Prevention Reference Manual: Control Technologies. Volume 2. Post-Release Mitigation Measures for Controlling Accidental Releases of Air Toxics

摘要

The report covers post-release mitigation measures to control accidental releases of air toxics. This can be accomplished by a variety of mitigation measures that can contain, capture, destroy, divert, or disperse the released chemical. Mitigation measures begin with the initial siting and layout of a facility to decrease the area that would be affected by a release. The extent of the area potentially affected, the concentrations of toxic chemicals reaching those areas, and the duration of exposure can be estimated by vapor or gas dispersion modeling. The extent and magnitude of an actual release can be determined using meteorological instruments. Other measures involve the use of various mitigation techniques. The general application costs of these methods are discussed.
