Health Hazard Evaluation Report, HETA 2007-0201-3086, Sanmina-SCI (Trade Name) Corporation, Huntsville, Alabama, August 2009. Evaluation of Health Concerns at a Printed Circuit Board Manufacturing Plant

摘要

NIOSH received a confidential employee request for an HHE at Sanmina-SCI (TradeName) Corporation (Sanmina-SCI) located in Huntsville, Alabama. Employees were concerned about exposure to solder paste and fumes during the fabrication, assembly, and testing of printed circuit boards, and noise. Other exposure concerns included copy machine toner, asbestos, mold, and dust. Health effects mentioned in the HHE request included cough, burning eyes, nosebleeds, loss of voice, headache, sinus infection, bronchitis, and respiratory problems. On July 9-10, 2007, we conducted our first site visit. We toured the facility to observe work processes and practices, conducted confidential medical interviews with 40 employees, and collected GA air samples for VOCs and surface wipe samples for lead and tin. We reviewed air sampling records, injury and illness records, the respiratory protection program, and MSDSs. We also reviewed the PPE used for the solder dross cleaning operation and the maintenance schedule for the ARUs. We conducted a second site visit on December 12-13, 2007. We collected air samples for lead and specific VOCs. We conducted noise dosimetry at the AI stations, evaluated the room acoustics near ARUs, evaluated the effectiveness of local exhaust hoods for the wave solder and surface mount machines, and collected hand wipe samples to assess lead contamination on skin.
