The 3 Most Significant Disasters In Asbestos Attorney History

The Dangers of Exposure to Asbestos

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

It is impossible to tell just by looking at something if it contains asbestos. It is also impossible to smell or taste it. It can only be found when asbestos-containing materials are chipped, drilled or broken.

Chrysotile

At its peak, chrysotile made up for 95% of the asbestos that was produced. It was widely used in industries, including construction insulation, fireproofing, and construction. Unfortunately, if workers were exposed to the toxic substance, they could develop mesothelioma, as well as other asbestos-related diseases. Fortunately, the use this dangerous mineral has decreased drastically since mesothelioma awareness started to grow in the 1960's. It is still present in a variety of products we use today.

Chrysotile is safe to use when you have a thorough safety and handling program in place. People who handle chrysotile do not exposed to a significant amount of risk at the current controlled exposure levels. Lung fibrosis, lung cancer and mesothelioma were all linked to breathing airborne respirable fibres. This has been confirmed both for intensity (dose) as well as duration of exposure.

In one study, mortality rates were compared among a factory which used almost exclusively Chrysotile in the production of friction materials and national death rates. It was discovered that, for 40 years of preparing asbestos chrysotile at a low level of exposure, there was no significant excess mortality in this factory.

In contrast to other forms of asbestos, chrysotile fibres tend to be shorter. They can pass through the lungs and enter the bloodstream. They are more likely to cause health problems than fibres with longer lengths.

When chrysotile mixes with cement, it's extremely difficult for the fibres to be airborne and pose any health risk. Fibre cement products have been extensively used all over the world particularly in structures such as schools and hospitals.

Studies have shown that chrysotile is less prone to cause illness than amphibole asbestos, such as crocidolite and amosite. Amphibole types like these are the main cause of mesothelioma and other asbestos-related diseases. When cement and chrysotile mix together, a strong product is produced that is able to stand up to extreme weather conditions and environmental hazards. It is also simple to clean after use. Asbestos fibres are easily removed by a professional and removed.

Amosite

Asbestos refers to a set of silicate mineral fibrous which are found naturally in a variety of types of rock formations. It is composed of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973).

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

Asbestos was heavily used in the early two-thirds of the 20th century to construct construction of ships as well as insulation, fireproofing and other construction materials. The majority of asbestos-containing exposures to the workplace were in the air, however some workers also were exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry to industry, era to era and even geographical location.

Most asbestos exposures that workers were exposed to was due to inhalation, but certain workers were exposed by skin contact or through eating contaminated food. Asbestos can only be found in the natural environment due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles as well as car brakes and clutches, and insulation.

There is evidence emerging that non-commercial amphibole fibers could also be carcinogenic. These fibres are not tightly weaved like the fibrils in serpentine and amphibole, they are loose and flexible, and needle-like. They can be found in mountains, sandstones, and cliffs from a variety of nations.

Asbestos is able to enter the environment in a variety ways, including as airborne particles. It is also able to leach into water or soil. This can be triggered by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination in surface and ground waters is primarily caused through natural weathering. However it is also caused by humans, such as through the mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping material in landfills (ATSDR 2001). The inhalation of asbestos fibers is the primary reason for illness among those exposed to it occupationally.

Crocidolite

Inhalation exposure to asbestos is the most frequent way people are exposed to the dangerous fibres, which can then enter the lungs and cause serious health issues. These include mesothelioma and asbestosis. Exposure to asbestos fibres can occur in different ways, including contact with contaminated clothes or building materials. This kind of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are thinner and more fragile which makes them more difficult to breathe in. They can also lodge deeper inside lung tissue. It has been associated with more mesothelioma cases than other asbestos types.

The main types are chrysotile as well as amosite. Amosite and chrysotile are the most frequently used types of asbestos and make up 95% of all commercial asbestos in use. The other four types haven't been as widely used however they can be present in older buildings. They are less dangerous than amosite and chrysotile, but they can pose a risk when mixed with other asbestos minerals or when mined close to other mineral deposits, like talc or vermiculite.

Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. The evidence isn't unanimous. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95 percent range of CI: 0.7-3.6) for all workers exposed to asbestos while other studies have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for those working in chrysotile mines and mills.

IARC, the International Agency for Research on Cancer has classified all forms of asbestos as carcinogenic. All types of asbestos can cause mesothelioma or other health issues, although the risks vary according to how much exposure people are exposed to, the kind of asbestos used as well as the length of their exposure and the way in the way that it is breathed in or ingested. IARC has stated that the best choice for individuals is to avoid all types of asbestos. However, if someone has been exposed to asbestos in the past and suffer from an illness, such as mesothelioma and other respiratory conditions, they should seek guidance from their physician or NHS 111.

Amphibole

Amphiboles are a collection of minerals which can form prism-like or needle-like crystals. They are a type of silicate mineral made up of double chains of molecules of SiO4. They have a monoclinic arrangement of crystals, however some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. Double chains contain (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. The tetrahedrons are separated one another with octahedral strips.

Amphibole minerals can be found in metamorphic and igneous rocks. They are typically dark-colored and tough. Due to their similarity of hardness and color, they can be difficult for some people to differentiate from pyroxenes. They also share a corresponding design of cleavage. However their chemistry permits many different compositions. The chemical compositions and crystal structures of the different minerals in amphibole can be used to identify them.

Amphibole asbestos includes chrysotile and the five types of asbestos: amosite, anthophyllite (crocidolite) amosite (actinolite) and amosite. While the most popular form of asbestos is chrysotile; each has its own unique characteristics. Crocidolite is considered to be the most hazardous asbestos type. It is made up of sharp fibers that can be easily inhaled into the lung. Anthophyllite comes in a brownish-to yellowish color and is made mostly of iron and magnesium. This type of stone was once used in products like cement and insulation materials.

Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions.  pearland asbestos attorney  of the composition of amphibole minerals is a complex process that requires specialized methods. EDS, WDS and XRD are the most common methods of identifying amphiboles. These methods can only provide approximate identifications. For instance, these methods cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende and pargasite.
