FEMA formaldehyde fubar.

The Associated Press: FEMA seeks immunity from suits over trailer fumes

"It is well-established that the (government) is only liable in such situations if it supervised and directed day-to-day activities of its contractors, which did not occur in this case," they argued in the court papers.

The government's lawyers also wrote that a review of legislative history left "no doubt" that Congress intended to enact a broad bar against any such claims arising from disaster relief actions.

Tony Buzbee, one of the lead lawyers for the plaintiffs, said FEMA and the trailer manufacturers "worked hand in hand" after the 2005 hurricanes and should share legal liability in the cases. The lawsuits contend FEMA ignored concerns about formaldehyde levels in trailers for months after Katrina.
