SCOTT HELLSTROM, P.E.

Principal Engineer

Mr. Hellstrom has over 27 years of design and safety engineering experience which he applies to system safety and hazard analysis. He has over 20 years experience in the safety analysis and certification of every type of semiconductor and photovoltaic manufacturing equipment to industry and SEMI Standards. He specializes in mechanical hazards analysis, seismic analysis, hazardous waste tank analyses, and analysis of chemical distribution systems including analysis of equipment for installation Class 1, Division 2 locations. He also supports electrical certification and field labeling of equipment. His analyses techniques experience include Fault Tree, HAZOP, and Failure Mode and Effects Analysis (FMEA). Mr. Hellstrom is a Registered Mechanical Engineer in the State of California.

Project History

Specialty in safety evaluations of semiconductor and flat panel manufacturing, and other industrial equipment design using design guidelines and standards such as SEMI S2, NFPA 79 (Electrical), ANSI Z535.4 (Warning Labels), EN 60204-1 (Electrical) for CE Marking and the Essential Health and Safety Requirements of the Machinery Directive (2006/42/EC) Provided guidance and designed hundreds of hazard warning labels for equipment and warnings for system manuals as a result of hazard risk assessments. Equipment experience includes: Photolithography, ion implant, wet process, CVD, Etch, Vertical and Horizontal furnaces, Metrology, SIMS, SEMS, wafer analysis equipment, gas cabinets, stockers, and chemical mixing and delivery systems.
Performed and supported hundreds of 3rd party electrical certifications for semiconductor manufacturing, photovoltaic (PV), and other industrial equipment.
Performed over 75 seismic anchoring analyses per 1997 UBC requirements
Performed Hazardous Waste Tank Assessments per California regulations (Title 22)
Analyzed exhaust ventilation requirements for toxic and flammable chemical gas and vapor releases.
Performed safety evaluations of wind turbine designs
Supported review of MSDS and chemical container labeling for a leading chemical supplier
Performed stand alone fire risk assessments to SEMI S14

LONGLY LEWIS SAGENDORPH IV, BSME

Principal Engineer

Mr. Sagendorph has over 32 years of mechanical design and safety engineering experience. He has directed and coordinated Critical Design Reviews (CDRs) and reviewed the design and analysis efforts of outside engineering firms for guidance to internal and customer inquires. He has performed systems safety and hazard analysis evaluations of products in environmental, semiconductor, medical devices, and other industries. He also has performed numerous SEMI S2 safety evaluations, S8 Ergonomic Assessments and S10 Hazard and Risk Analyses to document the safety of machinery and the type of engineering and administrative controls required minimize risk. He is very knowledgeable of the applicable codes and requirements to supports electrical compliance audits and testing, electrical certification and field labeling of equipment. He has also performed safety analyses of equipment per the Essential Health and Safety Requirements of the Machinery Directive (2006/42/EC) and evaluation and testing products to EN 60204-1, to demonstrate compliance to the Low Voltage Directive (73/23/EEC).
