BREEZE Incident Analyst provides safety professionals with a full suite of industry-proven toxic dispersion, fire, and explosion models and powerful tools for assessing threats to life and property due to accidental chemical releases.
For the full list of features and bug fixes, read the release notes above.
What's New in Version 1.3
- Updated Tatuk control library
- Upgraded to Access Database Engine 2013
- Overhauled the BREEZE Incident Analyst start page with a new informative layout
- Updated the Component One library to support operating BREEZE Incident Analyst via VNC
- Added Energy measure unit options (such as Joules, Calories, Btu etc.) in the Option menu
- Adopted the worst-case release scenario in the U.S. EPA Risk Management Program (RMP) guidance for offsite consequence analysis (OCA) as the default weather conditions in the Meteorological form
- Incorporated the latest modeling algorithm of continuous buoyant plume/stack release type in the AFTOX model to align with U.S. EPA AFTOX
- Added a feature to allow AFTOX to output maximum concentration at a specified height and time
- Implemented a function to transfer the Source Term Wizard evaporation pool calculation output to AFTOX model
- Increased the calculation resolution to improve the accuracy of maximum distance calculation for specific Level of Concern (LOC), which is a bug in the U.S. EPA AFTOX
- Incorporates established, proven models developed by the U.S. EPA, U.S. military and Coast Guard, and industry groups
- Utilize well-documented, widely-accepted models: understand what your model is doing rather than trusting proprietary “black box” models
- Achieve trustworthy results for a fraction of the cost and time of CFD systems
- Reduce or eliminate the need to hunt for chemical properties with built-in chemical database
- Shorten model setup and execution time with intuitive ribbon bar interface and scenario templates
- Includes BREEZE 3D Analyst for visualization of results, export to Google Earth, etc
Toxic/Flammable Gas Dispersion Models
- Model dense gas plumes and evaporating chemical pools with DEGADIS and SLAB
- Model neutrally-buoyant gas plumes, including moving sources, with AFTOX and INPUFF
- Simplify computation of release characteristics (e.g. exit velocity and temperature) when they are not explicitly known with the Source Term Wizard
- Translate results from raw concentrations to designation of safe and hazardous areas quickly with Level of Concern database (e.g. IDLH and PEL for toxic gases, LEL or LFL for flammable gases)
Fire (Thermal Radiation) and Explosion (Overpressure) Models
- Predict thermal radiation exposure and temperature rise with the unconfined pool fire, confined pool fire, vertical jet fire (flare), and BLEVE models
- Model vapor cloud explosions with Baker-Strehlow-Tang, TNO Multi-Energy, U.S. Army TNT Equivalency, and U.K. HSE TNT Equivalency models
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.
Meteorological data is critically important for many of the models in BREEZE Incident Analyst. The program can accept meteorological observation data, or the user can manually specify weather conditions. Additionally, Incident Analyst uses a single data form to collect all meteorological data inputs each of the individual models and selects the necessary data for each model internally. This unique feature saves time and simplifies the setup process.
Select mixtures or chemicals, view their properties, and make changes to properties easily. Want to see what the effects of a change in process gas composition would be? Make quick, on the fly modifications to run that test without altering the permanent chemical database. BREEZE Incident Analyst also provides a robust capability to add chemicals, create mixtures, and save tweaks to chemical parameters – for more information on this, see Chemical Database.
Know which model you want to use and the parameters of your accidental release scenario? Select your model in the Source form, plug in your model inputs, and you are ready to run. Not sure which model to use, or not sure how to calculate a release parameter? For dispersion cases, use our powerful Source Term Wizard to take the guesswork out of your scenario setup.
