Source5 – LFG-specific model developed by the Gas Technology Institute that predicts the vaporization rate from instantaneous spills and continuous leaks over land or water.

DEGADIS – EPA approved dense-gas model that predicts downwind vapor concentrations for explosion hazards

Fire models – developed by the Gas Technology Institute to calculate thermal radiation flux associated with a potential explosion and fire, including confined pool fires, unconfined pool fires, jet fires, and BLEVEs.

Integrated BREEZE productivity tools also enables users to perform:

• Receptor Analysis – Calculate the concentration time-history at single or multiple receptor locations
• Parametric Analysis – Visualize how variations in input parameters will affect the plume dispersion in DEGADIS

BREEZE LFG Fire/Risk is easy to use and quick to run. The intuitive interface guides the user through entering required and optional inputs and selecting the appropriate algorithms. With LFG Fire/Risk, EH&S professionals can efficiently analyze the risks from a vessel/pipeline failure as required for regulatory compliance and safe operations.

LFG Fire/Risk User Features:

• Imports AutoCAD .DXF, Windows .BMP files, and .JPG files
• Instant visualization of model results: 2-D contour plots, charts, and text summary reports
• Scenario management for developing “what-if” scenarios involving specific meteorological conditions and source parameters
• Customizable display and toolbars Online documentation, sample applications, and technical appendices
• Windows Explorer-type interface Compatible with Microsoft Excel cut/paste options
• GIS Interface
