Hi: I've posted
my report of this incident at http://ucih.ucdavis.edu/docs/ll_CalorimeterFailure.pdf
for your reviewing pleasure. The listserv chokes on embedded
images. This was a
very near miss and thankfully, no one was injured. If your
chemistry/chemical engineering/materials science folks use this technique (and
it's a pretty classic one), it would be good to follow up with them about
routine maintenance on the bomb vessel. Don't forget undergraduate
teaching, where it's taught in p-chem lab. Ya'll be
safe out there, Debbie ------------------------- Debbie M. Decker,

I used the Parr adiabatic bomb calorimeter during my Master's and Ph.D..
programs (45+ yrs ago) to ultimately determine the caloric value
of saltmarsh grass roots and leaves. I had to do this monthly-several
samples for each type of plant part and species. Each time I shut that lid to
burn the sample, I had the fear that the calorimeter lid would blow.
Seems I wasn't wrong to worry and very lucky that my work turned out safe.
Imagine the safeguards that these modern calorimeters have that my calorimeter
was missing.
