Common Types of Asbestos Found |
Posted: August 20, 2018 |
Technically speaking, “asbestos” is a commercial and legal term encompassing multiple types of minerals. The Asbestos Hazard Emergency Response Act (AHERA) classifies the asbestiform varieties of the following minerals as asbestos: Chrysotile(white asbestos) is the most commonly used form of asbestos and can be found today in the roofs, ceilings, walls and floors of homes and businesses. Manufacturers also used chrysotile asbestos in automobile brake linings, gaskets and boiler seals, and insulation for pipes, ducts and appliances. Amosite(brown asbestos) was used most frequently in cement sheets and pipe insulation. It can also be found in insulating board, ceiling tiles and thermal insulation products and more on Asbestos. CrocidoliteKnown widely as ‘blue asbestos’ this fibre was voluntarily banned in the UK in 1970. Considered the most dangerous form of commercially used asbestos, Crocidolite fibres are shorty and spikey, meaning then tend to puncture the lining of the lungs causing long-lasting damage. Their spikey shape also mean they are more difficult to breathe out if inhaled. Crocidolite is part of a family of minerals known as Amphiboles, of which Amosite is also a member. The Amphibole family also include Tremolite, Anthophyllite and Actinolite. These additional 3 minerals are also considered dangerous to humans, although they were used far less frequently due to them being much rarer. Crocidolite was mainly used in the UK as a sprayed-on insulation, thermal insulation (pipe lagging), loose-fill insulation, asbestos-woven textiles (such as gaskets) and in cement sheeting. Due to its uses for spray/lagging applications and gaskets, Crocidolite was very common in the marine industry for use on ships for more info visit, Merryhill. Tremolite, Actinolite and AnthophylliteThere are three minor types of asbestos that you may hear about. Tremolite, actinolite and anthophyllite have never been sold commercially. Instead, they were often found as contaminants in commercially sold asbestos products. TremoliteTremolite fibres are often found as a contaminant in chrysotile asbestos and found in paints, sealants, asbestos-containing insulation products and talc products. It can manifest in several colours, including white, green and grey, and is useful as it can be spun and woven into cloth. ActinoliteActinolite fibres are lightweight and generally dark in colour. It comes in various forms, including brittle and fibrous or dense and compact, and is often found in paints, sealants and drywall. Additionally, actinolite expands when heated, making it an effective insulation material. This property has led to actinolite being commonly used as insulation materials and structural fire-proofing. AnthophylliteAnthophyllite fibres are grey-brown in colour, commonly found as a contaminant in composite flooring. While anthophyllite is considered to be non-commercial, it was regularly used in products containing vermiculite and talc, such as talcum powder. Even though most studies suggest that the risk of developing mesothelioma from this type of asbestos is much lower than amosite, chrysotile and crocidolite asbestos, there is still a clear link between anthophyllite and the disease get more info at High Speed Training. Asbestos can harm your with the risk of mesothelioma and can be tough to find out the risk of these kinds of asbestos. You need a great environmental assessment service such as Alpha Environmental to find out if there is a risk of asbestos poisoning.
