It's been used by the Navy for years with their thermal run away situation with aircraft battery. I for one have used it on the aircraft situation I've encountered.
If you are worried about freezing by adding the KOH, mix in alcohol. I would think adding 28%KOH to a bubbler will not yield you any gain. My 2cents.
