EMERGENCY RELEASE MODELS
SLAB is an atmospheric dispersion model for denser-than-air releases developed by the Laurence Livermore National Laboratory. Four types of releases can be treated by the model: a ground-level evaporating pool, an elevated horizontal jet, a stack or elevated jet, and an instantaneous volume source.
