Ammonia is an extremely toxic gas.

Yep, lets ban it.

The ammonia products sold in stores are very diluted. Years ago I worked at a warehouse with huge freezer space that used ammonia as a coolant. It was an old warehouse and there were occasional minor coolant leaks. We were told that if there ever was a large leak to run for your life because otherwise you would be killed immediately.
