History of Asbestos Work 
It is interesting to note that the use of asbestos is not a phenomenon of the 19th or 20th century. In fact asbestos has been used since ancient times. It was used to produce such products as clothes and shrouds. It may also have been used to treat skin disease. It is also interesting to note that even in ancient times, some individuals hinted to the adverse effects of asbestos on the health of the individual.

In the nineteenth century asbestos was mainly used as an insulation material. By the mid 20th century asbestos was widely used in various products such as concrete, pipes, fireproof material, roofing and many other products. Asbestos was widely used in shipbuilding and was widely used in World War ll ships. After World War ll it was widely used in Japan to produce ammonium sulphate. Ammonium sulphate was used extensively for many purposes. For many years it was also used in automobile brake pads. However since the mid 1990's brake pads are being made by other safe material.

In the early 1950's Kent cigarettes used asbestos in each filter. Millions of cigarettes were sold and smoked by individuals believing that they were smoking the safest cigarettes on earth. Such individuals were exposed to a very dangerous combination of asbestos and smoking.
Asbestos was one of the major building materials used in the construction of the World Trade Center in New York. After the September 11 attacks thousands of people were exposed to airborne asbestos fibers. The effect of such a large scale exposure will be seen in the future.
