In response to a request from management at SAS Circuits, Inc. (SIC- 3679), an evaluation was made of possible hazardous working conditions at the Littleton, Colorado site. Concern was voiced over the work conditions in the wet processing area, laboratory, lay up, deburring, silk screening, and plate cleaning departments during the production of printed circuit boards. Personal and area samples were collected and analyses performed for Freon-TF (76131), acetone (67641), methyl-isobutyl-ketone (108101), 1,1,1-trichloroethane (71556), and butyl-cellosolve (111762); results indicated no hazardous levels existed. Additional breathing zone and area samples were collected for chromium (7440473), copper (7440508), nickel (7440020), and lead (7439921). Copper alone was detected, ranging from 0.001 to 0.23mg/m3. No cyanide was detected in air samples. The author concludes that a hazard did not exist at the time of the survey. The author recommends that employees be educated regarding the toxicology of all chemicals they deal with, that eye wash stations be installed in the plating and etching departments, that the large water hose in the plating department be replaced with several shorter hoses that can be better stored when not in use, that a storage area be designed for all acids and other chemicals used in the plating processes, and that a chemical hood with exhaust fans be installed in the laboratory.
