Petrochemical industry sites such as chemical reactors and fuel refineries are the most dangerous sites for explosion accidents. The flame propagation and gas explosion of hydrocarbon gas in a containment is influenced by the structure shape. In this study, a containment structure was tested to understand the effect of the length-to-width ratio on methane gas explosions in a fixed roof storage tank. The results show that the flame development and the pressure curve were stable, and the final averaged pressure remained at 3.8 bar until a length-to-width ratio of three was reached. At a length-to-width ratio of five, the flame front and pressure variation became unstable, the peak pressure increased, and the final pressure decreased; this means that the combustion is a fastburning and partial explosion. When the structure became longer (ratio greater than eight), the pressure increased sharply to 51.9 bar and then reduced to 3 bar at monitoring point 7 located at the end wall. The pressure behavior shows that the flame propagated over a great distance, which created the explosion condition for the unburned gas in the end area of the containment.
