Overview Feature/Benefit Applicability FAQ
SLAB is ideal for determining toxic endpoint distances and distances to lower flammability limits (LFLs) for certain toxic and flammable chemicals in accordance with EPA’s Risk Management Program (RMP) requirements.

SLAB can be used to model continuous, finite, and instantaneous releases from evaporating pool, elevated horizontal or vertical jets, and instantaneous area or volume sources. Except for the evaporating pool sources, which is assumed to be all vapor, the remaining sources may be either pure vapor or a mixture of vapor and liquid droplets (aerosol). For each scenario, a user-specified averaging time is required.

SLAB is included in the BREEZE HAZ DISPERSION and BREEZE HAZ PROFESSIONAL product suites
