SLAB View
Emergency Release Dense Gas Model
This software provides a graphical user interface for the SLAB atmospheric dispersion model, specifically designed for denser-than-air releases. It is an essential tool for predicting hazardous zones and assessing potential impacts of accidental emissions.
The platform visualizes how a release evolves over time and determines the total footprint of the incident.
Users can simulate continuous, finite duration, and instantaneous releases from four different source types:- A ground-level evaporating pool
- An elevated horizontal jet
- A stack or elevated vertical jet
- And a ground-based instantaneous release

SLAB View Key Features
The SLAB model was developed in the 1980's by the Lawrence Livermore National Laboratory (LLNL), with financial support from the Department of Energy (DOE). The SLAB model is currently distributed by the US EPA.
Integrated Interface
Fully integrated GIS-based interface combining easy to use graphical tools.
3D Visualization
Visualize plume dispersion in 3D with SLAB 3D's animation, ideal for presentations and analysis.
Google Earth Export
Export your buildings, sources, receptors and contours into Google Earth.
