Abstract
The International Brotherhood of Electrical Workers requested an evaluation of possible harmful occupational exposure to aluminum- silicate (1302767) ceramic fibers (CF) in a stress relief operation at Niagara Mohawk Power Corporation Unit-II, in Lycoming, New York. Stress relief operations were carried out by the Stone and Webster Engineering Corporation. Airborne fiber concentrations ranged from microns or less in diameter and fell mainly in the 0.5 to 2.0 micron range. The majority of the fibers were of respirable size. No cristobalite was found in any of the air samples. The identified fibers were mainly amorphous materials. Air and bulk samples contained primarily aluminum (7429905), silicon (7440213), and titanium (7440326). The identified fibers were alumino-silicate. In 1985, the electricians began using personal protective equipment when handling the insulating blankets. The authors conclude that there is insufficient data available regarding CF, but that it would be prudent to minimize exposures to the extent feasible. The authors recommend that the use of personal protective equipment be continued. Medical surveillance should be carried out on all workers exposed to ceramic fibers. Routine x-ray studies are not recommended.
