(Olympia, WA)  --  Washington State Attorney General Bob Ferguson wants to improve safety conditions for workers at the former plutonium production facility at Hanford.  Ferguson has filed an emergency motion to force improvements in worker-safety conditions at the site.  The motion requests that a federal judge intervene in site operations to protect workers from being exposed to toxic chemical vapors.  Ferguson tells KING-5 that there's a "culture of indifference" by the federal government and its contractors, and says he'd like to see the judge take immediate action.
