I saw the last launch of Antares and noticed, that they drained the LOX to the ground in case launch cansellation! Is it right? Is it safely? There were many vapors! Iwonder if there is a spacial place/pool with grit or maybe water?

There were many vapors! Iwonder if there is a spacial place/pool with grit or maybe water?Standard procedure is to drain the LOX is fuel back into tanks of ground facility in case of scrub. The vapor visible is venting of oxygen gas constantly boiling inside the tank.
And I wonder whether it is a pool with water or with grit (something else)?
