Health hazard evaluation report: HETA 98-0347-2758, Lockheed Martin Aeronautical Systems, Marietta, Georgia.
In September 1998, the National Institute for Occupational Safety and Health (NIOSH) received a health hazard evaluation (HEE) request from Lockheed Martin Aeronautical Systems (LMAS) in Marietta, Georgia. The joint management and employee request concerned potential office employee exposures to diisocyanate-containing paints, primers, solvents, and cured and uncured composite materials used during the manufacturing of the F-22 fighter jet. The request stated that office workers in Area K of Building 11 had experienced breathing difficulties, asthma, burning eyes, and neurological and memory impairment. In response to the request, NIOSH investigators conducted an initial site visit at LMAS on October 30, 1998, and returned to conduct medical interviews and a tracer gas ventilation study on February 17-18, 1999.
