In response to a request from the American Flint Glass Workers Union Local 146, an investigation was made into possible hazardous working conditions at Ross Mould Inc. (SIC-3544), Washington, Pennsylvania. Employees were reportedly experiencing numbness in their fingertips from the use of the power equipment. The company manufactured molds used in the production of glass containers. At this site, castings made of iron or bronze are machined into molds and then ground polished, and deburred using power hand tools. Videotapes were made of the work activities and interviews were held with the workers. Measurements were made while 21 tools were used by nine employees. The mean hand/arm vibration (HAV) experienced by the workers was 28 meters per second squared (m/sec2) expressed as 4 hour equivalent exposures. Mean HAV ranged from 18 to 40m/sec2 for the three different job titles that were evaluated. The limit recommended by the American Conference of Governmental Industrial Hygienists was 12m/sec2. The authors conclude that a potential health hazard existed from overexposure to hand/arm vibration. The authors recommend that a medical monitoring program be instituted, and measures should be taken to reduce exposure to vibration.
