10 Shocking Facts about Flame Retardants
The Dangers of Flame Retardants
Flame retardants – globally recognized as toxic contaminants – have been associated with reproductive disorders, cancer, immune dysfunction, hormone disruption, suppressed thyroid function, and serious damage to fetal and child brain development. Here are 10 facts you need to know to protect you and your loved ones from these dangerous, pervasive toxins.
1.Your Dust Bunnies Are Toxic
According to Duke University associate professor of environmental chemistry Heather Stapleton, "If you really look at what's in your dust, particularly for some chemicals, it's just as concentrated – or more – as what you'd find in sewage sludge."What she and many other researchers discovered is flame retardants like PBDEs and chlorinated tris escape from the foam and accumulate in dust. Dust bunnies, by their nature, collect greater amounts of these chemicals. The more that around, the greater your exposure. Pets and little ones crawling on the floor may be most susceptible.
2.The 2006 Ban on PBDEs Did Not Make Furniture Safe
Although PBDEs were supposedly banned in 2006, the chemical used to replace them is equally as dangerous. Chemical manufacturers reverted to using chlorinated tris (or TDCPP), a chemical banned from use in children's pajamas in 1977 because it causes DNA mutations and cancer. Even the newer chemical known as V6 contains tris. Research shows chlorinated tris is more toxic than the pesticide chlorpyrifos, a known neurotoxin.
3.Baby Products Are Loaded with Flame Retardants
You know why you've never heard of a "foam tree"? It's because foam, despite being soft, is not natural, it's the product of mixing chemicals together. Subsequently, it comes as no surprise that car seats, changing pads, and other foam baby products are loaded with chemicals, including flame retardants. Tris and a new chemical known as V6 (which contains tris) make up about 4.6% of the mass of the foam in baby products. All the same health dangers apply which is why the best way to protect your little ones is to use and expose them to as few foam products as possible.
4.Children Are Most Vulnerable
Tests have shown that children typically have three times as much fire retardants in their blood as their mothers. The reason for this is believed to be the fact that children play on the floor where dust and carpeting collect fire retardants as the previously mentioned dust bunnies. This may explain the ever-increasing number of children suffering from hormonal and metabolic imbalances.
5.Flame Retardants Affect Unborn Babies
Pregnant women need to be especially aware of exposure to flame retardants. Research has shown that PBDEs have no concerns crossing the placenta and can transfer harmful effects from mother to fetus. PBDEs have been found in the fetal blood of women exposed to products that have been treated with flame retardants. Observations of children with higher levels of PBDEs in their blood revealed greater incidences of hyperactivity and decreased learning and memory.
6.Flame Retardants Cause Male Infertility
Regular exposure to organophosphate flame retardants alter a man's hormone levels, leading to poor semen quality and decreased sperm count.
7.Flame Retardants Are Concentrated On Airplanes
Airplane seats may, at times, seem rock hard but they're loaded with foam. The foam used, not just in the seats, but everywhere in the airplane contains high levels of fire retardants and 100% of dust samples collected from airplanes contained most flame retardants, including TDCPP, or tris. Concentrations of another flame retardant, BDE 209, have been found to be several times higher in airplanes than in residential or office settings.
8.Californians Have the Highest PBDE Levels in the USA!
Californians have the highest levels of PBDEs, tris, V6, and other flame retardants in their blood. Studies comparing PBDE levels in residents of California to those throughout the rest of the US found Californians had twice as much circulating in their blood. [8] Another study noted children living in California have significantly higher levels of PBDEs than other children living in Mexico.
9.Chemical Manufacturers Don't Care About Your Health
Despite the science showing the extreme danger posed to human health by flame retardants, chemical companies continue to lobby politicians to keep these chemicals in our furniture. And, if persuasion doesn't work, they'll sue to keep you inhaling this stuff.
10.Blood Levels of Flame Retardants Continue to Increase
Despite chemical bans and efforts to reduce exposure to these toxic chemicals, their presence continues to rise. Flame retardants are known to disrupt hormone activity in children, especially girls who may experience reproductive health concerns and severe hormonal imbalances. We may never know the full impact of these chemicals, but we do know for certain we need to at least reduce our exposure.
9 Steps You Can Take to Protect Yourself and Your Family
It's obvious we need to protect ourselves from the damaging effects of these toxic chemicals. Here are a few steps you can take to reduce your exposure and, hopefully, limit the damage:
- Don't buy furniture that carries a TB 117 label.
- Vacuum carpets and furniture using a vacuum with a HEPA filter.
- Damp dust furniture and floors regularly.
- Don't eat on, around, or near your coach. Also, use wooden chairs without padding in your dining areas.
