Emergency Release Dense Gas Model

SLAB View Overview

Software Category: Emergency Release

Version 5.2: Release Notes


SLAB View is a graphical user interface for the SLAB model - an atmospheric dispersion model for denser-than-air releases. SLAB View is an ideal tool to predict hazardous zones and potential impacts of accidental releases.


SLAB View is able to show you how the release develops over time, as well as what the total footprint of the release will be.

SLAB View can model continuous, finite duration, and instantaneous releases from four types of sources:

  • a ground-level evaporating pool
  • an elevated horizontal jet
  • a stack or elevated vertical jet
  • and a ground-based instantaneous release

The SLAB model was developed in the 1980s by Lawrence Livermore National Laboratory (LLNL), with financial support from the Department of Energy (DOE). The SLAB model is currently distributed and supported by the US EPA.
