Revonda P. Tew
Mrs. Tew has more than 30 years of experience in the chemical industry, with expertise spanning process development, process engineering, and process safety management (PSM) and evaluation. She holds one U.S. patent and began her career with 10+ years of hands-on experience in chemical manufacturing operations.
In the early 1990s, Mrs. Tew led the PSM compliance initiative at a large chemical manufacturing facility, where she authored policies and procedures aligned with regulatory, industry, and corporate standards, and oversaw their successful implementation. She has also been actively involved in plant emergency response, serving both as a responder and as a member of incident command post teams.
A highly experienced PSM practitioner, Mrs. Tew is recognized for her practical, day-to-day application of PSM principles in operating facilities. Over the past 15 years, she has delivered more than 160 sessions of 1- to 3-day PSM overview and auditing courses. She has trained over 375 incident investigators and root cause analysts, more than 750 PHA leaders, and over 2,500 process safety, reliability, and auditing professionals, as well as numerous individuals in human error prevention. Mrs. Tew has also helped to customize training materials across a range of topics, including process safety, RBPS, PSM, MOC, PHA leadership, incident investigation, and operating procedures, and she regularly serves as an instructor in these areas.
Her technical experience includes participating in, leading, and documenting more than 90 Process Hazard Analyses (PHAs), conducting numerous Management of Change (MOC) risk reviews and approvals, leading and participating in incident investigations, performing or contributing to more than 80 PSM compliance audits and Risk-Based Process Safety (RBPS) assessments.
In addition to her technical work, she has experience in community relations and crisis management. Her involvement includes participation in Local Emergency Planning Committees (LEPC), service with her local Community Emergency Response Team (CERT), and volunteer work as a trainer with the “Together We Prepare” disaster preparedness program for the American Red Cross.
Mrs. Tew has contributed to the broader professional community, including delivering courses at the American Society of Safety Engineers (ASSE) Middle East Chapter conferences in Bahrain (2008 and 2010) and serving as a session chair at the AIChE Center for Chemical Process Safety (CCPS) conference in 2011.
She helped develop Chapter 9 (the only standard on how to perform PHA of non-continuous modes of operation) of Guidelines for Hazard Evaluation Procedures, CCPS/AIChE, 2008 (3rd Edition) – this is the definitive text on performing PHAs, using HAZOP, FMEA, What-If, and other methods; Mr. Bridges and Mrs. Tew were co-authors of the textbook.
For the past two decades, she has served as a consultant to the chemical and oil refining industries, providing on-demand PSM expertise and support. Mrs. Tew is widely regarded as one of the most experienced process safety professionals in the field, particularly for her hands-on expertise in implementing and sustaining effective PSM systems in operating facilities.
