Treatment by the generator of characteristic waste (D003) to remove  
the characteristic is permissible under the land Disposal Restriction  
(40 CFR 268).

I agree.

Safety has to be the number one concern when dealing with suspect  

Hire a consultant who has experience and who is equipped to do this  
sort of thing.  It will set you back a few bills but everyone will  
remain intact.  We had to do this at LBNL.

Here is  food for thought - I understand that this is a forum for the  
open exchange of ideas, and I don't want to discourage that.  I've  
used this list several times and I appreciate the input I've gotten  
from you folks.  But what if someone were to use this technique (or  
follow some other piece of advice) from this list server and get hurt?

Paul, et al:

In my rocket scientist days, I worked with 25 pound lots of dry picric  
acid in the lab, working to make it MORE sensitive because it didn't  
quite have the "oomph" we needed.  I'm way more excited about old  
moldy ether than I am about picric acid.

For your old picric acid, I would put it in a bucket or tub of water  
and let it soak for awhile (couple of days, perhaps).  After some  
suitable length of time, I would gently open the cap, under water, and  
allow the picric acid to dissolve in water.  It's somewhat soluble and  
once it's in solution you can ship it as a flammable liquid.  Many  
waste haulers won't take picric acid but they will take it if it's  
dissolved.  For the amounts you describe below, I don't think a bomb  
squad response is necessary.

Let us know how you decide to manage it.

Hi Ralph,

I thought that this article on picric acid was comprehensive.

Out of curiosity, what would be the best base with which to neutralize
