History of asbestos.There are four main types of asbestos; Amosite (brown fibers), anthophyllite (gray fibers), white Christie, and blue crocidolite. Chrysotile has curly fibers while the other three have stem like fibers. These fibers fragment into dust very easily and float in the air. They can adhere to skin or clothing and are easily swallowed or inhaled. Half a century ago, asbestos was hailed by many as a miracle product. They said that almost everything can be done from this mineral. It is used as an additive for mortar and reinforce plastics. Asbestos fibers can also be separated into fine wires that do not drive electricity and are not affected by heat or chemicals. The use of asbestos considerably increased during the Second World War. Shipbuilding constituted asbestos largely in cargo ships and support vessels to isolate boilers, steam pipes and hot water pipes.
Asbestos became the miracle building material as it was easily obtained, processed and transported. After the Second World War cars used asbestos in shoes and clutch brake pads. Asbestos has found its way into residential and industrial materials construction, water supply, sewage materials, ceiling and floor tiles and vermiculite garden equipment to name a few products. In the 1970s, after the discovery of the health hazards of asbestos dust inhalation, the Consumer Product Safety Commission of the States prohibited the use of asbestos in several products that could release asbestos fibers in The environment during use. Regulations governing the use of asbestos and public concerns since 1970 have created a significant decline in the use of asbestos in the United States.
The same trend was observed in most developed world.In 1989 all new uses of asbestos were banned by the Environmental Protection Agency while former uses before that year were still allowed . The EPA suggested that schools inspect asbestos damaged and eliminate any exposure or lock it in protective barriers. Vermiculite, widely used in horticulture, has become a concern of the EPA. They recommended outdoor use, limiting the amount of dust used, and keeping wet of vermiculite. Health hazards Asbestos can create serious health risks such as coughing, lung injury, shortness of breath and lung cancer. Most people do not get sick in the early stages of contact but usually need continued exposure. This often means on jobs such as mining, grinding, asbestos manufacturing, and the construction industry. Firefighters, demolition and destruction of workers, drywall strippers, and any other person involved in the trades that involve the destruction of buildings, ships, and automobiles are also exposed to the dangers of asbestos. For a number of years, continuous exposure to asbestos can cause very serious health problems, such as mesothelioma.
Mesothelioma is a rare form of cancer of the membrane that lines many cavities in the body, including the lungs, abdomen and heart, and has been associated with exposure to asbestos dust. In mesothelioma, mesothelioma cells metastasize and damage adjacent organs and tissues. Mesothelioma can develop for a long period of time, often as long as twenty-five or thirty-five years before the symptoms appear Full Blown. Not all workers who have been exposed will develop diseases, but workers who have been exposed to the fibers that it can bring on their clothes, hair, shoes, and skin home to their families. To circumvent this risk, most industries, workers have to wash and change clothes before leaving work. Diet, Patient Advice Mesothelioma tractors and nutritionists may recommend a special cancer diet because many mesothelioma patients tend to lose their appetite because of worrying about their condition. Also, those who are undergoing treatment may choose not to eat because of the unpleasant side effects they may experience. Chemotherapy and some medications can cause a nutrient imbalance that needs to be corrected in order to keep the body as strong as possible
