Nolan Gajeski

Mr. Gajeski is a member of BakerRisk’s Process Safety Group. His work focuses on Facility Siting Studies (FSS) and Quantitative Risk Assessments (QRA) for refineries and petrochemical facilities where he has gained experience in consequence modeling of blast, toxic releases, and flammable vapor cloud explosions using BakerRisk’s dispersion and blast modeling software tool, Safesite3G©. Mr. Gajeski also has experience performing loss prevention surveys. These surveys focused on identifying and evaluating the property and production loss potential for the site. These surveys also examined a facility’s management programs (operations, maintenance, inspection, etc.) and its capabilities to minimize or prevent loss. Since leading the testing program for the Process Safety Group starting in 2020, Mr. Gajeski has led numerous testing programs including jet fire hazards to various types of building structures, thermal impacts to flexible piping, leak detection of various hydrocarbons and hydrogen, collecting dispersion and jet fire data used to evaluate the model used in BakerRisk’s dispersion and blast modeling software tool, Safesite3G©, and dozens of other test programs.
