Investigation to Determine the Qualitative and Quantitative Extent of Health Records and Injury Claims Records to Hand Tool Vibrations in U.S. Industry.

Jefferson Medical College, Philadelphia, Pennsylvania, Final Report :38 pages
An investigation to determine whether qualitative and quantitative health records and injury claims records of workers exposed to hand tool vibrations in U.S. industry exist which would prove suitable records for an epidemiological study of segmental vibration induced disorders is reported. The search for records covered employers, unions, state workmen's compensation boards, and industrial insurance companies. Industries were selected in which workers were exposed to segmental vibration from: jack-leg drill (hard rock mining); jackhammer (pavement breaking); chainsaw (timber felling, and trimming); chipping hammer, sand rammer and grinder (foundry); discer and sander (automobile manufacture); and other pneumatic tools (ski and boot manufacture). It was determined that the paucity of suitable records did not imply that segmental vibration induced disease occurs infrequently. Evidence was found that Raynauds phenomenon of occupational origin was quite common in chainsaw operators and jack leg drillers; it was apparently less common among foundry workers. Other ill defined disorders of bones, joints, and soft tissues were common in one group of chipping hammer operators in a foundry. In general, on the basis of the records searched, it would appear that some basis for an epidemiological study is presently available; however, establishment of meaningful data bases on vibrational disorders would require computer and more sophisticated methods of recordkeeping than are currently in use.
