This is a very dangerous demo as we all know. I would
be very uncomfortable to prepare anything that could be taken as an
endorsement of the demo. An alternate method should be recommended that
is safe. Additionally, every attempt should be made to keep teachers
from doing the demo!

When I read about this yesterday this was exactly my
reaction. It sounds like the same experiment that uses methanol and
the demonstrators are just unaware about the conditions that cause fires or
they just underestimate the risk of the fire and explosion and don't provide
proper protections for their students. I am wondering if CCS should
issue some sort of warning about this particular demonstration in high
schools - not so to stop the demonstration but rather to explain the risks
associated with this and suggestions for steps to prevent these incidents.
What do you think? Bob

Yesterday's High School Laboratory Fire in New York City

>I
was distressed to learn once again of a serious high school laboratory
accident, this one occurring yesterday at a New York City High School.
According to media reports, a flash fire occurred during a demonstration in
the high school's laboratory resulting in injuries to two 10th grade
students, one severely.

>This accident is all too similar to
the one we highlighted in a recent video safety message released by the CSB
that specifically focused on potential dangers in high school chemistry
laboratories. The CSB’s safety message entitled "After the
Rainbow," features accident survivor Calais Weber in her own words
describing how at age 15 she was burned over 40 per cent of her body during
a chemistry demonstration performed by her teacher at a prestigious boarding
school she attended in Ohio. That accident occurred on January 23, 2006.. Our
chemical investigation screening process regrettably regularly reports
similar accidents.

>Though information at this stage is very
preliminary, media reports indicate the accident that occurred yesterday in
Manhattan may have been similar to the type of demonstration that critically
injured Ms. Weber in that it attempted to show how chemicals react in
different ways giving off different colors. . The demonstration in the CSB
video showed the use of highly flammable methanol to depict how various
mineral salts produce different color flames when burned.
>
>The
CSB believes that accidents in high school laboratories occur with alarming
frequency. Yesterday’s incident is yet another example of a
preventable incident and a reminder of the need for exacting safety measures
to protect students and school property. As Calais states in the safety
message, her accident should never have occurred, and that with better
attention to good safety practices, similar accidents can also be avoided.
She says, "It feels with this type of injury that you’ve had so
much taken away from you unnecessarily and to keep reading about other
people who have had very similar experiences, it’s tragic and
shouldn't
happen."
