ANSWERS TO QUESTIONS ASKED BY INSULATORS
1. What are early symptom of asbestos is?
Asbsstosis is caused by ths inhalation of small particles of asbestos. There is apparently some chemical reaction within the lungs to the asbestoa 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 cosmon kinds of asbestos available one kind is much more toxic than the other two and we do not usa the more toxic kind. The size of the fibers inhaled have a definite bearing on how much la inhaled and how far into the lunga 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 common symptom experienced by those people that have been diagnosed as having asbestosis 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. Ths second most consnon symptom is a dry hacking cough. Other symptoms do occur whan the disease is more advanced. 2. Can asbestosis be cured, and how?
When asbestoeie has developed enough to be recognized I do not believe it ia curable. By thia I mean that I do not believe the aebeatoa can be removed from the lunga; however, we would certainly
not allow any further exposure to aebeatoa or any other type of
pulmonary irritant. Thia again polnta to why we are continually monitoring tbs conditions under which we work end the preventive measures that we have insisted upon such aa good ventillatlon end masks. In this Instance prevention is tha only cure that is of any great value.
