You might want to have your people take a closer look at that regulation. In my research, it looks like they're referring to bulk ammonia, like the kind used by the Lab and Housekeeping. It's grouped with chlorine and other noxious cleaning materials.

I found a really interesting exchange on this very subject on the Unversity of Buffalo discussion board. The URL is http://listserv.buffalo.edu/cgi-bin/wa?A1=ind0011&L=pnatalrn. This may give your a little more insight on the Ammonia ruling.

ASHES, the organization for Waste Management and Emergency Preparedness only mentions Ammonia when used as a cleaning solution.

This ruling may be a case of "one size does NOT fit all!"
