Approaches for identifying, characterizing and managing risks from accidentally released toxic gases

Accidental releases of toxic gases used by in semiconductor device and photovoltaic cell manufacturre and in other industries may present hazards to occupational or public health. Identification of consequences associated with such releases and characterization of accident-initiating events requires detailed and systematic evaluation. Many approaches are available to the semiconductor and photovoltaics industry to identify, characterize and manage risks from toxic gases. Application of these approaches may require simple data collection activities or complex evaluation efforts. The more complex efforts should only be initiated when screening efforts have shown that the activity of interest can present a significant hazard to life or property. Application of these approaches throughout the design and operation of these facilities, can improve plant safety. 16 refs., 3 figs., 2 tabs.
