BREEZE Incident Analyst offers an array of established dispersion models developed by the U.S. EPA, U.S. military, and U.S. national laboratories. From lighter-than-air to dense gases and jet releases to evaporating chemical pools, Incident Analyst has a dispersion model that can address your accidental release scenario.

Dense Gas/Two-Phase

For dense gases and evaporating liquid pools, BREEZE Incident Analyst offers the DEGADIS and SLAB models.

DEGADIS, developed by the U.S. EPA, Gas Research Institute, and U.S. Coast Guard, provides dense gas and aerosol dispersion modeling from source types including jets.

SLAB, which was developed by the U.S. Department of Energy and Lawrence Livermore National Laboratory, is equipped to handle numerous dense-gas scenarios, including evaporating pool and jet releases.

Neutrally-Buoyant Gases

For neutrally-buoyant gases, BREEZE Incident Analyst includes the AFTOX and INPUFF models.

AFTOX, developed by the U.S. Air Force, models dispersion of neutrally-buoyant gas and evaporating liquid pool spills.

INPUFF, developed by the U.S. EPA, models dispersion of neutrally-buoyant gases from stack/jet sources. INPUFF is equipped to handle moving sources, deposition and settling, variable emission rates, and more.
