Failure mechanisms of gas cylinder exposed to fire – a large-scale experimental study

Popis výsledku v původním jazyce

The failure of high-pressure gas cylinders in fire scenarios presents a serious hazard due to the potential for explosion, fragmentation, and fireball formation. This study investigates the behavior of cylinders containingflammable (hydrogen, acetylene, liquefied petroleum gas – LPG) and non-flammable (oxygen, nitrogen) gases when exposed to fire, with an emphasis on destruction mechanisms, explosion pressure, and mitigation strategies.Large-scale experiments were conducted under realistic open-air and confined conditions, with parameters such as internal pressure, surface temperature, fireball size, overpressure, and fragment dispersion recorded.Each gas type was selected to represent a distinct failure mechanism: compressed gases demonstrated rapid rupture and pressure wave propagation; LPG cylinders exhibited BLEVE behavior with violent fragmentation;and acetylene, stored in dissolved form with fragmentation and fireball creation. Even non-flammable gases contributed to overpressure and fireball formation when interacting with ambient flammable vapors. Confinedspacetests confirmed significant amplification of overpressure and structural damage compared to open environments. Controlled destruction via shooting through the cylinder shell as an intervention proved effective inpreventing uncontrolled explosions by enabling safe venting under fire conditions. These findings provide essential safety data for the development of tactical guidelines, supporting improved risk assessment, emergencyplanning, and mitigation strategies in incidents involving high-pressure gas storage and transport.
