In most developed countries, laws and regulations require employers and landlords to notify workers and lease holders about asbestos-containing materials in their areas, especially if their activity might disturbe the asbestos. If asbestos is present in building materials, it is not a hazard unless disturbed and turned into airborne dust. It is not possible to look at a material with the naked eye and tell whether asbestos is present. If you know something of the history of a building and understand what kinds of uses asbestos was put to at different times during the last 150 years, it is possible to tell by looking that something might contain asbestos and should be handled as if it did until lab tests show that it does not.
Steve McQueen got mesothelioma from dealing with asbestos while he served in the military. McQueen served in the Marine Corps from 1947 until 1950. In that time, he removed asbestos lagging from pipes aboard a ship, causing his exposure. He was also likely exposed to it during his acting career on sound stages that used asbestos.
Asbestos is avoided because his carcinogenic properties.
Before it was banned in the late 1970's, asbestos siding was installed on several hundred thousand houses within the United States. The asbestos is not a harmful health risk unless the siding is cracked, damaged or deteriorating. Inspect the siding regularly and replace any damaged tiles with non-asbestos versions. Should the siding have to be removed, it should be done by a professional who will follow all applicable ordinances regarding the handling and disposal of asbestos containing products. This is necessary because the dust created during removal may be laced with asbestos which can enter the lungs and cause mesothelioma.

However, the mining operations led to severe health issues for the miners and residents due to asbestos exposure.
The link between mesothelioma and asbestos was established during the late 1920's. These two rare diseases caused a lot of legal and medical disturbances during those times.
Asbestos has been used for thousands of years, with evidence of its use dating back to ancient civilizations such as the Greeks and Romans. However, industrial-scale mining and use of asbestos began in the late 19th century during the Industrial Revolution.
Whether you have asbestos containing material can only be determined by a laboratory test.Asbestos was used in floor coverings, adhesives (that is mastic) and in vapor barrier materials during the 1970s and early 1980s.You should avoid disturbing the material as asbestos is hazardous when INHALED. Contact a qualified asbestos surveyor. It is not possible to identify asbestos simply by visual examination. A sample f the material in question must be properly collects and assessed by a laboratory to determine whether or not it contains asbestos.

Asbestos was commonly used in building construction between the 1940s and 1970s, with peak usage in the 1970s. Buildings and structures constructed during this period are more likely to contain asbestos-containing materials.
At one time, asbestos was incorporated into many building materials because it added strength, heat insulation, chemical resistance, and inability to burn to the products that contained it. Buildings built during that period may have included a lot of asbestos-containing materials.
