The Pascagoula gas plant experienced a fire and explosion in June 2016 caused by the failure of a brazed aluminum heat exchanger (BAHX) due to thermal fatigue. Previous process hazard analyses in 1997 and 2009 had identified BAHXs as a risk and recommended procedures to minimize damage or replacing them. However, later analyses in 2013 and 2015 downplayed the risks, focusing only on the financial costs of repairs based on the plant's experience with leaks rather than safety hazards. The 2016 incident resulted in a community evacuation and over $10 million in expenses, highlighting the normalization of risk that had occurred over time.
