National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Industrial Hygiene Survey Report of TRW Electronic Products Inc., Colorado Springs, Colorado,

PB89186647

Publication Date	1989
Personal Author	Piacitelli, G.; Krishnan, R.
Page Count	26
Abstract	As part of a larger study of the effects on workers of exposure to ethylene glycol ethers, a visit was made to TRW Electronic Products Inc. (SIC-3679), Colorado Springs, Colorado. Work at the site included coating/marking, bonding, soldering, degreasing and surface mount assembly of printed circuit boards. The use of 2-ethoxyethyl-acetate (111159) was noted in the blending of the multiple components of a coating mixture and in the application of the coating mixture to printed circuit board parts. However, the only process operation which involved any potential exposure to ethylene glycol ethers was the touch up marking of circuit boards. No detectable concentrations were noted during sampling due to the very limited use of the glycol ether containing materials, effective work practices, and adequate engineering controls. Due to the fact that the exposures to 2-EEA were not detectable, and to the small number of potentially exposed workers at the site, the authors recommend that the company not be included in further indepth studies.
