Hi all,

Many of us are both authors and users of MSDSs and have long had to
struggle with these issues.   This MSDS issue has triggered a wealth of
valuable responses on the list.  Is there any interest in trying to
capture some of these ideas in a symposium at one of the upcoming ACS
meetings?  It is not too late for the San Diego meeting (although
deadlines are rapidly approaching), but Washington, DC (august 28 -
September 1, 2005) or Atlanta, (March 26-30, 2006) are coming soon.

I will organize the session if there is interest, what I need is a
consensus on which meeting as well as interested presenters.

Let me know (off the list) and we will see if we can move this forward -

I guess I'd better get into this and try to be helpful.

there are ways to determine whether or not an MSDS is probably either
defective or reliable: Look for internal contradictions and for
meaningless statements.  As one example, "non-volatile" assertion in one
place and a statement elsewhere that the vapor pressure at ordinary
temperatures is, say, "100 mm."  As another,  "Use with impervious
gloves." with no further clarification.

Several other examples of internal contradictions and meaningless
statements can be found in Chapter 2 of my book, Improving Safety in the
Chemical Laboratory; A Practical Guide, Wiley Interscience, 2nd edition,
1991.  (Excuse the plug.)

Or for the hazards of a chemical in plain English, see the "CLIPs"
published each month in the Journal of Chemical Education
