In some cases, new x-rays may be required. The objective of this program is to determine if there are any lung abnormalities that may be related to asbestos exposure. Other employees' x-rays will continue to be reviewed at the time of their regular physical examination. The program is expected to be completed by March 31, 1931. As is our policy, employees will be informed immediately of any abnormality observed. Physicians and radiologists traditionally have not specifi cally examined x-rays for minute, early signs of thickening of the lung lining (pleural thickening). Based on developments in and outside the Company during the past decade, medical knowledge and understanding of asbestos-related lung abnormalities have increased dramatically, making early identification of these abnormalities more feasible. Therefore, the current review program is being conducted in the light of this increased knowledge and understanding to identify and follow up on any abnormalities which may have been undetected under traditional methods. The Medical Division began this year a program to better train Company physicians in early detection procedures. That training is now largely completed, and the physicians have begun their review program in conjunction with our consulting radiologists. Du Font believes that it is the first company in the chemical industry to initiate such an extensive program. It should be strongly stressed that an early positive reading on an x-ray does not necessarily mean that an employee has, or will develop, asbestosis. No medical treatment is required for asbestosrelated abnormalities where no disease is present but all workrelated cases will be referred to a pulmonary specialist at Company expense for evaluation and consultation. * We'believe that our procadure for handling asbastos insula tion has ensured a leval of exposure wall within acceptable limits. Therefore, no changes in handling procedures are anticipated. Any cases of asbestos-related abnormalities detected now would be the result of exposure many years ago, at Du Pont or in previous employment, at a time when low levels of exposure to asbestos vfn not known to bo potentially harmful.
