Asbestos has been known of and used for over 2000 years but it was not until the start of the 20th Century that it was recognised as causing disease. From the early 1900's asbestos has been widely used across a range of industries, including shipbuilding, railways and the construction industry. Many types of industrial workers (car mechanics, laggers, electricians, plumbers, roofers, ship builders and carpenters) are now at high risk of developing asbestosis or a related condition.
Once asbestos fibers become disturbed and air borne, they can be breathed into the lungs by occupants of a building. People working with the substance, for example by drilling holes into walls or removing old insulations, are significantly at risk. Asbestos fibers irritate the lungs, resulting in fibrosis: the scarring and thickening of tissue that can cause the lungs to lose some of their elasticity. Even a very small amount of exposure to asbestos can cause mesothelioma, a fatal cancer caused only by asbestos. Many asbestos-related illnesses can take a number of years to develop.
