Phast™ is a globally adopted solution for modelling discharge, dispersion, fires, explosions and toxic effects of a wide range of loss of containment scenarios.

Process safety professionals benefit from 40 years’ worth of development and validation by our industry experts and its continued use by more than 10,000 users across 1,000 organizations.

Phast is being used in diverse industries, including oil and gas, petrochemical, liquefied natural gas (LNG), pharmaceutical, hydrogen and ammonia, carbon capture and storage (CCS), insurance, academia, and public sector (governmental and regulatory bodies).

Phast software add-ons for in-depth analysis

Phast offers add-ons that enhance modelling capabilities and provide deeper insight into the consequences of complex scenarios.

Multi-Component (MC) add-on for advanced modelling of complex mixtures (e.g. two-phase releases).

Explosions add-on brings analysis of explosions in three dimensions, directional modelling effects and visualisation of combined effect contours.

Computational Fluid Dynamics (CFD) add-ons for modelling the impact of 3D geometries.

Evaluate key risk metrics for ALARP demonstration​

Individual and societal risk metrics are provided as standard: LSIR contours, FN curves and PLL.

Risk ranking points allow you to determine the risk at any location on your map and identify major risk contributors.​

With flexible ways to setup your study and perform sensitivity studies, it’s easy to evaluate the impact of risk reduction measures identified as part of your ALARP demonstration process.​

Risk-based design for cost-effective operations​

Why prevent the worst case consequence when it has a one in a million chance of occurring? ​

Many regulations around the world allow for risk-based design, where risks are mitigated in areas where it matters most.​

Safeti software supports easy identification of the highest risk contributors, so that meaningful mitigation measures can be proposed by your stakeholders and evaluated further for their risk impact.​

Move your QRA beyond a box-ticking exercise and take real action from your risk data.​
