Abstract
In response to a request from United Auto Workers Local 647, an investigation of possible hazardous working conditions was begun at the General Electric Corporation (SIC-3724) located in Evendale, Ohio. Concern was expressed over two operations: the removal of Viton and the grinding, milling, and cutting of PMR-15 during the production of aircraft engine parts. No residual 4,4'- methylenedianiline (101779) (MDA) was detected from an analysis of a bulk sample of graphite composite particulate. Seven personal breathing zone and general area air samples were analyzed and shown to contain no airborne fibers. Concentrations of total and/or respirable particulate in the Development Manufacturing Operations (DMO) area were very low, ranging from 0.01 to 0.06mg/m3 for respirable particulate and from 0.07 to 0.17mg/m3 for total particulate. Most employees reported to have skin problems in the DMO area had histories consistent with possible work related skin disorders with pruritis and redness of the skin. In one case the children of a worker also had experienced rashes. Although some workers found that wearing gloves, sleeves, and paper overalls decreased the frequency of the skin disorders, other workers considered them to be a safety hazard. The authors conclude that a potential hazard existed to the exposed, unprotected skin from graphite composite particulate. The authors recommend that changes be made in the type of protective clothing used. Local exhaust ventilation should be used when machining composite components without cutting fluids.
