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 |
