In Soviet times, with the coating of playgrounds, they practically did not bother. The standard was simple river sand, concrete tile, asphalt or, most often, grass. Fell from the bicycle, abandoned the knee, the styling of blood and snot, stuck the Plate of the plantain and went further.
The main thing is that the parents do not drive home!
And the knee will heal. Before wedding 100%
Today, the coating of playgrounds are approaching responsible. Do not give God the child to the knee hurts because of the wrong material, it is possible to get on the court. Therefore, municipalities and commercial enterprises are reinsured — apply the materials of the softer.
One of these «soft» materials, which is considered not attendable, is a rubber coating. His victorious procession in the country, this miracle material began not so long ago. 5 years ago, almost no one knew about him.
When I put such a tile for the first time in our city, many residents approached, raised the tile, almost tasted. One pensioner, apparently by system habit, tried to take a few tiles to his garden in the evening, caught in time.
But now in any square, there is such a tile on every playground and no one is surprised. Accustomed.
There was a rubber tile and in private homes — many want to shift the space in front of the house. It is very convenient — it does not crack, it does not break, it does not crumble — a dream, not the material. The only thing that strains is the price. Compared to a blocking, it turns out to be expensive, although they make it from waste — old tires and polyurethane glue.
Between in Europe countries to laying rubber tiles, it is suitable more carefully: it is not put not only in private houses, but also in playgrounds.
The reason for the refusal of European countries from this miracle material is its harm.
Our domestic GOST 12.1.007-76 rubber coating refers to the 4th class of danger. That is, for health, if not there is its kilograms and do not burn in the oven, it will not harm. To get poisoning from it, you need to put the whole house from the inside of rubber and live in it not one ten years.
So why cautious Europeans concluded that the tile is harmful to health?
Everything is very simple!
Hurting from tile does not appear immediately, but for 3-5 years of its use. Rubber coating, like a sponge, absorbs all pollution, plenty of gasoline and oil, car exhaust, emissions of enterprises. In short, all the inclination that surrounds us. After a few years, the rubber turns out to be naked all under the string and begins to give it back.
The fact is that laboratory tests are carried out at a temperature of 18 — 22 degrees. With this temperature there is no harm. The situation changes dramatically when the tile turns out to be on the «fresh» air and on top of it will cake affectionate sun. And what kind of gentle can be the sun, this year has learned many, for example, we recently stood the heat +36 in the shadow, + 43 in the sun, and the surfaces of objects, houses and sites including glow up to +72. Many cotton saidding at home!
Do you know what kind of smell stood on playgrounds with rubber crumb?
In the sun, rubber coating fraudes with all the «colors» of the chemical rainbow: products of rubber destruction (monomers) are distinguished from the tile, and this is wherever very toxic chemical compounds. Plus climb aromatic hydrocarbons; Benzole, toluene, xylene, styrene, formaldehyde, phenols, benzpins. The whole cocktail is entirely and in particular is the cause of tumors (the report of the International Cancer Research Organization — IARS).
By the way, it turned out that the rubber coating is not so injurious. On such a tile, you can handle the knee more abruptly than on asphalt.
So in Europe it is allowed to use tiles from rubber crumbs on small sites (up to 10 kV / m), before entering public spaces, on steps, on open sports grounds for skates, rollers, bicycles.
On large open and even more closed playgrounds, its use is not recommended.
Do you know how the arch of the European rules of urban improvement prescribes close playgrounds?
Mytoy river sand!
It turns out that Europe returned to the fact that 20 years ago was in each of our yard — to the sand. We all get ahead in an attempt to catch up or overtake someone.
Maybe you should not drive horses, but look back and take into account the experience of the past. What do you think?
