Security PHA Review for Consequence-Based Cybersecurity

About Edward Marszal

Edward Marszal, Professional Engineer (PE) and ISA84 Safety Instrumented Systems Expert, is the president and chief executive officer at Kenexis, an engineering consultancy providing cybersecurity,  safety instrumented systems (SISs), fire and gas system (FGSs), and critical alarm system solutions to the process industries.

Marszal is a long-time practitioner and pioneer of the techniques and tools associated with technical safety and the performance-based design and implementation of instrumented safeguards. He began his career as an instrumentation and control field advisor at UOP, performing functional safety assessments of control systems and safety instrumented systems. He also designed and managed the development of custom control systems and SIS projects.

After leaving UOP, Marszal joined Environmental Resources Management (ERM), where he specialized in financial risk analysis and process safety management.

He then co-founded and joined exida, where he was responsible for helping users and vendors of industrial automation systems develop safety critical and high-availability solutions. Marszal specialized in performing numerous SIS safety life-cycle projects that included process hazard analysis (PHA) facilitation, Layer of Protection Analysis (LOPA) facilitation, safety integrity level selection, safety requirements specification development, start-up acceptance testing assistance (validation), and function test plan development.

After leaving exida, Marszal joined Kevin Mitchell in the founding of Kenexis, which was established to assist process industry users implement instrumented safeguards.

Marszal has been highly engaged in professional societies, and has been an active instructor and a prolific author throughout his entire career. In 1994, Marszal joined the ISA84 committee to help develop standards and technical reports and has been an active participant in the committee ever since.

He is the author of record for ISA’s EC52 Advanced Safety Integrity Level (SIL) Selection training course, which he frequently presents in combination with ISA’s EC54 Advanced Design and SIL Verification course. He is also the author of the award-winning ISA textbook, Systematic Safety Integrity Level Selection with Layer of Protection Analysis, the accompaniment to the EC52 training class.

Additionally, Marszal is the co-developer and frequent presenter of ISA’s EC56P Fire and Gas System Engineering: Performance-Based Methods for Process Facilities course. In addition to providing ISA training, Marszal also presents a large amount of Kenexis’ training offerings, which cover a range of instrumented safeguard topics.

He earned a BA in chemical engineering, with an emphasis on process controls and artificial intelligence, from Ohio State University.
