Asbestos Safety in the Prevention of Mesothelioma

WHAT IS MESOTHELIOMA?

Mesothelioma is a rare form of cancer of the lungs which may be caused by exposure to asbestos. The major risk factor for mesothelioma is working with asbestos. About 70 percent to 80 percent of all mesothelioma cases report a history of asbestos exposure at work. Some individuals without any known exposure to asbestos have been diagnosed with mesothelioma. There is a great number of workers who have been exposed to asbestos, have contracted mesothelioma, and have sued their employers. Currently lawyers advertising mesothelioma litigation are all over the place. Asbestos use has been outlawed in many countries, and strict safety precautions are enacted to prevent exposure to asbestos and the resulting mesothelioma. In other parts of the world asbestos safety is much less regulated. I remember being in Taiwan about ten years ago and asbestos roofing was commonplace. Mesothelioma is the one cancer that can be directly associated with asbestos.

As bad as asbestos has been made out to be it is a valuable mineral with a rich history. In manufacturing, the use of asbestos was originally believed to be a miracle mineral it is cheap to produce, has a high resistance to heat, chemical and electrical damage, and tensile strength. Over time it became obvious that workers in asbestos factories and mines who inhale asbestos fibers regularly, over a long period of time are at high risk for contracting the disease.

Asbestos is in great demand in many countries as a cheap, easy to use and durable construction material, and there is therefore a wide market for it. Many people are still unaware of the health risk involved with asbestos and do not know what mesothelioma is. As older buildings are demolished, the remaining asbestos is snatched up and sold.

MESOTHELIOMA SYMPTOMS

Symptoms of mesothelioma include shortness of breath, chest wall pain, and weight loss, and diagnosis can be checked using a CT scan or chest X-ray, and can be confirmed with a biopsy. Asbestosis is another disease caused by exposure to asbestos. While not cancerous, it is caused by scarring of the lung tissue which causes the lungs to lose their ability to transfer oxygen to the blood. Asbestosis is difficult to diagnose unless x-rays are taken periodically and compared to detect changes is the condition of the lungs. Mesothelioma is often difficult to pinpoint the cause or origin of the disease because it has a latency period of about 40 years.

SAFETY

Lawsuits against asbestos manufacturers have been appearing since 1929. Since then, the liability from such court cases has reached billions of dollars for not meeting the general duty clause even after the links between prolonged asbestos exposure and Mesothelioma have been confirmed. Certain industries have higher incidence rates of asbestosis and mesothelioma. Among the highest is the shipbuilding industry. Workers would often spend over 8 hours a day in an enclosed ship inhaling asbestos fibers without any respiratory protection. Because of the lawsuits and the general recognition that asbestos has inherent dangers, the US EPA has rigorous policies regarding all aspects of asbestos safety. The evidence is that when handled safely, the use of it can be properly managed. It is often more safe to leave asbestos in place but to ensure that people are notified of its presence and safely work with it.

SYNERGISM AND SMOKING CIGARETTES

There is a synergistic effect between smoking cigarettes and exposure to asbestos. This means that someone who smokes and has been exposed to asbestos is at a greater risk of developing lung cancer than the risks of someone who only smokes or the risks of someone who is only exposed to asbestos combined.