- Wash your hands frequently, especially after cleaning.
- Buy naturally flame-resistant materials such as wool and cotton.
- Ask your sales rep or the manufacturer about the presence of flame retardants in their products before you buy.
- Regularly vacuum your car's interior.
- Let your all service and salesmen know you don't want flame retardants in your furniture, clothes, or any product entering your home.
One Must Consider Several Factors When Selecting A Flame Retardant
Flame retardants are chemical compounds added to plastics in order to prevent, delay, or slow down combustion, reduce smoke formation, and/or prevent the material from melt collapse (anti dripping). These additives are common in numerous everyday products to avoid the ignition and burning of plastics.
The most common flame retardants are halogenated compounds, which include brominated and chlorinated types. Halogenated flame retardants are highly effective at relatively low load levels. Non-halogen, or halogen free, flame retardants are increasing in demand and include intumescents (phosphorus-based) and metallic oxides. Non-halogen flame retardants require a higher load level, and often need additional adjustments to maintain the mechanical properties of the plastic.
One must consider several factors when selecting a flame retardant. Getting to the desired performance often requires a tailored solution with several trials.
What are the test requirements this part needs to pass (burn time, extinguish time, flame spread, smoke development, industry and government regulations, mechanical properties).
What polymers and additives are used in the part.The design, shape, and surface area of the part also play a critical role in combustion.
Flame retardant additives can be compounded with the base polymer or added during the plastic processing step. Sometimes combustion may be prevented by simply adding the flame retardant to a surface layer finish on the final product.
When plastic burns, long-chain molecules of the polymer chain are degraded into smaller hydrocarbon molecules and flammable gases, such as free radicals – a process called pyrolysis. For a fire to begin, fuel, oxygen, and an ignition source must be present. Flame retardants work by interfering or eliminating one of these key ingredients, either physically or chemically. There are a few common methods that flame retardants employ to inhibit combustion and below is a description of each.
Gaseous Inhibition: halogenated compounds such as bromines and chlorines are compatible with many base polymers and are the most common flame retardant additives. During pyrolysis, hydrogen and hydroxide free radicals are produced. During a fire, halogenated flame retardants thermally degrade, releasing hydrogen chloride and hydrogen bromide that react with the free radicals in the flame. These newly formed free radicals include the halogens and are less reactive than the original hydrogen and hydroxide free radicals, thus, suppressing the volume of reactive gases available for combustion reactions. Also, this process slows combustion which in turn cools the system, further reducing combustion.
Solid Char-Formation: This form of flame retardants is often comprised of non-halogen compounds using phosphorous and nitrogen chemistries. During a fire, these types of flame retardants react to form a thick, solid layer of carbon char on the surface of the plastic. This solid layer insulates and shields the plastic, creating a barrier that interrupts the combustion process by hindering the release of more reactive gases.
Endothermic Cooling: This class of non-halogen flame retardant includes metallic oxides/ hydrated minerals, such as aluminum and magnesium hydroxides. During a fire, these flame retardants use an endothermic reaction to remove heat and release water molecules. The plastic is cooled and limits the amount of reactive gases being formed, thus hindering the combustion process. The use of hydrated compounds as flame retardants is often limited by the low decomposition temperatures of these materials since plastics processing and manufacturing often occurs at high temperatures.
There are many factors to consider when selecting the right flame retardant for a given application including the base polymer being utilized, the specific government and industry regulations and standards that must be met, as well as the desired properties of the polymer such as viscosity and density. Selecting a flame retardant can be a tricky task, which is why it is important to choose a partner, like Amcor, that has extensive expertise in various flame retardants as well as experience with state-of-the-art compounding and blending processes. Amcor will guide you through the selection process to ensure the right additives are chosen for your specific application.
What Are Flame Retardants Usually Made From
Flame retardants can be made with a whole variety of different chemicals. Some flame retardants, such as our fire retardant sprays, are water-based, free of Polybrominated Diphenyl Esters and designed using non-toxic ingredients. However many fire retardants aren't so environmentally friendly.
Commonly used fire retardants include brominated flame retardants, OFRs, TBBPA, HBCD and OPFRs. These products often contain dangerous chemicals, which are toxic to humans, wildlife and plants.
Brominated flame retardants are seen as particularly hazardous. The chemicals used in them are very similar to those that have long been banned by the Environmental Protection Agency.
Chemicals found in brominated flame retardants present a serious risk, as over time they can become increasingly concentrated inside the body. Prolonged exposure to such chemicals can therefore cause serious health problems. Fire retardants like these are particularly dangerous for children and vulnerable adults.
