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?

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,
