BREEZE Hazardous / Toxic (Accidental) Release Models
BREEZE hazardous release software makes it easy for environmental and safety professionals to identify hazards associated with accidental releases, fires, and explosions and communicate about the potential impacts of those risks. This product line features the following industry-standard dispersion models:

For accidental atmospheric releases (dispersion):
The following models are included in the all-new BREEZE Incident Analyst.
- AFTOX – is a Gaussian puff / plume dispersion model that estimates concentrations downwind from accidental chemical releases where the dispersing plume has the same density as air.
- INPUFF – is a Gaussian puff model that simulates the atmospheric dispersion of neutrally buoyant or buoyant chemical releases. The model accounts for point sources and a release duration that is either finite or continuous.
- DEGADIS – is a dense gas dispersion model that estimates concentrations downwind from an accidental chemical release where the dispersing toxic or flammable substance is initially heavier than air. DEGADIS is also included in BREEZE LFG Fire/Risk.
- SLAB – is a dense-gas dispersion model used to estimate pollutant concentrations downwind from an accidental chemical release that is heavier than air.

For fires:
The following models are included in the all-new BREEZE Incident Analyst and BREEZE LFG Fire/Risk
- Confined Pool Fire – for fires that occur when liquid is ignited in a confined area such as a dike or a tank
- Unconfined Pool Fire – for fires that occur when an unconfined spreading pool of liquefied fuel gas ignites
- Jet Fire and BLEVE – for fires that result from the leak or rupture of a pipeline containing a compressed or liquefied gas under pressure

For explosions:
The following models are included in the all-new BREEZE Incident Analyst.
- U.S. Army TNT Equivalency and U.K. HSE TNT Equivalency – for surface or free-air bursts where the explosion is centered at a single location
- TNO Multi-Energy – for vapor cloud explosions where the model uses a series of sub-blasts corresponding to potential blast sources within the cloud
- Baker-Strehlow – accounts for the variability of the blast strength by expressing the explosion as a number of fuel-air charges, each with individual characteristics
