Being around strong sources of IR such as glowing hot metals can be damaging, sure - but I do trust the data sheets for the IR leds, and I also believe that they emit nowhere near the amount needed for damage to occur. Common video cameras have IR leds to give 'night vision', there are no health warnings on them, and they put out a $%&*( load more IR than the three low powered LEDs that I used!
