A walk through survey was conducted at the General Electric Company (SIC-3079), located in Albuquerque, New Mexico, to obtain information on the extent of exposure to 4,4'-methylenedianiline (101779) (MDA) during hand layup work with preimpregnated graphite fabric while making molded jet engine parts, to obtain information on the elimination of MDA in the urine of potentially exposed workers, and to identify deficiencies in the handling of MDA and to offer recommendations for improving worker protection. A total of 210 worker urine samples was taken. Other samples taken included air samples, samples of glove washings, surface wipe samples, shoe samples, and bulk samples. From the data obtained it was possible to estimate the primary sources of exposure and their relative importance. Comparing the mass of airborne MDA inhaled with the amounts measured in the urine the following day suggested that skin contact was a significant contributory route of exposure. The author states that further efforts should therefore be made to reduce this exposure. Such efforts would include the selection of better personal protective equipment and improved work practices. Possible engineering modifications would be limited due to the manual nature of the work involved.
