Asbestos Attorney: The Good, The Bad, And The Ugly

The Dangers of Exposure to Asbestos

Asbestos was used in a variety of commercial products prior to when it was banned. Research shows that exposure to asbestos can cause cancer and other health issues.

It is difficult to tell by looking at something if it's made of asbestos. Also, you cannot smell or taste it. It is only visible when asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At its height, chrysotile was responsible for 99% of the asbestos made. It was widely used in industries, including construction insulation, fireproofing, and insulation. If workers are exposed to asbestos, they could develop mesothelioma and other asbestos-related diseases. Thankfully, the use of this harmful mineral has diminished significantly since mesothelioma awareness began to grow in the 1960's. However, trace amounts of it are still present in many of the products we use in the present.

Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. Chrysotile handling workers aren't at risk of being exposed to a high degree of risk based on the current safe exposure levels. Lung cancer, lung fibrosis and mesothelioma were all linked to breathing in airborne respirable fibres. This has been proven for the intensity (dose) as in the time of exposure.

One study that looked into an industrial facility that used almost exclusively chrysotile for manufacturing friction materials compared mortality rates in this factory with national death rates.  clifton asbestos lawyer  was concluded that for 40 years of processing asbestos chrysotile at a low level of exposure, there was no significant excess mortality in this factory.

Chrysotile fibres tend to be shorter than other types of asbestos. They can enter the lungs, and enter the bloodstream. They are more likely to cause health problems over longer fibres.

When chrysotile mixes with cement, it's extremely difficult for the fibres to air-borne and pose health risks. Fibre cement products are extensively used in a variety of locations around the world including hospitals and schools.

Research has shown that chrysotile has a lower chance to cause illness than amphibole asbestos like crocidolite and amosite. These amphibole forms have been the primary cause of mesothelioma and various asbestos-related diseases. When cement and chrysotile are mixed, a durable and flexible product is created that is able to stand up to extreme environmental hazards and weather conditions. It is also easy to clean after use. Asbestos fibres are easily removed by a professional and removed.

Amosite

Asbestos is a category of fibrous silicates found in certain types of rock formations. It is divided into six groups which include amphibole (serpentine) and the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals comprise long, thin fibers that range in length from fine to broad. They can also be curled or straight. They are found in nature as individual fibrils, or as bundles with splaying ends called a fibril matrix. Asbestos minerals can be found in powder form (talc) or mixed with other minerals and sold as talcum powder and vermiculite which are widely used in consumer products like baby powder cosmetics, face powder and baby powder.

Asbestos was used extensively in the first two thirds of the 20th century to construct construction of ships insulation, fireproofing, insulation and various other construction materials. Most occupational exposures were asbestos fibres in the air, however some workers were exposed contaminated vermiculite or talc as well as to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied from industry to industry, from era to and also from geographical location.

Most of the asbestos-related exposures in the workplace were due to inhalation, but certain workers were exposed through contact with skin or through eating contaminated food. Asbestos is now only found in the natural weathering of mined ores and the deterioration of products contaminated with asbestos like insulation, car brakes and clutches and ceiling and floor tiles.

There is emerging evidence that non-commercial amphibole fibers could also be carcinogenic. These fibers aren't tightly knit like the fibrils found in amphibole and serpentine they are loose as well as flexible and needle-like. These fibres are found in the mountains and cliffs of several countries.

Asbestos is absorbed into the environment mostly as airborne particles, but it can also leach into water and soil. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination of ground and surface water is largely associated with natural weathering. However, it has also been caused by anthropogenic activities such as milling and mining demolition and dispersal of asbestos-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR, 2001). Airborne asbestos fibres are the main cause of illness in people exposed to it in their occupation.

Crocidolite

Inhalation exposure to asbestos is the most frequent method by which people are exposed to harmful fibres, which could then get into the lungs and cause serious health problems. Mesothelioma as well as asbestosis and other diseases are all caused by asbestos fibres. Exposure to the fibres can occur in different ways, like contact with contaminated clothing or building materials. The dangers of exposure are greater when crocidolite, the blue form of asbestos, is involved. Crocidolite fibers are smaller and more fragile which makes them more difficult to breathe. They also can get deeper inside lung tissue. It has been linked to a larger number of mesothelioma related cases than any other form of asbestos.

The six primary types are chrysotile, amosite and chrysotile. The most common forms of asbestos are chrysotile and epoxiemite, which together make up the majority of commercial asbestos employed. The other four types haven't been as widely used, but they may still be present in older buildings. They are less dangerous than amosite or chrysotile, but they can still pose a threat when mixed with other minerals, or when mined close to other mineral deposits like vermiculite and talc.

Numerous studies have shown that there is a link between stomach cancer and asbestos exposure. The evidence is not conclusive. Some researchers have reported an SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for workers in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, however, the risk is dependent on how much exposure, the type of asbestos is involved and how long exposure lasts. The IARC has recommended that avoid all forms of asbestos should be the top priority since this is the most secure option for those who are exposed. However, if a person has been exposed to asbestos in the past and are suffering from a condition such as mesothelioma or other respiratory ailments, they should seek guidance from their physician or NHS 111.

Amphibole

Amphiboles are groups of minerals that may form needle-like or prism-like crystals. They are a type of inosilicate mineral that is composed of two chains of SiO4 molecules. They typically have a monoclinic crystal system however, some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 tetrahedrons that are linked in rings of six. The tetrahedrons are separated by strips of octahedral site.

Amphiboles can be found in both igneous and metamorphic rock. They are typically dark-colored and hard. They can be difficult to distinguish from pyroxenes as they share similar hardness and color. They also share a corresponding the cleavage. Their chemistry allows for a range of compositions. The chemical compositions and crystal structure of the different minerals in amphibole can be used to determine their composition.

The five types of asbestos that belong to the amphibole group include amosite, anthophyllite as well as crocidolite and actinolite. While the most frequently used form of asbestos is chrysotile, each variety is unique in its own way. The most hazardous type of asbestos, crocidolite, is made up of sharp fibers that are easy to breathe into the lungs. Anthophyllite can range from yellow to brown in color and is made up of iron and magnesium. This type was used to make cement and insulation materials.

Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions. A thorough analysis of the composition of amphibole minerals is a complex process that requires specialized techniques. The most widely used methods for identifying amphiboles is EDS, WDS, and XRD. These methods can only provide approximate identifications. For instance, these techniques cannot differentiate between magnesio hornblende and hastingsite. Additionally, these techniques do not distinguish between ferro hornblende and pargasite.
