Asbestosis is the scarring of lung tissue (beginning around terminal bronchioles and alveolar ducts and extending into the alveolar walls) resulting from the inhalation of asbestos fibers. There are two types of fibers: amphibole (thin and straight) and serpentine (curly).
Widespread recognition of the occupational risks of asbestos in Britain was reported in 1924 by a Dr. Cooke, a pathologist, who introduced a case description of a 33-year-old female asbestos worker, Nellie Kershaw, with the following: "Medical men in areas where asbestos is manufactured have long suspected the dust to be the cause of chronic ...
Asbestos abatement. Weathered fibrous asbestos sheeting showing loose fibres. In construction, asbestos abatement is a set of procedures designed to control the release of asbestos fibers from asbestos-containing materials. [1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when ...
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a naturally occurring, carcinogenic, fibrous silicate mineral.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into the atmosphere by ...
The mineral asbestos is subject to a wide range of laws and regulations that relate to its production and use, including mining, manufacturing, use and disposal. [1][2][3] Injuries attributed to asbestos have resulted in both workers' compensation claims and injury litigation. [4][5] Health problems attributed to asbestos include asbestosis ...
Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma. People who worked in jobs with high asbestos dust exposure are at the highest risk ...
Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet"; but different from the natural mineral fibrolite), or AC sheet, is a composite building material consisting of cement and asbestos fibres pressed into thin rigid sheets and other shapes. Invented at the end of the 19th century, [1] the material was ...
Asbestos shingles are roof or wall shingles made with asbestos cement board. They often resemble slate shingles and were mass-produced during the 20th century as these were more resilient to weathering than traditional slate shingles for the reason that slate is very soft and prone to weathering. Due to health risks of asbestos products, the ...
