areas where flammable gases are present are represented graphically and with a text summary"--Executive summary (page 1).
