The formaldehyde fuss
Tuesday, September 25th, 2007When it comes to the formaldehyde issue, it’s hard to know what’s right, what’s wrong, what’s hype and what’s fact. On Monday, the RV Industry Association took the proactive step of bringing the issue to the forefront of industry discussion during its annual membership meeting in Las Vegas.
The association brought in a hired gun to bring manufacturers, dealers and suppliers up to speed about the issue which has garnered media attention to the point some consumers wonder whether they’ll be poisoned in their RVs, as some media outlets have contended. The bottom line is that the media hype is groundless and it is up to us to educate consumers about the formaldehyde fuss.
For the most part, the formaldehyde issue is yet the latest hit job by what Rush Limbaugh calls the drive-by media – reporters acting like gang members who spray bullets into a crowd causing mass panic and hysteria only to calmly drive away unscathed and unnoticed as the gangsters look for their next victims.
Dr. Lee Shull is a professional toxicologist who works as the corporate risk services director for Environmental Resources Management in Sacramento, Calif. He was invited by RVIA to expose the fallacy of the formaldehyde issue. Monday morning, he did an excellent job putting the issue in its proper context. Here are a few bullet points you can use to reassure customers that RVs remain safe.
- Formaldehyde is one of the most naturally occurring organic compounds in the universe
- It is not unusual for people to be exposed to formaldehyde daily through clothing, carpeting, building materials and even food
- It is often used as a disinfectant and antimicrobial solution
- It is fed to livestock
- It is found in soap and cosmetics
- It is used in the food industry to process fish, cheese and juice
- It has been used for 70 years to create exceptionally strong glue that securely bonds one material to another
When wood products are manufactured using glue, virtually all the formaldehyde is consumed in the process. In fact 99 percent of the compound used is chemically bonded into the materials. Less than 1 percent is considered “free formaldehyde” which is released over time as a gas. The news media, on the other hand, frequently suggests that 100 percent of the formaldehyde used in the manufacturing process is available as an “off gas” which is harmful to humans, Dr. Shull said.
Air samples were taken daily on 96 FEMA trailers over a 14-day period. Two groups of trailers were sampled. Group A turned on air conditioners and left the bathroom vent open. Group B shut off the air conditioner, opened the windows and left the vents open. The goal was to see whether the concentration of formaldehyde could be altered below 0.3 parts per million (ppm), the point at which exposure may result in discomfort and irritation.
Group A, the users who shut the windows and recirculated air through the air conditioner, experienced irritating levels of formaldehyde gas 12 of the 14 days. But, Group B, which opened the windows as recommended, recorded less than 0.3 ppm after the fourth day. What a surprise.
Dr. Shull said there were other factors in the Gulf Region contributing to higher formaldehyde levels — factors the drive-by media chose to ignore, including:
- The trailers were recently constructed and it takes time for the 1 percent of free formaldehyde to escape from wood products in order to be off gassed
- The trailers were shut tight due to hot humid weather
- Formaldehyde was also released from nearby rotting wood associated with downed trees and broken homes
- People were also smoking indoors and tobacco products release their own formaldehyde
- Gas cookers were often involved and they, too, produce formaldehyde
- People were also exposed to cleaning agents and personal care products, like cosmetics, which release formaldehyde
Dr. Shull noted the Occupational Safety and Health Administration, Department of Housing and Urban Development, Environmental Protection Agency, the Agency for Toxic Substances and Disease Registry, Consumer Product Safety Commission and World Health Organization all have different standards as to what is and is not an acceptable level of formaldehyde concentration. As expected, the media picks the lowest level of “acceptable” concentration adopted by one of the agencies and portrays that number as undisputed fact.
A total of 28 different epidemiology studies of factors contributing to illness have failed to show a correlation between formaldehyde and any evidence of nasal cancer. Yet the media is all hyped up about the issue because studies have shown that high levels of formaldehyde did cause cancer in laboratory rats. What the media didn’t mention are these inconvenient facts about the study in which rats were exposed to various levels of concentration for six hours a day, five days a week over two years:
- Of the 159 rats exposed at a concentration of 2 ppm, none of the rats contracted cancer
- Of the 153 rats exposed to a concentration of 5.6 ppm, only two rats contracted cancer
- Of the 140 rats exposed to a concentration of 14.3 ppm, 94 of the rodents developed cancer
Remember, the level of human exposure in the tested FEMA trailers was 0.3 ppm — enough to cause irritation, but nothing else, even among sensitive individuals. It was nowhere near the concentration to which the lab rats were exposed. The heart of the controversy, according to Dr. Shull, is that science has clearly demonstrated there is a point at which a dose of formaldehyde causes no observable problems. But government agencies can’t let facts stand in the way of a good regulation.
You see, because a rat exposed to high levels of formaldehyde can contract cancer, the government assumes there is a one in a million chance that a human could get cancer from the same substance — even at levels 1,800 percent lower than that known to cause cancer. And that assumption forms the basis for regulatory intervention and growing the size of government to protect us all. Whenever we see the government concerned about that special one-in-a-million person, you can bet that scores of attorneys will find thousands of potential victims in our country of 301 million people, of which 8 million use RVs. Just follow the money.
