Summary
This case study examines the December 2004 explosion and fire at Marcus Oil’s Houston wax-processing facility. It analyses defective pressure-vessel alteration welds and oxygen contamination of the nitrogen system, alongside physical testing and regulatory gaps. Recommendations address vessel repair standards, overpressure protection and personnel training in inerting-system operation.
