DHS retained germanium tetrafuoride in the list of their Appenix A to Chemical Facility Anti-Terrorism Standards
USA DEPARTMENT OF HOMELAND SECURITY (DHS) retained germanium tetrafuoride in the list of their Appenix A to Chemical Facility Anti-Terrorism Standards Interim Final Rule, effective from 20 November 2007. Appendix A lists chemicals of interest and screening threshold quantities, or STQs. Any facility that possesses (or later comes into possession of) the listed chemicals in quantities that meet or exceed the STQ for any applicable security issue must complete and submit a Top-Screen. This will assist the Department in determining whether a facility presents a high level of security risk.
