Good evening everyone,

The frame of my house is partly made with old telephone poles certainly coated with creosote (tar species) and that we can still feel despite their age ... do quelqun can tell me if this is dangerous for your health?
thank you in advance

I confirm, c is mega carcinogenic.
T have any interest has a max ventilate your attic.
The posts held longer than you, t is children and following.
If the creosote was recalling walking c is not without reasons.
C was planned for the exterior wood, but especially not for inside.
Until you change the frame can cover the timber with oil to
Flax additioner of scicatif. 5 or 2% max if I remember well.
Must See on embalage, c is indicated.
Without scicatif the oil will not cure, because in principle between the sun n not
too ds your attic. it is the UV that cause this polymerisation
(C I think is the right term)
The oil covering the wood treated with creosote, the latter will prevent it from
poluer the media.
C is the technique that I've used to treat my barriers, are just that
as they are outside al must put a layer each year.

Passing the problem is the same with the railway galls.
C is not a good idea to ac above the fireplace.

Parrait even that it is a guaranteed cancer.

Other excerpts:

Wood re Beware treated with creosote


Despite strict regulations, the sector of recovery of such wood treated for non-industrial applications remains high.

Creosote, used to protect the rails and wooden poles (SNCF, EDF), is classified as a carcinogen because of its polyaromatic hydrocarbon content.

This is why a warning against the reuse sector, at the limit of legality, is made (a European directive prohibits reuse of creosote for wood for domestic use).

Indeed, many of these treaties and wooden sleepers are still reused by architects or individuals for external works (retaining walls, fence stairs ...).

To address this growing problem, the CTBA is going up, with the support of ADEME, a die for the impregnated wood (creosote, copper, chromium, arsenic).

Creosote, wood tar or beech is a recognized carcinogen.
source: http://astre.scor.com/astrehelp/fr/133q00ww.htm

Restrictions on the use of creosote, deemed dangerous substance. Creosote is a preparation that can be used in particular for the preservation of wood .The Scientific Committee on Toxicity, Ecotoxicity and Environment (CSTEE) highlighted the carcinogenic nature of this preparation, and the fact that it exceeds the limits of the existing legislation, which has led the Commission to adopt a directive prohibiting the sale to consumers of creosote for wood preservation. The ban, which also covers wood treated with creosote, will apply no later than June 30 2003 (press release of October 26 2001).

Good night Rabbit,

Thank you for your answer, but I'm terrified by what you tell me.

I had some time ago, in a room amménagée in the attic, covered the famous beams of two layers of polyester resin, to avoid this unpleasant smell and still maintain the appearance of wood.
Do you think my solution is good?
In the attic part, you think that flaxseed oil is as effective as the resin? and why flaxseed oil? What matters is not it? I thank you in advance for the answer.

Very frankly, I do not think to keep your wood trafficking is a
good idea .The medium-term domestic polution is not perceptible
and yet it is deemed material produced by the inoffensifs.Ce
going discussions of products, the paintings through the carpet, insulation,
perfumes, tapestries etc .. The list is long, chacuns these different
products emetent low doses of toxins that are well recognized
nuisibles.Le made to cover the wood deals with a layer of varnish, even
linseed oil does not seem to me enough .Is that by strong heat
the smell of creosote is still detectable? if c is the case does have a stud.

I am a follower of the linseed oil with drier for the following reason.
The flaxseed oil does not crack over time, unless we apply the layer
Super Thick, and again. It is true that the oil degrades and disappears
quickly asse (al exterior, UV him fatal.ce are prob
n exist inside al) but do not sanding
add one more couche.De the linseed oil is inoffencive (without drying)
even if inadvertently lon leche is a finger souile al linseed oil.

Unlike the patent, the linseed oil saturates the surface of the wood and prevents
dy water penetrate .Cest why I treat the first time the wood with
2 oil layers diluted (with turpentine (50 30% and%) spaced from 6 hours. When the wood is no longer sticky, I treat one last time with oil
has 100% (thin layer) .Then each year, j adds a spring
before the tongs .If a sy fly glue that is not very grave.elle
disappear during the summer with the wear of the oil.

To return to creosote, the linseed oil seems to limit states
DAMAGE because this is huileux.il will therefore be diluted with 1 iere
Linseed oil layer and sy fixer.la 2 th layer to isolate the permettera
treated wood and 1 iere layer of oil (containing creosote which will dilute sy)
from the outside. Ds this case one, wait until the 1 iere layer is well dry
and even hard before applying the 2 ieme.Sinon creosote migration
iere the 1 2 has the ith layer.

NB without the drying linseed oil inside take a eternitee has figer.En
Outside it takes close to 1 months if super sunny weather.

Hello Rabbit,
thank you again for your reply, I was absent last moments ...
Indeed the smell is still noticeable, but the fact how to be sure that it is creosote? How did recognize-you one? For sure these are old telephone poles that were used in the framing 1980 years. When it is very hot in the attic, a tar species ramolit surface and it smells the same as liquid asphalt the roads and bridges put before chipping a road ... What do you think ?

NofyNot very lucky at the moment ...
In addition to the links of Rabbit, I found this on the internet:
http://www.dotapea.com/
Creosote (Greek Kreas, flesh, and sôzein, keep). Oil used to protect wood, mixture of phenols and cresols obtained by distillation of wood.The creosol tar oil is creosote derived from the beech.

Occupational Health / Hygiene
Wooden electric poles
Is the use of creosote always possible?
Creosote is a complex mixture of polycyclic aromatic hydrocarbons (PAHs) and phenolic compounds from the distillation of coal tar. It is mainly used as an agent for protecting wood in industrial and professional applications on a large scale and railway sleepers, electricity and telephone poles, and because of its fungicide and insecticide, its long-term persistence and resistance leaching (rainwater) and degradation by weather. Creosote is classified as carcinogenic category of 2 (probable human carcinogen) by the European Union (EU), including dermal (skin cancer) and inhalation of creosote vapors (lung cancer). Given the toxicity of creosote, its use has been severely restricted by the EU Directive 2001 / 90 / EC of 26 / 10 / 01 transposed in France by the decree of 2 / 06 / 03; creosote is prohibited from marketing to consumers but it can still be used in industrial installations or by professionals in an in situ remedial treatment provided that the benzo-a-pyrene less than 0,005% by weight and that the extractable phenols content by the water is less than 3% by weight.

I discovered today the subject. : Shock:

Again, the media did not do their job in stifling the info so that the business continues. : Evil:

parquet coated carbonyl




by goldmund » 20/09/08, 09:22

Hello everyone, I am a tenant of a house in which the parquet floors of the living room, kitchen and bedroom were coated a long time ago I think of carbonyleum, which not only still gives off very unpleasant odors but also causes very awakenings "foggy" plus all the effects to come ...
I know that the ideal would be to change all the floors of the house but in the meantime would anyone a solution to limit the fumes of the product?
thank you in advance

If you are a tenant, I advise you, but I could be wrong: the temporary installation of a synthetic floor covering of the "balatum" type that you can very easily recover when you move out.

If you opt for the balatum, n no plans to recover.
It will contaminates and contaminant.

In the absence of better ventilated up the apartment.

I think you should consider moving or even better
to declare the insalubrious apartment, this will force the proprios
to do the necessary work.

If t have the means to take first a legal defense insurance
you risk to need. The owner did not let them.
