Asbestos is a collection of six silicate minerals that occur naturally. The six minerals have eponymous asbestiform characteristic in common. Each fibrous crystal has microscopic fibrils that total several millions. Abrasion and similar processes make the crystals to release the fibrils into the atmosphere. When in search of asbestos Chicago should be one of the places one considers to visit first.
Asbestos is usually known by its color. There are five main colors of the materials, including white, brown, blue, green, and red. The mining of this material began over 4000 years ago on a small scale. However, at the end of the nineteenth century, mining began to occur on a large-scale. This was caused by the use of the material by builders and manufacturers because of its desirable qualities.
Resistance to heat, electricity and fire, affordability, sound absorption, and average tensile strength are all qualities that led to increase in popularity. The insulation property made the material very useful in insulating homes and electrical components. Ability to resist burning by fire was only possible when the material is mixed into cement or woven to make fabrics or mats.
The qualities named above made the material very popular in the construction industry and in making household as well as industrial appliances. In homes, it was used to make walls and ceiling boards. Popularity continued to rise throughout the twentieth century until when it was discovered that the material caused several medical conditions when inhaled over prolonged periods of time. This made many governments to outlaw the use of the material in construction and many other applications.
Two major types of asbestos exist today. The two categories are serpentine and amphibole and each has various types. Chrysotile is the only individual classified under serpentile. In exists in various places around the world in serpentinite rocks. When observed under microscope, this rock indicates to have white fibers.
In the United States, chrysotile leads in terms of use in all applications. Over 95 percent of all instances where the material is used is chrysotile. Chrysotile can be woven to produce fabric because it is more flexible than amphobile. It dominated in making of roofs, cement, ceilings, floors, walls, and especially in outdoor environments. Additional items that are produced from chrysotile are fire barriers, pipe insulations, high-temperature equipment, brake linings, floor tiles, gaskets, and residential shingles.
Actinolite, tremolite, crocidolite, amosite, and anthophyllite are the varieties classified under the amphobile class. Amosite occurs in large quantities in South Africa where it is also produced on large-scale. It has a brown color. Crocidolite has a fibrous nature and commonly occurs in Australia, Southern Africa, and Bolivia. Crocidolite has a blue color.
It is now public knowledge that asbestos is a carcinogen to people and even animals. There are many serious health hazards that the substance is linked to. Amosite and crocidolite get considered to be the most dangerous to human health. The others are also just as dangerous. Asbestosis and malignant mesothelioma is caused in people by chryotile.
