The presence of impurities, indicating oxygen within these gases, can lead to violent combustion and substantial heat generation upon ignition, potentially causing an explosion.
Noa'tu râ i te reira, 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 Te mau mana'o tauturu no te. A gas must be combustible and capable of producing substantial heat to trigger an explosion.
