Safety has to be the number one concern when dealing with suspect containers. 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? Larry == From: "Debbie M. Decker" Date: March 31, 2009 2:00:57 PM EDT (CA) Subject: RE: Picric acid 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. Debbie ------------------- Debbie M.
