Flame retardants cause toxic fumes in house fires

Toxic fumes in fires are deadlier
than burns, experts say.

Now here is a rather ironic twist to a chemical that was supposed to make materials safer in case of fire: Some of the flame retardants added to common household products increase the danger of toxic gases that are main cause of death in fires.

The flame retardants that contain the chemical element bromine  were added to household products such as carpets, furniture upholstery, plastics, crib mattresses, car and airline seats and more to suppress the visible flames in fires.

Some scientists call these flame retardants “halogen-based” flame retardants because bromine is in a group of elements called halogens.

The dangers of flame retardants

But a new study highlights the dangers this group of flame retardants may actually bring to a fire.

While halogen-based flame retardants are effective in reducing the ignitability of materials, they also increase the amounts of carbon monoxide and hydrogen cyanide that are released during combustion.

Contrary to popular belief, it’s the inhalation of toxic gases and not burns that causes the most deaths and most of the serious injuries sustained in fires.

Almost 10,000 deaths from fires occur in industrialized countries around the world each year, and about 3,500 in the United States.

How do flame retardants work?

The main categories of flame retardants are brominated flame retardants, mineral-based flame retardants and intumescent agents (that swell when heated so that flames cannot penetrate the barrier).

They suppress visible flames or slow down the combustion process or form a barrier between materials.

Many common household products and children's
products contain flame retardants.

The researchers found that mineral-based flame retardants had little effect on fire toxicity, while most intumescent fire retardants actually reduced the amount of toxic gases released in a fire.

Reduce your exposure to fire retardants and other toxins

Many studies have linked flame retardants with negative health effects.

In order to reduce exposure, the Department of Health in Washington state suggests cleaning and dusting the home regularly since dust is a main source of exposure, replacing old foam products (from before 2005), buying electronics without Deca-BDEs in them and disposing of old household items properly.

Using an air purifier with activated carbon and HEPA will also help keep your indoor air cleaner and healthier by removing irritating and potentially harmful chemicals, gases, odors, particles, dust, bacteria, viruses and molds.

AllerAir offers powerful air purifiers for the home and office and also specialized air purifiers for common concerns such as allergy and asthma, tobacco smoke, MCS and chemical and odor control.

Air pollution risks: Stroke and memory loss

Bad air quality days have been linked to a higher risk
of stroke and memory loss, according to new studies.

By now, we all know that living in a metropolitan city, near a busy highway or close to industry is bad for your health.

But researchers are still figuring out just how bad it is. Previously, air pollution has been linked with problems of the respiratory and cardiovascular systems, heart and lung diseases.

Now you can add two more risks of air pollution to the list – stroke and memory loss.

Two studies in the Archives of Internal Medicine have come to these conclusions after watching Boston area residents on Good and Moderate air quality days and after monitoring women in higher-pollution areas in the US.

The women in the second study experienced a faster long-term decline in thinking and memory skills, researchers found.

This means that even levels generally considered safe by health authorities could affect people’s health negatively, experts say.

Whenever air quality is deteriorating, experts advise people with respiratory diseases to stay indoors, especially during the rush hour times.

The Boston study shows that air pollution might impede the body’s ability to regulate blood pressure (when blood vessels dilate and constrict in response to the environment to keep it constant), which in turn increases the risk of stroke for certain people.

The same reason could lead to the memory loss documented in the second study, since air pollution may affect blood flow to the brain and therefore cognitive function, researchers say.

Women should not be too concerned by these findings, they suggest, but the results may warrant further research into the effects of air pollution on thinking and memory.

Make sure you breathe clean indoor air

While experts suggest for people susceptible to outdoor air pollution to stay indoors on bad air quality days, indoor air pollution may be just as bad if not worse for people’s health.

Most indoor environments feature a variety of pollutants and aggravating agents, including airborne chemicals, gases, fumes, odors, dust, particles, bacteria, viruses and mold.

AllerAir's air purifiers for the home and office
feature activated carbon and HEPA air filters.

Apart from source control and adequate ventilation, a portable and powerful air purifier with activated carbon and HEPA air filters can make a huge difference in the air quality inside the home.

Activated carbon is the most important filter media to remove chemicals, gases, odors and vapors, while HEPA is an important filter for particles, dust and allergens.
