What arc early symptoms of asbestoais? Asbestos is is caused by the inhalation of small particles of asbestos. There is apparently some chemical reaction within the lungs to the asbestos as well as an irritating effect by the fibers of asbestos. There are several factors in the development of this disease that should be noted. Of the three coasson kinds of asbestos available ora kind is much more toxic than the other two and we do not use the more toxic kind. The size of the fibers inhaled have a definite bearing on how much is inhaled and how far into the lungs these can be breathed. The amount of asbestos in the air obviously affects how much is inhaled; further, the number of hours of ex posure per day will influence how much is inhaled. Another factor we do not have any measurement of is the resistance of any individual that might be exposed. The most cofliaon symptom experienced by those people that have been diagnosed as having asbestoais is shortness of breath on exertion. Obviously, this is also a symptom of many other diseases which Include not only pulmonary or chest conditions but any systemic illness and especially circulatory illnesses. The second most common symptom is a dry hacking cough. Other symptoms do occur when the diaeeae ia more advanced. 2. Can aabeatoais be cured, and how? When asbestoais has developed enough to be recognized I do not believe it ia curable. By this I-mean that I do not believe the asbestos can be removed from the lungs; however, we would certainly not allow any further exposure to asbestos or any other type of pulmonary Irritant. This again points to why we are continually onitoring the conditions under which we work and the preventive measures that we have Insisted upon such as good ventillation and masks. Za this instance prevention is the only cure that is of any greet value. DUP 0901246 ANSWERS TO QUESTIONS ASKED BY INSULATORS Pag* 2 3. Can Inaulatora have more frequent respiratory examinations?
