Why is it difficult to detect a hydrogen fire? This is because hydrogen flames emit very little of the infrared (IR) radiation that causes humans to sense heat when standing next to a flame. With nothing to see and little radiant heat emitted to the environment, human senses won’t warn people to stop as they approach a hydrogen flame.
Why is hydrogen fire invisible? Hydrogen burns with a pale blue flame that is almost invisible during daylight hours, so fires are almost impossible to see with the naked eye. Hydrogen fires have low radiant heat, so you can’t sense the presence of a flame until you are very close to it (or even in it).
