The .pdf states the bomb was charged to "5 psi". My old 1950 bomb is charged to 25 atm. Is there a mistake or has the procedure changed?

Hi:
I've posted my report of this incident athttp://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
