  • Method and apparatus for pyrophoric and other type gas line explosion suppression
    Patent number: 6632261
    Abstract: A flash arrestor applicable to suppress explosions in gas lines generally, but specifically appropriate for suppressing explosions of pyrophoric gases, particularly silane in connection with integrated circuit manufacturing, has two identical flash suppression assemblies that are interconnected and act bidirectionally so as to suppress explosions occurring on either side of the apparatus. The positioning of a poppet relative to a poppet seat can be set manually into “open,” “closed” and “armed” positions, the latter indicating that the apparatus has been configured so as to intercept automatically any explosion that is transmitted to it through a gas line so as to yield a valve “closed” configuration, and that closed position can then be locked in manually.
