GOP backs trailer makers

But Democrats say their staff interviewed employees from one of the manufacturers, Gulf Stream Coach, who said they, too, were suffering effects from formaldehyde exposure, including nose bleeds, shortness of breath, dizziness, and bleeding ears.

Gulf Stream Coach Inc., received the bulk of the FEMA trailer contracts after Katrina, collecting more than $500 million.

Henry A. Waxman, Democrat of California and committee chairman, said the Democrats' investigation found that Gulf Stream tested the trailers, but treated the results as a public relations liability instead of a health hazard.

"It found pervasive formaldehyde contamination in its trailers, and it didn't tell anyone," Waxman said yesterday.

Jim Shea, chairman of Gulf Stream, said there was no actual testing of trailers. Instead, there was informal screening with a Formaldemeter, which is not a scientific test.

Shea said, however, that his company asked FEMA in 2006 whether it should test the trailers, but FEMA said no.

Last year, scientists tested hundreds of FEMA trailers and found potentially dangerous levels of formaldehyde.

There is no government standard for the amount of formaldehyde in travel trailers. Standards are set for indoor air quality for materials used to build mobile homes, but not travel trailers. Katrina victims now occupy 15,000 travel trailers in the Gulf Coast, down from the more than 143,000 trailers that once housed victims.
