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.
Levels of Concern and Averaging Times
Incident Analyst provides a robust ability to adjust model output parameters to suit your needs. Levels of concern can be specified based on the application’s database of thresholds, such as IDLH, PEL, and LFL, or based on a user-specified value, to determine a hazard zone appropriate for your release. Averaging times can be similarly adjusted to suit the particular chemical and situation you are dealing with, from concerns about 8-hour exposure levels to the few seconds of concentrations above LFL needed to ignite a fire or explosion.
