Chairman Waxman requested documents from the Agency for Toxic Substances and Disease Registry (ATSDR) regarding the “health consultation” it provided to FEMA on formaldehyde levels in tested trailers. The ATSDR consultation ignored established safety recommendations for formaldehyde exposure and downplayed the health risks posed by the formaldehyde levels in the tested trailers. ATSDR recently changed course by acknowledging that the tested FEMA trailers had formaldehyde levels that can adversely affect human health.
