Lumber Liquidators Formaldehyde Testing
Lumber Liquidators Formaldehyde Testing
Recent investigative journalism exposed a Lumber Liquidators formaldehyde content issue and revealed an unfortunate tale that may affect hundreds of thousands of homes across the US. During active federal investigations for suspicion of using illegally harvested lumber from Russia, it turns out one of the largest flooring distributors in the US may have also shipped high formaldehyde content composite wood products into California. Whether they did this knowingly to save on production costs is heretofore unknown, but this recent 60 Minutes news story sent Lumber Liquidators stock plummeting.
Has Lumber Liquidators been cheating the system by buying illegal wood and mislabeling their products “CARB II compliant” so they can sell in California?
California Formaldehyde Emission Levels
Environmental regulations often start in Europe, then show up in California, and ultimately are adopted across the US. That is exactly what happened with allowable formaldehyde emissions from composite wood products. Composite wood includes plywood, OSB, MDF, and much of the lower-cost “hardwood” flooring options in the US and are subject to more stringent formaldehyde emission regulations when sold in California. But even Californians weren’t safe from the Lumber Liquidators laminate flooring made in China.
The California Air Resource Board (CARB) sets the most stringent formaldehyde emission standards in the US. It has based their allowable emissions on clear health data indicating formaldehyde can be a real problem for human health. Many projects build with materials full of toxins, then lock occupants up in air-tight buildings without adequate mechanical ventilation, and then we’re surprised when American’s have higher rates of asthma and other respiratory irritations.
The 60 minutes expose shows formaldehyde test results from products purchased around the country. Formaldehyde testing of Lumber Liquidators products was performed by 3rd party laboratories. Red arrows show allowable CARB limits. Note that most of the Lumber Liquidators laminate flooring tested above the CA allowable limit (lower red line). Also note how many samples were over 1000 times higher than what is allowed into CA.
CARB is fighting the good fight, and soon the US will have similarly strict limits for formaldehyde emissions. But if Lumber Liquidators can get away with this I wonder if enough oversight and enforcement is in place to truly protect our population from unnecessary indoor air pollution such as formaldehyde.
Lumber Liquidators Chinese Laminate Mislabeled?
This part of the story was most troubling. Apparently the Chinese manufacturers of Lumber Liquidators product were knowingly saving the client money AND applying “CARB Compliant” labeling on these products. This will inevitably become a case of “who knew what when”.
How to find out if my flooring has high formaldehyde content?
There are basically two types of environmental testing services relevant to this story:
- Chamber Testing of Bulk Materials. There are many testing methods available for chamber tests, but California has their own standard methods which manufacturer’s must comply with before they can apply the “CARB-Compliant”stamp. These tests range from $700-2500 per sample. We’ll post another blog illustrating interesting results from recent tests we ran on building materials.
- Ambient Air Quality Testing. Here, too, there are many different options and standards for testing. It takes a good environmental inspector or industrial hygienist to know what test is most appropriate. It also takes an expert to interpret these results and put them in the context of each particular case.
Class Action Suit on the Way
So the class action law suit is on the way. In the meantime we’re doing various formaldehyde chamber tests for VOCs and formaldehyde on bulk materials, and we continue to offer ambient air testing for homes, offices, medical and institutional buildings. Whether you’ve got Lumber Liquidators product in your building or not, let us know if you’d like your air or building materials tested for formaldehyde. If you suspect your building has contaminated Lumber Liquidators flooring it is prudent to do testing and possibly time to join the class action suit.
