About ToxicTrailers.com

ToxicTrailers.com was launched after Hurricane Katrina in 2005 when the government spent more than $2 billion on FEMA trailers with high levels of formaldehyde that sickened thousands of people. The FEMA trailer tragedy exposed what is a widespread problem in RVs, mobile homes, modular buildings and even conventional buildings that use pressed wood products. Unfortunately, as we approach the tenth anniversary of Katrina, formaldehyde regulations are not being enforced in the U.S., and people's health is at risk. If you are having burning eyes, congestion, sore throat, coughing, breathing difficulties, frequent sinus infections or rashes, and difficulties concentrating, you may have a formaldehyde problem.

why is formaldehyde worse when heaters turned on?

We have received a number of reports that the problems with formaldehyde outgassing in trailers gets worse when the heat is turned on. Does anyone know why this would be the case?


Hi Becky:

My thoughts on why formaldehyde is worse during heating and cooling seasons.

First, formaldehyde is quite volatile and becomes more volatile at higher temperatures. It makes sense that as the insulation around the heated duct works and underneath the trailer is heated the formaldehyde is liberated and most likely just comes up through the floors.

In both the heating and cooling seasons, the windows would be closed all the time, hence very little ventilation. During other times of temperate weather, I would imagine that the windows are opened which allows the air in the trailer to turnover. Maybe, even during heating season, that it would be beneficial to open the windows for a short period each day just to bring in some fresh air and reduce formaldehyde levels that way. It may cost a few dollars per month more on heating but eliminating one visit to the doctor will pay for a lot of gas.
