Whllo It would appear that tharo la no oauaa for concern aa to an undue lneldanea of canoar among those worlcara, any other oonolualon would be of doubtful validity until aore data are obtained. These data should consist oft 1. The documentation of the exposure in terns of duration and intensity (the latter will be very dlffloult to do for past years except in general terns). 2. A survey of the smoking habits of the exposed non. 3. A survey of a control group having the sane age and smoking characteristics as the exposed group but who do not work with asbestos fiber. 4. A ''blind'1 reading of the chest x-rays of the control and exposed groups. There ie sene interest at other plants in the possible health problems of those esiployees who work with asbestos end consideration should be given to enlarging the aeope of the study to laelude as many exposed persons as possible.
