Bock Ethyl Corporation Post Office Box No. 341 Baton Rouge, Louisiana 70821 Dear Roy:- Our congratulations to Dr. Robinson for his alertness in gathering a series of insulator x-rays in one place for study by an expert in roentgenographic changes of asbestosis. The finding of one definite and one equivocal case of asbestosis in Baton Rouge indicates the need for further study. As an approach to the problem we suggest:- 1) Re-X-ray the equivocal case 2) Current chest X-ray on all asbestos-handling employees 3) Industrial hygiene survey of the asbestos-handling operation 4) Annual follow-up X-ray on all exposed personnel 5) Annual ventilatory function studies on all exposed personnel 6) Pre-placement selection for new insulator personnel to exclude employees with significant pre-existing pulmonary disease 7) Restriction of definite cases of asbestosis .from further exposure to asbestos We have suggested to Dr. Burdick that he have his chest X-rays on asbestos-exposed employees reviewed as an addendum to an industrial hygiene survey to take place in Houston in mid-July. If you would like to discuss this problem, please let us hear from you. ' Very truly yours. RTG/af cc: Dr. George Roush, Jr. Richard T.
