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.

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.

Flame retardant chemicals are added to hundreds of products in our homes and offices to slow the spread of fire. But during a fire, the fumes can cause problems for firefighters. In the fourth part of our five part series, Rebecca Williams reports… some firefighters say flame retardants can make their jobs more dangerous:

Flame retardant chemicals are added to hundreds of products in our homes and offices to slow the spread of fire. But during a fire, the fumes can cause problems for firefighters. In the fourth part of our five part series, Rebecca Williams reports… some firefighters say flame retardants can make their jobs more dangerous:

We started using flame retardant chemicals called PBDEs back in the 1970s. Ever since, some people say firefighting has gotten more complicated.

Kathleen Chamberlain is the Fire Marshall for the city of Ann Arbor, Michigan.

“In certain ways, I’m sure the flame retardant chemicals have made things easier: they’ve delayed fires, they’ve slowed them down.”

That’s the upside. But she says there’s also a downside.

“They’ve added a toxicity level which has made things much more dangerous for everybody.”

(fire station radio: “Battalion 1-3… “ and truck noise)

Downstairs at the fire house… Captain Tim Flack has to be ready to jump into his equipment at a moment’s notice. These days, on the way to the fire, he straps on air tanks and gets ready to put on his mask.

“You had the tough man mentality back in the old days where they didn’t wear the air packs and stuff like that. It’s to your benefit to wear your air packs and breathe the good air and not be the tough guy.”

He says all firefighters wear their air packs these days. It’s required. Turns out it’s also a really good idea.

Many firefighters are concerned about flame retardants called PBDEs. Even though two kinds of PBDEs were phased out by manufacturers several years ago, their products are still in our homes. The International Association of Firefighters says when PBDEs burn they release dense fumes and black smoke. And a highly corrosive gas called hydrogen bromide.

You wouldn’t want to breathe it.

So, firefighters are in a tricky place. Many say flame retardant chemicals are a good idea. But they want to move away from brominated flame retardants such as PBDEs. They say there are alternatives.

It’s complicated by a California regulation. Technical Bulletin 117 requires the foam in upholstered furniture and baby products to meet a certain combustion standard. And that often means companies have to add flame retardants to the foam to meet the standard.

The chemical industry stands by the safety of its flame retardants. The American Chemistry Council did not want to be recorded for this story. But in an email statement, the Council said quote: Flame retardants have been credited with saving many lives including the passengers and crew of the 2005 Air France crash in Toronto.

Many people say there are situations, such as airplane fires, where flame retardant chemicals can buy precious seconds to help people escape.

But many firefighters say in our homes, it would be smarter to deal with the sources of ignition.

Cigarettes and other smoking materials are the leading cause of fire-related deaths in the U.S. But for years, the tobacco industry fought laws requiring self-extinguishing cigarettes.

A 2008 Washington Post investigation revealed the tobacco industry and the flame retardant industry have a lobbyist in common. That lobbyist, Peter Sparber, first helped the tobacco industry fight against self-extinguishing cigarettes. Then he lobbied for tighter regulations that would require the use of flame retardant chemicals in furniture.

So first, he lobbied to protect the cause of many fires. Then he lobbied to use chemicals to retard those fires.

These days, most states now have laws requiring cigarettes to be self extinguishing.

Firefighters’ groups are joining forces to stop the use of PBDEs and other brominated flame retardants altogether. But one of the major chemical companies, ICL Industrial Products, says brominated flame retardants are the most efficient at putting out fires… and they will continue to play a vital role in product designs and public safety.
