This
paper provides a comparison of historical data from silane gas tests
performed in the 70s and 80s with more recent test data. The bulk of
the historical testing was performed by HRC under contract to IBM.
More recent tests have been performed by Union Carbide and Factory
Mutual Research Corporation/SEMATECH in the 90s. Ongoing tests of
large scale field releases are currently being performed by the
Compressed Gas Association. The paper first addresses the types of
ignition associated with silane releases, followed by a discussion of
silane releases in enclosures such as gas cabinets. This discussion
includes the effects of cross-flow ventilation requirements as
prescribed by National Fire Protection Association (NFPA) code.
Recommendations based on the latest
experimental information are provided for releases in enclosures.
Next, experiments regarding large external field releases of silane
are reviewed. Finally, a review and evaluation of the available blast
overpressure predictive methodologies is provided, and
recommendations regarding their applicability and use are given.
