1. The hazards imagined for land debris are things like nitrogen tetraoxide and
other potentially toxic propellants.

2. Toxicity is about concentration.  Drink a cup of ammonia, and you are likely
to have a bad (but possibly short) day.  Dump a cup of ammonia in a swimming
pool, and you'll be quite safe jumping in.  (Heck, if you are in a public pool,
a few cups of ammonia have most likely already been dumped in).
