John Kiernan is right on.  Its maddening, isn't it, to have to comply with
so much of the regulatory nonsense that we are plagued with, and have it be
so useless as an MSDS that doesn't warn of the real dangers.  Who dreams
this wasteful stuff up? Are these OSHA and JCAHO standards and statutes
reviewed periodically as they mandate we review ourselves?
