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.
