The BREEZE Incident Analyst Chemical Database includes over 150 preexisting chemicals that users can select from for their accidental release modeling scenarios. To view all of the chemicals available in the Chemical Database, users can select the Chemical button in the Incident Tab or click More Options in the Chemical Tab of the Scenario settings. In addition to being able to select from these preexisting chemicals, users have the ability to edit preexisting chemicals and add new chemicals and chemical mixtures to the BREEZE Incident Analyst database.

To learn how to successfully add a new chemical mixture to the database, please follow the steps below:

  1. Click the Chemical Database button in the Incident Tab.

    Chemical Database - BREEZE Incident Analyst

  2. A new Database tab will appear in the Ribbon Bar. Click the Add New Mixture button.

    Add New Mixture - BREEZE Incident Analyst

  3. In the Chemical window that opens, you will be prompted to enter the ID, Name, CAS Number, Component basis (i.e., mole- or mass-based), and material components of the mixture. Enter this data for your mixture.
  4. Once the data have been entered, click Calculate Average Properties. Using these components, BREEZE Incident Analyst will automatically calculate estimated properties of the mixture. 
  5. A message will appear stating “Mixture properties have been changed. Do you want to update the chemical properties?” Click Yes.
  6. Click OK. Another message will appear confirming that you want to make this change in the Chemical Database. Click Yes if you are sure. Note: It is important to point out that by following the steps below, you will be making permanent changes to the Chemical Database. Unlike changes made in the Chemical Tab, changes made in the Chemical Database cannot be undone once the changes are saved.

Your new chemical mixture will be added to the database and available for use in your accidental release modeling scenarios moving forward.
