71) If AdBlue ® overheats for a prolonged
period inside the tank to over 50
°
C (for
example, due to direct solar irradiation),
the
AdBlue
® may decompose and
produce ammonia vapours. Ammonia
vapours have a pungent odour when the
cap of the AdBlue ® tank is unscrewed,
therefore be careful not to inhale any
ammonia vapours in the tank outlet. In this
concentration, however, the ammonia
vapours are not harmful or dangerous to
health.
