Asbestos professionals are trained to use special sheeting and HEPA air filtration devices to aid in safe disposal. In addition to removing this toxic substance, asbestos abatement businesses can do other jobs such as identify possible asbestos-containing materials, test for the substance, draft a removal and disposal plan, as well as remove the substance itself.

Asbestos was mined in Wittenoom, a remote town in Western Australia. The asbestos mine in Wittenoom operated from 1943 to 1966, and during that time, large quantities of blue asbestos, also known as crocidolite, were extracted. 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 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.

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.
