Concerned about formaldehyde fumes, the Federal Emergency Management Agency has prohibited its employees from entering thousands of stored trailers. And the hurricane victims living in some 50,000 trailers in Louisiana and Mississippi? Well, FEMA hasn’t gotten around to seeing if those trailers are toxic yet — last week, the agency postponed plans to begin testing — but eh, they’ll be fine. FEMA says it’s especially concerned with uninhabited trailers sitting unventilated in the sun. Louisiana Sen. Mary Landrieu (D) is unconvinced: “I don’t really buy that argument. It makes no sense, in that most of these (occupied) trailers are closed up and locked during the day.” She adds, “This double standard is wholly unacceptable.” But not unexpected.
