Alternative Equipment for Bulk Degreasing and Abrasive Blasting Operations: Beloit Fiber Systems. 1995

  TURI Technical Report No. 22. The purpose of this project is to improve worker health and reduce the use of toxic chemicals used in the re-manufacturing or refurbishment of used papermill machinery. The specific toxics use reduction techniques evaluated were production unit redesign, production unit modernization, and in-process recycling. In order to reduce our operating costs and lessen our environmental impact, the Beloit Fiber Systems division attempted to decrease the time involved in the cleaning of customer furnished parts for their new rebuild operation center. This report summarizes the efforts of our in house personnel to reduce and subsequently eliminate the use of 1, 1, 1-trichloroethane in the cleaning of parts subsequent to inspection and prior to painting. To accomplish this, we investigated combining the initial stages of part examination, cleaning and blasting, into one process with a concept of making it automatic. Download PDF file (5.92 MB)

Health and Safety Impacts of Citrus-based Terpenes in Printed Circuit Board Cleaning. 1993.

  TURI Technical Report No. 6. This report examines the health and safety impacts of d- Limonene as used in the printed circuit board cleaning operation. It focuses on animal and human toxicological studies and equipment safety features to conclude the impacts to the people involved in the printed circuit board cleaning operation. Data was obtained through data base searches and from manufacturers of d-Limonene, printed circuit board (PCB) defluxer manufacturers and PCB cleaning equipment manufacturers.
