Preliminary Control Technology Survey on Datel-Intersil Corporation, Mansfield, Massachusetts

摘要

A preliminary survey was conducted to assess control technology to reduce occupational exposure to lead (7439921) (Pb), silicon-dioxide (14808607) (Si02), and organic solvents at the Datel Intersil Corporation (SIC-3674), Mansfield, Massachusetts in December, 1983. Engineering controls in use at the facility included process isolation of the copper etching and photoresist operations, shielding, and local exhaust ventilation. Wet operations were used to control exposures to Si02. Personal protective equipment was used in all wet chemical operations. No monitoring systems were used in any of the assembly operations to evaluate exposures to chemical or physical agents. The author recommends that blood Pb concentrations be monitored. Trichloroethylene (79016) used in epoxy paint stripping operations should be replaced by the less toxic 1,1,1-trichloroethane (71556). Emergency power sources should be provided for the local exhaust ventilation systems for operations using toxic or flammable materials, and the airborne concentrations of combustible and toxic substances should be continuously monitored. Exhaust stacks should be reoriented to ensure that exhaust air is directed away from air intakes.
