The presence of impurities, indicating oxygen within these gases, can lead to violent combustion and substantial heat generation upon ignition, potentially causing an explosion.
Nevertheless, even gases such as hydrogen and methane are unlikely to explode if impure. The risk of explosion depends on the specific oxygen to hydrogen ratio, which must hit a critical threshold to pose a hazard.
It’s crucial to note that not all gases are explosive. A gas must be combustible and capable of producing substantial heat to trigger an explosion.
