Davis, D., G. DeWolf, J. Quass, AND M. Stohs. PREVENTION REFERENCE MANUAL: CHEMICAL SPECIFIC. VOLUME 12. CONTROL OF ACCIDENTAL RELEASES OF SULFUR DIOXIDE. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/8-87/034L.
Description:
The report discusses the control of accidental releases of sulfur dioxide (SO2) to the atmosphere. SO2 has an IDLH (immediately dangerous to life and health) concentration of 100 ppm, making it an acute toxic hazard. Reducing the risk associated with an accidental release of SO2 involves identifying some of the potential causes of accidental releases that apply to the processes that use SO2. The manual identifies examples of potential causes and measures that may be taken to reduce the accidental release risk. Such measures include recommendations on: plant design practices; prevention, protection, and mitigation technologies; and operation and maintenance practices. Conceptual cost estimates of possible prevention, protection, and mitigation measures are provided.
