Modeling Software for EHS Professionals

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 BREEZE LFG Fire/Risk, EHS professionals can efficiently analyze the risks from a vessel or pipeline failure as required for regulatory compliance and safe operations. By incorporating a variety of sophisticated models – Source5 Model, DEGADIS Model, and Fire Models – users have more versatility and power!
