Comprehensive Accidental Release and Consequence Modeling Application

BREEZE Incident Analyst is a comprehensive tool for accidental chemical release hazard and consequence modeling. Featuring industry-standard toxic dispersion, fire, and explosion models that have been developed by U.S. government, military, and industry groups, Incident Analyst provides a robust capability to evaluate the threats posed by accidental hazardous chemical releases. Whether modeling for facility design/safety improvement purposes, a U.S. EPA Risk Management Program Offsite Consequence Analysis, real-time assessment of hazards in emergency situations, or reconstruction of a past incident, BREEZE Incident Analyst puts a suite of ten powerful models at your disposal, all wrapped in a user-friendly interface.

Product Tour

Incident Tab

The Incident Tab is the heart of the program - through this one tab the user can specify all of the critical information needed for a model run. Chemical information, meteorological data, source characteristics, and result options such as concentration averaging time and levels of concern can all be quickly entered in this intuitive section of the program.

Dispersion Models

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. Learn more


Fire Models

Model a wide range of conditions with four fire (thermal radiation) models. These include the Gas Research Institute (GRI) unconfined liquid pool, confined liquid pool, and jet fire models, as well as the U.S. EPA BLEVE (Boiling Liquid Expanding Vapor Explosion) thermal radiation model. All four models can calculate the thermal radiation level produced by the fire, including the radius within which a specified radiation level will be exceeded. Additionally, the BLEVE model provides the total... Learn more


Explosion Models

Calculate the blast overpressure created by vapor cloud explosions with the U.S. Army and HSE TNT Equivalency, TNO Multi-Energy, and Baker-Strehlow-Tang (B-S-T) models.  Scenario parameters can be incorporated into these models including proximity to ground level (ground reflection), density of obstacles, and vapor cloud flame speed.  Incident Analyst's explosion models make the conservative assumption of not modeling shielding from any specific structures.  For more advanced explosion modeling...

Chemical Database

BREEZE Incident Analyst includes a robust chemical database, containing essential information needed by its multiple models for a wide variety of common chemicals. From physical characteristics, such as boiling point and critical pressure, to exposure hazard levels, such as Immediately Dangerous to Life and Health (IDLH) concentration, Incident Analyst's database saves hours of time searching for data.

Source Term Wizard

Two of the most difficult parts of conducting air dispersion modeling for an accidental release case are calculating the proper source parameters to use and selecting the correct model to use.  BREEZE Incident Analyst's Source Term Wizard can complete both of these tasks, greatly simplifying your job.  With the Source Term Wizard, the user need only supply information that is commonly known: storage conditions such as storage tank size, shape, and temperature, and what type of accident is being... Learn more


Map Tab and Base Maps Tab

Import basemaps (image files, DXF files, and shapefiles) to speed up scenario setup and produce highly informative results graphics.  Rather than hunt down coordinates of every source and point of interest for modeling results, users can simply use the Map tab's point-and-click interface to add these objects to their modeling runs.  Additionally, model results can be quickly and easily output to Google Earth. Learn more


Results Tab

Incident Analyst provides a robust set of model outputs. A Results Summary file provides a quick look at the most critical results (e.g. radius of exposure to concentrations over a specified threshold). For those needing more information or an in-depth understanding of why the model produced a given result, the Model Results file provides detailed information. Users can have confidence in their understanding of their results thanks to the User Guide and extensive technical documentation on each... Learn more
