Paul-
To lend credence to Russ=92 statement, I, too, did a fair share
stabilizing dried picric acid containers. Even one with a metal
cap- soak for several hours until you see the yellowish color. Our
institution also developed mechanical means, including a pneumatically-
driven device which could remotely twist the cap off, and a non-
sparking tool which could puncture the top, allowing hydrating the
contents. But usually a gentle twist of the wrist did the trick.
I am not suggesting you try something you are uncomfortable
performing. In most cases I had a HAZMAT team notified, but not
present, just in case.
