Why is Azbest so controversial?

controversy above asbestos has arisen because it has been shown that certain types of asbestos cause serious health problems such as cancer, but it is a cheap and efficient insulator already installed in countless buildings. A study of health threats represented by the spray versus pre -created asbestos in recent decades have controversial results. Some people conclude that this product should be disabled while others insist that they can be installed and maintained with minimal danger. People still have misconceptions after a highly promoted controversy, but a large part of their concerns is guaranteed. For ten years, those who mined and installed it had to be damaged, it turned out that people had become ill for airway diseases such as asbestosis, and began to die of lung cancer called mesotheliom. Early, extensive medical studies, according to litigation, narrowed the cause of death and found that asbestos of certain varieties cause cancer only crumb or spraythe asbestos of certain varieties. At the beginning of the 90s, the institute for the effects of healthcare and the environmental protection agency published that the fibers of this material must be before entering the respiratory system in the air. Removing a crumbly asbestos would therefore all eliminate related conditions.

manufacturers have denied that the controversial asbestos use was so dangerous that it requires it to be eliminated and excluded from the structure. They started using a chrysotile asbestos to create insulating tiles in the factory and be transported to the construction site. With this change, the worst risk of cancer was reduced to perhaps affecting miners and factory workers, but it was not dangerous for a common population occupying trading or residential buildings. The plans were made to make other similar products to eliminate other products, supported by less robust scientific evidence in the age of 90, to facilitate people's distrust.

When it comes to crumbly and chrysotile asbestos, which has already been installed, there was a controversy about whether the isolation in old buildings could disintegrate and re -release dangerous dust that could be inhaled and cause cancer. Some people again believed that it was more destructive to disrupt the tile of building buildings because it separates the threads. Others, including many European experts, wanted to eliminate all cases of crumbly asbestos by costly demolition. The consensus in the controversy in America was achieved by introducing strict schedules of maintenance of buildings isolated asbestos, instead of demolition. Experts also considered the danger that lives would lose fire using less effective isolation, which was estimated as a larger number than the lives threatening asbestos.
