Abstract
In response to a confidential request from an employee, a health hazard evaluation was begun at Alcatel Telecommunications Cable (SIC- 3357), Roanoke, Virginia. The employee expressed concerns over potential exposures during the operation of the Chemical Vapor Deposition (CVD) process and when cleaning and cutting quartz glass tubes. A walk through tour was conducted to observe work practices and potential exposure risks, and to interview informally the employees on site. Personal breathing zone samples were also collected. Results from sampling found only trace amounts of airborne fused silica. The airborne silica collected was identified as mostly amorphous-fused-silica (60676860). The highest personal exposure was 0.217mg/m3. No crystalline silica was found. Optical examination of material taken from the saw waste receptacle found only amorphous-silica and aluminum-oxide (1344281). Very few of the workers had specific health complaints, but may voiced lingering concern about the potential for silica exposure. The author concludes that workers were not at risk from silica exposures during routine manufacture of optical fiber cable. During cleanup or maintenance work, there was a potential for exposure to fused silica. Recommendations were offered concerning local exhaust ventilation and the transport of CVD glass bubblers containing phosphorus-oxychloride (10025873).
