I would be
opposed to any ban of methanol, in the classroom and for any chemical
demonstrations. As pointed out,
by others, the problem is not methanol, but lack of proper training for
demonstrators. In the 1980's
and early 1990's, there were demonstration programs for teachers through ICE,
Hope College, and Dreyfus. We
taught safety along with demonstrations and proper techniques. Unfortunately, there are no national
programs that teach demonstrations at the present time and teaching proper demonstrations techniques is not part
of a college curriculum. These days,
many teachers get their demonstrations from conferences such as ChemEd, BCCE,
ICCE, and NSTA. While most
demonstrators, are responsible and observe safety, some do not. There are a lot of less responsible
demonstrators on YouTube. When
directions for these demos are distributed, they may address chemical safety,
but do not address safety in setting up and performing these
demos. While ACS
CHED, Flinn Scientific, and CCS has a list of safety guidelines, they do not
address many of the safe practices necessary for demonstrations. Only Flinn has produced some safety
videos for demonstrations. Without going
into a long dissertation, here, one of the most important practices is proper
preparation using premeasured quantities of materials in small containers
rather than pouring reagents, such as methanol, from large containers.
Should the demonstration not work, or end prematurely, the demonstrator must
insure that there is no active heat, flames or reaction, then move it out of
the way and start over with fresh materials and apparatus. Trying to prolong a demonstration is,
as we have observed from these accidents, a prescription for disaster.
In my opinion,
probably the best organization to address safety practices is Jim Kaufman's
Laboratory Safety Institute. In
addition to his regular instructors, Jim employs a number of high school
teachers and demonstrators. He
gives workshops at many schools and teacher conferences which would reach the
intended audiences. David Our job is to call
attention provide a safe alternative for this one, and state that science
teachers need more sound education in the sciences and how to do demos;
let's stay away from policy issues - banning MeOH or anything else.

Support I'm already rolling on that. I started work last
night to get a group of people together who would be the go-to folks for the
segment to comment on camera, outline the issue/history of it, etc.
Basically prepackaging all the background footwork done that someone would
need to do *exactly* that. I possibly have a media contact or two
through some other channels. Anyone who wants to help compile
the case histories etc. should contact me off list. It is quite clear that we can't solve the issue our
normal way - it is going to take some media attention so that administrators
and parents push it. A limited email I sent out last night for
initial feelers was titled "Let's get to the end of this rainbow once and
for all". It makes a great story; I can imagine the tag lines
now "invisible danger in the classroom", "your child at risk"
etc. The only question is the scope/scale. We obviously
need to address all methanol/flame demos, but do we move beyond what has
already been called for and go for an outright ban on using methanol
etc. Rob Toreki On Oct 31, 2015, at 1:04 PM, Laurence Doemeny <ldoemeny**At_Symbol_Here**COX.NET>

information about the hazard to the teachers and administrators.
Apparently some instructors don't know there is a
problem. My suggestion is for the ACS and teacher organizations
to jointly contact local and national news media to have a segment on the
dangers of some of these demonstrations and how to perform them
safely. That should get parent and school administrators
attention. This would make a nice PBS Frontline or 60 Minutes
segment. The Chemical Safety Board makes outstanding videos and
excellent reports but their reach appears limited. Laurence Doemeny From: DCHAS-L
