Configured to meet your needs
Phast is available in a number of modes, from consequence analysis only to full risk analysis and extensions are available to increase the functionality within each mode.

Phast Consequence
Phast Consequence provides comprehensive hazard analysis capability, examining the progress of a potential incident from the initial release to its far-field effects. After you have identified your major hazards, Phast consequence allows you to predict all possible complex consequences from releases of hazardous material. It includes a wide range of models for discharge and dispersion as well as flammable, explosive and toxic effects.

Phast Risk
Phast Risk allows you to combine the consequences from each scenario in your QRA model, with their likelihood, to quantify the risk of fatalities. It is designed to perform all the analysis, data handling and results presentation elements of a QRA within a structured framework. Based on effects calculations and population
vulnerabilities, Phast Risk can integrate over all scenarios and weather conditions to estimate the total risk. Risk metrics, such as individual and societal risk, are generated by Phast Risk across your facility and surrounding area using the classical QRA methodology. Risk can be ranked at points of strategic importance
to show the relative influence of the various failure scenarios and their contribution to both individual and societal risk metrics. A key benefit of Phast Risk is the ability to identify major risk contributors and differentiate these from incidents with worstcase consequences which might otherwise dominate the safety review. Phast Risk helps you direct time and effort for mitigating your highest-risk contributors.

Phast extensions
The Financial Consequence extension helps you estimate the cost of a release of a particular material under specified conditions. The Financial Risk extension helps you calculate broader financial risks associated with accidents and can be used to help manage your business risk and assess appropriate levels of insurance. The Multi-Component extension provides greater accuracy for liquid or two-phase mixture releases compared to the standard pseudo-component approach.
