Has anyone ever dealt with dismantling dioramas, which may
          have been on exhibit for decades, and where specimens or
          artifacts may have been treated with toxic substances, such
          as arsenic or various fumagants.  How was it handled?  Any
          recommendations?  I am not involved in dismantling an
          exhibit, but am using this information for my thesis titled
          "Open Exhibits: A Conservation Challenge to Museums."

          Please respond to [log in to unmask]  Thank you for any
          information you may have.
