Hi all,

A lab here recently found a container of isopropylamine picrate dating from 1977 in a scintillation vial. Fortunately there’s only ~50 mg, but we’re a bit hesitant on how to proceed because we can’t find much information on the material, or even amine picrates in general. Our environmental programs team has reached out to some contractors on possible disposal options, but we’re trying to assess the viability of inactivating it ourselves. As an aside, I seem to remember hearing at a workshop that some explosives become more sensitive if they “survive” a previous explosion or impact, but I can’t for the life of me remember the term for this property. If anyone could help with that you’ll help preserve my sanity. Thanks!

Sincerely,

Jack Reidy (he/him)
