Re Lew Malchick's post about chemical safety in schools and finding picric
acid in a school in 1985:

When working in NYC schools back in the 1970's, I recall discovering a
number of bottles of picric acid in the chemical storage room at Francis
Lewis High School in Queens, NY (it was in either 1976 or 1977). I was
aware of the hazards associated with picric acid, and I quickly decided to
take action. I don't recall any mention of it on the evening news; but
when I called in my discovery to the local firehouse, I was advised to
evacuate the school immediately, and that they were sending fire trucks
and the bomb squad to deal with this. In this incident, there were no
injuries and no property damage. But it certainly doesn't surprise me that
about eight years later, the incident described by Lew Malchick occurred,
also in a NYC school. Obviously, there was no effective mechanism in place
in the 1970's to spread this information around, in order to prevent
recurrence of the same problem (along with possible explosion, fire, and
potential serious injury).

Today, however, information spreads almost instantaneously, about all
kinds of really important things, such as hacked cloud storage accounts
that reveal nude photos of celebrities.

When the well-known and fairly ubiquitous "Rainbow" experiment went awry
in another NYC school last January, resulting in serious injury to several
students, after so many similar incidents had been reported involving use
of methanol and an open flame without proper safeguards, I am certain it
occurred to many of us that there is no longer any excuse for professional
educators to put students at risk when the associated hazards have already
been well publicized (and when much safer procedures are available to
accomplish the same educational objectives). The CSB had, in fact, just
released an online video showing in great detail a thorough analysis of an
almost identical classroom accident that had taken place several years

I applaud the UFT (of which I am a member) and Lew Malchick's committee
for its efforts to help bring increased safety to the science classrooms
and laboratories of the NYC schools. I hope all of us in this forum
continue to spread the word and try to impart some of our individual and
collective wisdom to our local school districts, and possibly prevent
future accidents that can seriously injure our children.
