    About the Instructors

    JOEL STOLZFUS has been a project manager for ignition and combustion of materials in oxygen-enriched environments at NASA's White Sands Test Facility (WSTF) since 1980. He is one of the developers of this ASTM course and has been teaching it since its inception in 1989. He has developed several tests to determine the suitability of metals in oxygen systems, including promoted combustion, frictional heating, and particle impact. He is also coeditor of related ASTM books, author of many papers on the ignition and combustion of materials, and an author in the National Fire Protection Association's Fire Protection Handbook.

    BARRY E. NEWTON, accident reconstructionist and forensic analyst for Wendell Hull and Assoc., knows all aspects of oxygen system design. He was previously with NASA WSTF, and has written over 50 oxygen component qualification test reports for WSTF and Johnson Space Center, including 19 NASA special project test reports on oxygen compatibility. He has authored several papers in the ASTM STP series on Flammability and Sensitivity of Materials in Oxygen Enriched Atmospheres, and is an experienced short course instructor.

    ELLIOT FORSYTH is a technical consultant for Wendell Hull and Associates, Inc. and the owner of Oxygen Safety Consultants. He performs hazards and failure analyses on oxygen systems and components, as well as consults on engineering design of oxygen systems and training of oxygen system operations. He is a former project engineer and leader of the oxygen hazards group at the NASA WSTF where he was involved in test system design and development for evaluating materials and components for use in oxygen systems. Forsyth has published papers on contaminant ignition in breathing-gas systems, particle impact ignition and fire extinguishment in oxygen environments.

    TED STEINBERG is a Senior Lecturer at the University of Queensland and a consultant to several international and domestic aerospace organizations including NASA, Rockwell, and Allied-Signal. He has co-edited three books and authored numerous papers on the flammability and sensitivity of materials in oxygen-enriched environments under both normal gravity and reduced gravity conditions. Steinberg has a B.S., M.S., and Ph.D degrees in mechanical engineering from New Mexico State University.

    STEPHEN D. HERALD is senior engineer for InfoPro Corporation in Huntsville, AL. He has worked for the past 13 years as lead product development engineer and department manager for various industries and is currently the lead engineer for the Materials Combustion Research Facility at NASA's Marshall Space Flight Center. Herald holds a BSME from University of Kentucky, Lexington, KY where he was vice-president of the ASME local Chapter.

    STEPHAN PERALTA, of Honeywell Technical Services Inc., is a project engineer in the oxygen hazards analysis group at NASA WSTF. He has been involved in the design and development of test systems for evaluating materials and components for use in oxygen systems. His work has included developing frictional heating and shear fracture tests of materials in liquid and gaseous oxygen and developing an oxygen hazards analysis database for NASA. He has authored or co-authored over 100 oxygen hazards analyses using the data and methods presented in this course.

    SAMUEL "EDDIE" DAVIS works for NASA and is the technical expert for oxygen systems at the George C. Marshall Space Flight Center in Huntsville, Alabama. He has worked with oxygen systems since 1987, focusing primarily on the safety of high-pressure oxygen systems for space vehicle applications.

    KYLE SPARKS of Jacobs Technology Inc. is a mechanical engineer, project lead, and the Oxygen Compatibility and Test Team group leader at NASA WSTF. He has been involved many aspects of material flammability and ignition testing and has worked extensively as an analyst performing oxygen compatibility assessments ranging from small facility components to high-flow turbo machinery. He has authored and co-authored several oxygen related technical papers and is active in both writing and updating ASTM standards. In addition to teaching the ASTM TPT oxygen courses he is also an instructor for a variety of oxygen related safety courses within the NASA community.
