Metals Analysis Results for the Structural Qualification Test Series (SQTS) 01 - 05.

PDF Version Also Available for Download.

Description

Enclosed is the report summarizing the metals analysis results at the Contained Firing Facility (CFF), during SQTS 01 - 05. This metals analysis includes evaluation of a bulk dust and surface swipe sampling protocol during the testing series that obtained samples at 3 primary locations in the CFF chamber area. The sampling protocol for each of the bulk dust samples involves an assessment of the concentration for 20 different metals, the oxidation state of selected metals, a particle size selective analysis, and morphological information. In addition, surface swipes were taken during SQTS 05 on the equipment and personnel door frames ... continued below

Description

Enclosed is the report summarizing the metals analysis results at the Contained Firing Facility (CFF), during SQTS 01 - 05. This metals analysis includes evaluation of a bulk dust and surface swipe sampling protocol during the testing series that obtained samples at 3 primary locations in the CFF chamber area. The sampling protocol for each of the bulk dust samples involves an assessment of the concentration for 20 different metals, the oxidation state of selected metals, a particle size selective analysis, and morphological information. In addition, surface swipes were taken during SQTS 05 on the equipment and personnel door frames to indicate the characteristics of airborne metals due to leakage past the gasket seals. The bulk dust metals analysis indicates a nearly complete conversion of the aluminum casing to an oxide form with an even split between spherical and non-spherical morphology. Size selective analysis shows 83% of the particulates are in the inhalable size range of less than 100 microns and 46% are in the respirable range of less than 10 microns. Combining metals analysis and leakage results indicate the potential for a problematic personal exposure to metals external to the chamber unless modifications are made.
