Asbestos

About Asbestos

Asbestos is the only known cause of mesothelioma. Asbestos is a combination of several minerals held together by silky strands of fibers. These fireproof fibers do not burn, and do not conduct heat or electricity. Because asbestos does not conduct heat well and is resistant to melting or burning, asbestos was used widely in all types of construction products up to the mid-1970s. Other products made with asbestos, such as insulation materials and automotive clutches and brakes, were designed principally to contain heat and sound.

Mesothelioma Chrysotile

Chrysotile asbestos is the main cause of malignant pleural mesothelioma. The three most common forms of asbestos are chrysotile, amosite, and crocidolite. Chrysotile or white asbestos accounts for approximately 95% of the asbestos used in US production of asbestos products and is the only member of the serpentine group of minerals.

Direct exposure to asbestos

The risks of developing mesothelioma increase with the intensity and duration of asbestos exposure. Most persons who develop mesothelioma were directly exposed to asbestos at their jobs for long periods of time. Following are a list of some of the higher risk jobs:

Occupations:

Auto Mechanics – at risk of developing mesothelioma because brake pads and clutches contained asbestos
Boiler makers – at risk of developing mesothelioma because asbestos insulation was wrapped around the boilers
Bricklayers – at risk of developing mesothelioma because certain bricks, most notably firebricks, contained asbestos
Building Inspectors – at risk of developing mesothelioma from regular exposure to construction sites containing asbestos
Carpenters – at risk of developing mesothelioma because flooring, roofing, insulation, and joint compound contained asbestos
Drywallers – at risk of developing mesothelioma because joint compound contained asbestos
Electricians - at risk of developing mesothelioma because electrical wiring coverings contained asbestos and because often were required to cut insulation to do work
Furnace Workers - at risk of developing mesothelioma because insulating firebrick and gunnite contained asbestos
Glazers – at risk of developing mesothelioma because glazing equipment contained asbestos material
Grinders – at risk of developing mesothelioma because grinding equipment contained asbestos material
Insulators – at risk of developing mesothelioma because virtually all insulation products contained asbestos
Iron workers– at risk of developing mesothelioma because insulating firebrick and gunnite contained asbestos
Laborers – at risk of developing mesothelioma to the extent they performed same work as tradesman exposed to asbestos
Longshoremen – at risk of developing mesothelioma because insulation of ships’ boilers contained asbestos
Maintenance workers – at risk of developing mesothelioma to the extent job sites contained asbestos
Merchant marines – at risk of developing mesothelioma because insulation of ships’ boilers contained asbestos
Millwrights – at risk of developing mesothelioma to the extent various trades performed by millwright exposed them to asbestos
Miners - at risk of developing mesothelioma because of working in old iron-ore mines exposed them to asbestos.
Operating Engineers– at risk of developing mesothelioma because insulation of pipes contained asbestos
Painters– at risk of developing mesothelioma to the extent they painted in areas containing asbestos products
Plasterers – at risk of developing mesothelioma because joint compound contained asbestos
Plumbers – at risk of developing mesothelioma because pipes were insulated with asbestos material
Roofers – at risk of developing mesothelioma because roofing tiles contained asbestos
Sand blasters– at risk of developing mesothelioma to the extent they blasted metals containing asbestos products and in areas containing asbestos products
Steam or pipe fitters – at risk of developing mesothelioma because insulation of boilers and furnaces contained asbestos
Tile setters – at risk of developing mesothelioma because tiles contained asbestos
U.S. Navy veterans – at risk of developing mesothelioma because boilers were insulated with asbestos material
Welders – at risk of developing mesothelioma because welded through or cut pipes wrapped with asbestos material

Secondary exposure to asbestos

Although much less common, family members of persons working at high-risk jobs may also have been exposed to asbestos. Generally, this exposure occurs when the person with direct exposure bring home asbestos fibers on his work clothes.

Although unlikely as well, persons working in buildings constructed before the mid-1970s, such as school buildings and hospitals, may be at risk if asbestos fibers from the insulation become airborne. Because much of the asbestos in these buildings has been removed or remediated, the risks today are much lower.

Compensation from the Asbestos Industry

For decades, many of the manufacturers of asbestos and asbestos-containing products were aware of the hazards of asbestos, such as the development of mesothelioma, but failed to warn workers or the public of these dangers. As a result, most persons who develop mesothelioma are entitled to compensation from the asbestos industry for their injuries.
