A walk through survey was made of the Martin Marietta Missile and Electronics Group, Orlando, Florida to evaluate worker exposures, protective equipment, and engineering controls used to reduce employee exposures to 2-methoxyethanol (109864) (2-ME), 2- methoxyethyl-acetate (110496) (2-MEA), 2-ethoxyethanol (110805) (2- EE), and 2-ethoxyethyl-acetate (111159) (2-EEA). The facility was involved in the design, development, and production of missile and electro optical systems used for aircraft and naval combat weapons programs. Of 38 field samples collected for each of the four target ethylene glycol ethers, only nine samples indicated the presence of any of the compounds and one sample indicated more than one to be present. In 32 long term samples taken, only 2-MEA was detected and only in one area of the facility. The exposures in the Patriot area resulted from the repetitive application of a primer material by hand to a piece of propulsion harness assembly. The potential for exposures resulted from accidental spills of the liquid primer in this area. Some skin protection was afforded by gloves, but the workers wore only ordinary street clothes and no respirators. Peak exposures to 2-EEA in the Hellfire area occurred during the spray painting of missiles. The authors recommend that local exhaust ventilation be installed at work stations in the Patriot area and that impermeable coveralls be given to workers in the Hellfire and Patriot areas.
