Health hazard evaluation report: HETA-85-251-1620, TRW Electronics, Inc., Colorado Springs, Colorado.

Environmental and breathing zone samples were analyzed for organic solvents, lead (7439921), zinc (7440666), and toluene-2,4- diisocyanate (584849) at TRW Electronics, Incorporated (SIC-3674), Colorado Springs, Colorado in April, 1985. The evaluation was requested by the company management to determine if there were health hazards that had been overlooked by the company medical and industrial hygiene staff. Work practices were observed. An unspecified number of employees were interviewed. 2-Ethoxyethanol (110805) was detected in breathing zone samples, average concentration 6.2 milligrams per cubic meter (mg/m3). The OSHA standard for 2-ethoxyethanol is 740mg/m3, while NIOSH recommends reducing exposure to the lowest feasible limit. All other exposures were either below the limit of detection or their relevant standards. Solvents and paints were stored in unacceptable places and posed fire and health hazards. The only consistent employee health complaints were narcosis, burning eyes and dermatitis, typical complaints observed when working with solvents. The author concludes that a health hazard due to overexposure to 2- ethoxyethanol exists at the facility. He recommends conducting an industrial hygiene survey every 6 months, storing flammable solvents and paints in appropriate storage cabinets, and educating the workers about the hazards of the chemicals.
