Additional Information

I have 15 years' experience as a refrigeration contractor, followed by 18 years' experience as a graduate engineer in industrial refrigeration ammonia and CO2 applications up to 5,000 TR. My engineering experience includes design and project management positions with a D/B contractor, a large food processor, an A&E firm (Deputy Director of the Food & Beverage Group) and my current consulting business. I'm registered as a PE in 11 states and have an NCEES Record. Current committee service includes the International Institute of Ammonia Refrigeration (Standards-CM and Government Relations-VM) and the American Society of Heating, Refrigerating and Air-Conditioning Engineers (Std 15, TC 10.1, TC 10.3 and TC 10.5; VM on all). I have revised portions of chapter 2 in the 2014 and 2018 editions of the ASHRAE Refrigeration Handbook and am completing calculations of CO2 piping capacities in chapter 3. My work with the Refrigerating Engineers and Technicians Association includes vice president of the Oakland, CA chapter, founder and first president of the Phoenix, AZ chapter and presentation of "Evaporator Leaks and Control Valve Selection" at the 2018 RETA National Conference. I have a wide knowledge of past and present mechanical codes, including the BOCA National MC, SBCCI Standard MC, ICBO/IAPMO UMC, California MC, IMC/IFC, IIAR 2, ASHRAE Std 15 and ASME B31.5. My previous legal work includes mechanical design review and code interpretation for OSHA PSM and EPA ammonia release cases. Disputes in this profession tend to fall into one of three categories: component function, system design/installation/operation and regulatory compliance. My mechanical and engineering backgrounds help resolve operational issues and my committee service provides logical solutions to legal situations. In cases that cannot be supported on sound engineering and/or regulatory bases, I can provide a comprehensive survey of such exposure for review.
