asbestos

 [as-bes´tos]
fibrous calcium and magnesium silicate, a nonburning compound used in roofing materials, insulation for electric circuits, brake linings, and many other products that must be fire resistant. Alternative materials are being developed to replace asbestos because fine asbestos fibers can be inhaled, causing asbestosis, pleural mesothelioma, and other types of lung cancer. In 1971, asbestos became the first material to be regulated by the Occupational Safety and Health Administration.

as·bes·tos

(as-bes'tŏs), Avoid the mispronunciation as-bes'ōz.
The commercial product, after mining and processing, obtained from a family of fibrous hydrated silicates divided mineralogically into amphiboles (amosite, anthrophyllite, and crocidolite) and serpentines (chrysotile); it is virtually insoluble and is used to provide tensile strength and moldability, thermal insulation, and resistance to fire, heat, and corrosion; inhalation of asbestos particles can cause asbestosis, pleural plaques, pleural fibrosis, pleural effusion, mesothelioma, and lung cancer.
[G. unquenchable; so-called in the erroneous belief that when heated, its warmth could not be quenched]

asbestos

An incombustible mineral fibre once widely used in industry and commercial products (the USA, for example, used 30 billion tons of asbestos since 1900), such as insulation, brakes, fire-proofing, etc., prolonged overexposure to which may lead to asbestosis and possibly cancer.

Maximum exposure levels (1976 OSHA standard)
2 fibres/cm3/8 hours.

asbestos

Environment Any finished natural product containing a type of incombustible mineral fiber; the US has used 30 billion tons of asbestos since 1900; it is a component of ± 3000 manufactured products; maximum exposure levels–1976 OSHA standards = 2 fibers/ccm3/8 hr period

ASBESTOS

(as-bes'tŏs)
Acronym used in assessing casualties from chemical (and radiologic) agents. The components of the acronym are A for agent (type of chemical or radiation); S for state (e.g., solid, liquid, gas, vapor, aerosol); B for body site, or route of exposure (e.g., inhalational, percutaneous, ocular, enteral, parenteral); E for effects (local vs. systemic); S for severity of effects and of exposure; T for time course (e.g., time from exposure, length of latent period, prognosis); O for other diagnoses (both instead of and in addition to the agent originally considered); and S for synergism (interaction among multiple diagnoses).

as·bes·tos

(as-bes'tŏs)
Product obtained from fibrous hydrated silicates divided into amphiboles and serpentines; it is insoluble and is used to provide tensile strength and moldability, thermal insulation, and resistance to fire, heat, and corrosion; inhalation of asbestos particles can cause asbestosis and cancer of the lung and pleura.
[G. unquenchable; so-called in the erroneous belief that when heated, its warmth could not be quenched]

Asbestos

A naturally occurring mineral, utilized worldwide for its durability and heat resistant qualities. Extremely fibrous in nature, asbestos particles can easily enter the respiratory system and damage sensitive tissue. This damage can result in asbestosis, mesothelioma, and lung cancer.

Patient discussion about asbestos

Q. Why have i been seeing so many commercials regarding asbestos related mesothelioma? I have been quite curious to know why law firms are pushing mesothelioma ads.

A. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.The liability resulting from the sheer number of lawsuits and people affected has reached billions of dollars.The amounts and method of allocating compensation have been the source of many court cases, reaching up to the United States Supreme Court.
so where ever there's money- there's lawyers..
