Process safety is not just what we do—it’s who we are.



Mike and the team he works with at Bluefield Process Safety provide safety lifecycle consulting to the chemical process industries, both by working with industrial clients and by training others to do that work.  His expertise includes facilitating HazOps and other forms of Process Hazard Analysis, facilitating Layer of Protection Analysis, working with organizations to establish Risk Tolerance Criteria, developing Safety Requirements Specifications for Burner Management Systems and other Safety Instrumented Systems, performing SIL verification calculations, and assisting with PSM compliance.

With a career in the CPI that began in 1977 with Union Carbide, Mike was profoundly impacted by the 1984 tragedy in Bhopal and has been working on process safety ever since.  Mike founded Bluefield Process Safety in 2008.  Since 2009, he has been on the faculty at Missouri University of Science and Technology in Rolla, Missouri, where he teaches undergraduate courses on safety engineering and process risk management, training almost a hundred engineering students every year.

Mike writes blogs on process safety and frequently publishes and presents articles and papers on process safety, particularly in the areas of Process Hazard Analysis, Layer of Protections Analysis, Risk Tolerance Criteria, and Safety Instrumented System design.  Most recently, he authored “Making Sense of Risk Tolerance Criteria,” which was published in The Journal of Loss Prevention in the Process Industries and “Atmospheric Tank Failures: Mechanisms and an Unexpected Case Study,” which was published in Process Safety Progress.

Mike received his Bachelor of Science and Master of Science degrees in Chemical Engineering from the University of Missouri-Rolla and a Master of Business Administration degree from Babson College in Wellesley, Massachusetts.

Tim Herbig’s interest in safety stems from his long held desire to help others and  his realization that the field of process safety has relatively few resources for those trying to grapple with standards as a secondary or tertiary part of their job description. Tim most enjoys his work when designing safety systems and performing Safety Integrity Level Calculations. He graduated from Missouri University of Science and Technology with a Bachelor of Science in Chemical Engineering and uses the knowledge he gained in his consulting. When not making the world a safer place, Tim enjoys recording and performing music on the guitar.

Maria Vega – Westhoff has worked in Process Safety since 2015 as a Safety Consultant at Bluefield Process Safety, LLC. Her interest in safety grew while briefly working in the manufacturing industry. She was given the chance to assist a safety committee to bring safety improvements to the plant and work extensively with the plant’s contractor safety program. Process Safety Management became a passion for her after learning about the subject while completing her Bachelor of Science in Chemical Engineering at Missouri S&T.

She is an experienced PSM and RMP Compliance Auditor. In school, reliability was an interest to her and after learning about its importance to the safety of a facility she has worked to improve clients Mechanical Integrity programs and improve and organize process safety information.

Outside of work, Maria has a passion for philanthropy and is an advisor for a chapter of her college sorority.



Corey Whelehon has been working in process safety since graduating in 2013 with his Bachelor of Science in Chemical Engineering from the Missouri University of Science and Technology. Corey’s interest in the chemical and process safety field stems from his desire to protect others. Early in life, his interest was in public safety. Once in college, the passion for protecting others merged with the desire to further understand the molecular world after hearing of multiple accidents in the process industry. This enthusiasm grew after taking multiple process safety oriented class in college. The critical thinking and process knowledge required in adequately addressing and identifying hazards during a PHA and LOPA process is of personal significance to him.

While not at work Corey enjoys watching/playing sports, discovering places of interest, and spending time with those closest to him.
