Flame retardant chemicals help keep foam and plastics from catching on fire. But certain kinds of these chemicals are building up in people. And hundreds of studies are suggesting links to problems with brain development, and thyroid and fertility problems. In the final part of our five part series… Rebecca Williams reports on the alternatives to these chemicals:

PBDEs – or polybrominated diphenyl ethers – are flame retardant chemicals. Penta-BDE is a type that was the go-to chemical for furniture for more than 30 years. Penta was phased out in 2005 because of health concerns. So companies needed alternatives. Now they often use a chemical called chlorinated tris. But there’s a problem.

“Chlorinated tris was removed from children’s sleepwear in the 70s after it was shown to cause mutations and cancer in animals.”

Arlene Blum is one of the scientists who discovered the chemical could mutate DNA. She also discovered the chemical was being absorbed into children’s bodies when they wore their pjs.

“It’s now being used as the flame retardant in furniture and baby product foam across the U.S.”

Blum is a chemist at the University of California Berkeley. She recently published a peer-reviewed study in the journal Environmental Science & Technology. She and her team found chlorinated tris in furniture. And they also found it’s migrating out of products and getting into house dust. And then there are other newer flame retardants.

“The other main substitute is called Firemaster. It’s a mixture of four chemicals, two of which are known to be toxic and two of which we don’t know too much about.”

None of the three big chemical companies wanted to be recorded. One of the companies, Albemarle, didn’t respond at all. Both Chemtura and ICL Industrial Products said in email statements that their flame retardant chemicals are extensively studied and safe.

Furniture companies say they’re in a bind. There’s a California regulation called Technical Bulletin 117. It requires the foam in upholstered furniture and baby products to meet a certain fire standard. And that usually means companies have to add flame retardants to the foam to meet the standard. Companies often don’t want to make separate products just for California, so they just treat everything with flame retardants.

Andy Counts is CEO of the American Home Furnishings Alliance. He says back when they were using penta-BDE… they were told it was safe. And they believed it was. Now, he says furniture makers are switching to new chemicals. They’re being told those are safe. And they believe they are.

“Certainly when we started using penta years ago there was no indication of any harmful effects. So it’s always a danger to use substitutes unless you have all the science in front of you. We feel confident that we have that. But as a furniture manufacturer we would like to avoid any questions about the safety of our products.”

At the same time, a handful of companies have moved away from PBDEs and other suspect flame retardants altogether.

Arlene Blum says it’s a good idea to reduce your exposure to those flame retardants. She says they migrate out of products and get into dust.

“You just want to be really good about keeping dust down in your house. Do a lot of vacuuming with a HEPA filter, wet mopping and then always washing your hands before you eat.”

She says one rule of thumb is to look for the little white label on furniture and baby products with foam in them that says it meets California TB 117… and then avoid buying that stuff if you can.

She says we will all probably be surrounded by PBDEs in our homes for decades.

The hope is this new generation of flame retardants will be safe. But there’s no government standard to guarantee that.
