Is infrared radiation dangerous?
In general, no — at least from naturally occurring physical processes. Any form of radiation — including visible light or radio waves — could potentially be dangerous if highly concentrated into a narrow beam (that is the principle of lasers) of very high power. We are immersed in infrared radiation everyday. It is nothing more than heat. On the other hand, you certainly would not want to place your hand on a hot stove, in which case IR radiation would be dangerous.
