Remembering the human toll of Texas City and Deepwater Horizon and applying those lessons learned can prevent similar tragedies. In this episode, Trish and Traci discuss two major BP incidents: the 2005 Texas City Refinery explosion that killed 15 workers when an overfilled tower created a geyser of hot raffinate that ignited, and the 2010 Deepwater Horizon explosion that killed 11 workers and caused the largest U.S. marine oil spill when cement failed to properly seal a well. Key factors included faulty equipment, misleading indicators, inappropriate safety messaging and failure to learn from near-misses. These tragedies led to industry-wide improvements, including standardized process safety metrics, occupied building risk assessments, and better hazard management.
