Just to muddy the waters a bit -- in some cities, San Francisco for
instance, some apartment blocks had ammonia-cycle cold boxes in each
apartment. These were supplied by an ammonia compressor in the
basement. ISTR that maybe once a year, the SF fire department finds a
leak. Even though the system might have been turned off years ago,
there's stll gas in the pipes. A friend lived in one of these place
for a while.

Unfortunately, I can't find a good cite for this.
