Arthur M. Dowell, III, P.E.
Arthur M. Dowell, III, P.E. Art is an independent chemical process safety consultant. He has 42 years industrial experience at Rohm and Haas (now owned by the Dow Chemical Company) in technical support to operations, engineering design, plant startup, research, technology management, hazard and risk analysis, and incident investigation. He is recognized in the industry for his work in process safety management systems, incident investigation, and risk assessment and has many years conducting incident investigations. Mr. Dowell has extensive experience leading PHAs (Process Hazard Analyses), and performing consequence analysis and fault tree analysis. He is a proficient user of FMEA, what-if/checklist, event trees, and, an emerging technique, HAZROP (Hazard Reliability, and Operability Analysis). He taught multiple internal courses for Rohm and Haas PHA facilitators. He was a co-developer of the Multiple Cause, Systems Oriented Incident Investigation System at Rohm and Haas in the 1980s, and has conducted numerous training courses on incident investigation within Rohm and Haas and for the industry overall. He has been using LOPA (Layer of Protection Analysis) for chemical processes for more than 20 years, spearheading its use in Rohm and Haas Company, publishing it in industry symposia, and mentoring and training engineers in its use. Mr. Dowell served several years on the ISA S84 Standard Committee and the US Technical Advisory Group for the IEC 61511 Standard Committee. He was one of the primary authors of technical report TR84.0.02 for analysis of the performance of Safety Instrumented Functions (SIFs). Mr. Dowell is a Fellow of AIChE and a member of ISA (the Instrumentation Systems and Automation Society). He served the South Texas Section of AIChE on the Executive Committee and as secretary and treasurer. He is a licensed Professional Engineer (Chemical Engineering) in both Pennsylvania and Texas.

Subject: "Layers of Protection Analysis (LOPA)-Another Tool in the PSM Arsenal"
In order to determine if shutdown systems (Safety Instrumented Systems -- or SIS as they are called today) and other independent layers of protection provide sufficient risk reduction, several companies and industry groups developed and applied Layer of Protection Analysis (LOPA) during the 1990s.LOPA is a simplified risk assessment tool that determines the risk reduction provided by such features as the basic process control, operator response, and relief devices to determine how much protection should be provided by safety instrumented systems.LOPA offers a consistent and cost-effective approach for this analysis and it has the added benefit of resulting in enhanced system documentation.Drawing from the experience of several companies and organizations, this talk provides an overview of LOPA and presents lessons learned from the application of LOPA over the past decade.Examples are given to avoid potential pitfalls and traps.
Art Dowell is a chemical engineering graduate of Rice University.He has 35 years experience at Rohm and Haas Company and is now Senior Technical Fellow, Hazard Analysis.He has participated in writing three books for CCPS (Center for Chemical Process Safety) on incident investigation, inherently safer processes, and layer of protection analysis (LOPA).He is an instructor for the AIChE layer of protection short course.Art is a member of ISA (the Instrumentation Systems and Automation Society), a Fellow of AIChE, and has received the Bill Doyle award from AIChE and the Albert Sperry Award from ISA.
