Preserved and unopened asbestos is harmless. However, asbestos fibers may become entangled in the air when the asbestos-containing box is broken or damaged. In this case, asbestos is a danger to you and those around you.
Use of Asbestos varies depending on how you use it.
At Work: Always comply with existing rules and regulations when handling asbestos-containing materials. (You can learn the rules and regulations of the institution you work with and the safety instructions that come with the material you will use. You will not only be punished if you fail to comply with these rules and regulations, but also endanger your own health and those around you.)
On site: Contractors and site supervisors must follow certain rules regarding the use of asbestos.
At home: Although there is no regulation about the use of asbestos at home, you should be careful about the health of you and those around you and carefully read and apply the safety rules.
The word asbestos is a general term for a group of silicate minerals with similar ingredients. These features can be listed as:
- They have fine fiber crystals which can be broken and dispersed quickly
- Resistant to fire, heat and electricity
- They absorbe sound
Although all types of asbestos share these ingredients, they differ in their colors and tensile strength.
Asbestos is the most common and still the only type extracted as a mine. It has been widely used in developed countries. It is estimated that between 90 and 95 percent of the asbestos found in the buildings of the United States and Canada is chrysotile asbestos.This wide use of it, has made this variant of asbestos the leadear in health problems of caused by asbestos. However, companies that continue to remove chrysotile asbestos as mines trying to prove that it is not a health hazard. One of the most frequently used areas of chrysotile is fire resistant materials and insulation materials. Therefore it was widely used in ships of the United States Navy during the Second World War and the Korean War.
It has a coffee colour and is a commercial product of amosit. It has disappeared in the last decade and is no longer mined by the mining firms. However in the past, asbestos was the second most commonly used type. Therefore, many people have been exposed to it when amosit asbestos was frequently used. Amosit is also used as an insulation material in factories and buildings and it has been used because of their acoustic and density diluent nature. Many countries have prohibited the use of amosit asbestos in the last 30 years.
Crocidolite asbestos constitutes 4 percent of the asbestos used in the United States in the past. Crocolite naturally occurs in long, sharp and flat packs. Blue cyanitol asbestos is harder and brittle compared to the other asbestos. It can be easily broken and can spread easily inhalable fiber that are needle-shaped. Without no doubt, crocidolite is the most deadly of asbestos varieties. It is generally used in the production of yarn and rope. Increasing the durability of plastics is also usage areas of crocidolite asbestos.
Tremolite asbestos, which is an amphibole of asbestos fibers, causes malignant mesothelioma and other asbestos-induced cancers. Like other types of asbestos, tremolite asbestos also contains a large proportion of magnesium. It can be found in various colors from dirty white to green. It is found especially in vermiculite deposits. Tremolite-infected vermiculites has costed in hundreds of miners’ lives.
Actinolite asbestos also belongs to the subclass of amphibole asbestos, and therefore its appearance and structure is similar to other amphibole asbestos. Magnesium in it is dense and its quite rare in the nature. The color of it may vary from white to dark brown. Although they are not used in asbestos-containing products due to their rarity, Actinolite asbestos can be found in metamorphic rocks. They are carcinogenic like other asbestos types and cause mesothelioma cancer.
It is also called brown asbestos and its structure is concentrated in iron and magnesium elements. Its fibers are known as long and flexible. Brown asbestos subfamily is found in the brown asbestos talc mines and is indicated among the causes of some respiratory diseases. No definitive links has been found out in mesothelioma and other asbestos species. Some types of cement and insulating materials also include anthophyllite asbestos.
