Use of asbestos in the 20th century

Although the Greeks and Romans, noted lung problems in minor asbestos and slaves who wore asbestos fibres, we continued to use the equipment for the majority of the 20th century. Unfortunately, today, we know that asbestos causes problems of terrible health such as asbestosis and mesothelioma.


Asbestos was used first 3,000 years ago by ancient civilizations that populated the area that is now the Finland. They used for plugging their houses and pottery. His popularity continued with the Greeks, Romans and Persians 2 000 years. They mainly used the substance in funeral rites or rags that often required, such as cleaning cloths or table napkins.


The popularity of asbestos decreased until the industrial revolution of the 19th century. With the rise of the machines has come the need for a material that was suitable for the heat, fire insulation and electricity that has been used or produced by machines. Asbestos has been recognized as an insulation is perfect for all of these things. In addition, it protects against chemicals and resistant to degradation. He has also as a silicate material, high resistance to traction and flexibility.


The arrival of the automobile industry and gain popularity in the industry of construction in the 20th century stimulated the production of asbestos loaded from 1900 until the 1980s. First, it was mainly used as brake pads, shoes and clutch car plates. However, when people began to move to the cities and businesses became skyscrapers, it is when the real revolution of the 20th century in the use of asbestos has begun.


In the 20th century, we began to be influenced and electricity. This translates into buildings, air conditioning, heating and wiring necessary to bring the electricity in the building. For example, to maintain our cold or hot air, we needed insulation in our walls and ceilings. In addition, the wiring to supply power was to be insulated to prevent sparks and catch things fire.


Thus, asbestos was soon an ingredient in many products, including:


Insulating walls
Tile
Ceiling tiles
Gypsum Board
Shingles
Counters
Pipes


Unfortunately, it was not until the 1970s that people began to protest against asbestos due to health related issues. Finally, in 1989, the U.S. Environmental Protection Agency issued the right of the asbestos ban and Phase Out regulated the use of asbestos in the industries. Also, the Occupational Safety and Health Administration issued laws controlling the amount that can be used in and around a work environment.


Even if we are now aware of the dangers of asbestos, millions of people have been exposed to material before it became regulated. For example, people still today could develop mesothelioma and other asbestos-related diseases.
