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.

I've posted my report of this incident at 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,
