KLDICAL EEPARTKEJfT : ' ,// *; t>V CEAXSERS VORES _. / ASEESTQS I an enclosing the data we hare extracted fro* the medical records of 52 pipe ccnrereri at Chaabers Work*. Vhile It would appear that there is no cause for concern as to an undue incidence of cancer among these workers, any other conclusion would be of doubtful validity until more data are obtained. These data should consist oft 1. The documentation of the exposure in terns f duration and intensity (the latter will be very difficult to do for past years except in general terms). 2. A surrey of the sacking habits of the exposed men. 5. A surrey of a control group haring the same age and aaoking characteristics as the exposed group but who do not work with asbestos fiber. A. A "blind" reading of the chest a-rayi of the control and exposed groups* There is sooe interest at other plants in the possible . health problems of those employees who work with asbestos and consideration should be given to enlarging the soope of the study to include ax many exposed persons as possible. This is a cituation in which the union is well informed and is playing a lending role in gathering health information on its members. Management must obviously be at least as well informed as to any hazards to health that stay be associated with asbestos. WLUAX 2.
