Brown asbestos, also called Amosite, is often described as one of the most hazardous forms of asbestos. Working with it for long enough without protection can certainly result in cancer, although probably not sarcosis.
No one should ever work in dusty environments that include airborne asbestos of any type, unless substantial personal protection is used, including respirators, disposable clothing, tools dedicated to the contaminated work area, showers with filtered drains, etc., etc.

What is the group name of asbestos?
Chrysotile asbestos (White) is a Serpentine, Amosite (Grunerite) (Brown asbestos, and Crocidolite (Blue) are Amphiboles
What type of asbestos is corrugated asbestos roofing?
Corrugated asbestos typically contains White (Chrysotile) asbestos at between 10 to 15 % content, however some older materials can contain Blue and Brown at varying content.
What chemicals are used in asbestos?
Asbestos is a naturally occurring mineral, it is formed from: White asbestos (Chrysotile) Mg3(Si2O5)(OH)4, Brown Asbestos (Amosite/Grunerite), Fe7Si8O22(OH)2 Blue Asbestos (Crocidolite), Na2(Fe,Mg)5Si8O22(OH)2
What is asbestos-cement cladding?
Asbestos cladding is a general construction sheeting formed from the mixture of a natural cement and asbestos. It makes a good weather proofing material at low cost. The asbestos content could be as high as 30% Chrysotile (White asbestos). Some cladding sheets have been found with smaller levels of Blue and Brown asbestos or a mixture of all three.

What does asbestos look like?
Asbestos is a mineral that can appear in different forms, such as long, thin fibers or bundles of fibers. It can be white, gray, brown, or blue in color.
What is the chemical formula of asbestos?
It depends on the type: Chrysotile (White), Mg3(Si2O5)(OH)4 Amosite/Grunerite (Brown) Fe7Si8O22(OH)2 Crocidolite (Blue) Na2(Fe,Mg)5Si8O22(OH)2
What color asbestos was most commonly used in building products?
The most commonly used type of asbestos in building products is chrysotile, also known as white asbestos. Chrysotile accounted for the majority of asbestos used in construction materials, including insulation, roofing, and flooring. Other asbestos types, like amosite (brown asbestos) and crocidolite (blue asbestos), were used less frequently. However, due to health risks associated with asbestos exposure, its use has been heavily regulated or banned in many countries.
What does asbestos look like and how can it be identified?
Asbestos is a mineral that appears as a fibrous material in various colors like white, gray, or brown. It can be identified through professional testing or inspection of building materials for its presence.
What years were asbestos in building materials?
Asbestos was commonly used in building materials from the 1940s to the 1970s. Its use began to decline in the late 1970s before being banned in most construction materials in the 1980s and 1990s due to its health risks.
What does asbestos look like?
Asbestos is a fiberous mineral. It is hard to describe its appearance but white asbestos has a look similar to cotton wool, whereas brown and blue asbestos look similar to crushed timber but on a much much smaller scale. It is not possible to look at a manufactureed product with the naked eye and determine whether it contains asbestos. An experienced minerologist might be able to identify raw, unprocessed asbestos by sight, but where exposure and health is a concern, lab analysis should be relied upon.
What colour of asbestos is used in building products?
There are a number of forms of asbestos that can be called by a colour, but can also be called by their actual mineralogical or trade name. White asbestos, which is more properly called Chrysotile, was widely used in building products and is the most commonly found type of asbestos in building materials today. However, other types have also been used. Brown asbestos, more widely known by its trade name, Amosite, is the second most commonly found asbestos type in building products.
