Abstract A walk through survey was conducted at the Arlon Electronic Substrates Division (SIC-3079), Rancho Cucamonga, California in an effort to obtain information on the extent of exposure to 4,4'-methylenedianiline (101779) (MDA) during batch type mixing and during the manufacture and subsequent use of B-stage resin products, to measure the elimination of MDA in the urine of potentially exposed workers, and to identify deficiencies in the handling of MDA. At this facility electrical circuit boards were manufactured. MDA was an ingredient in the resin used to make preimpregnated fiberglass sheets. Personal air concentrations were below the proposed OSHA standard of 5 parts per billion. Widespread contamination of the work surface was noted on wipe sample analysis. Only two of the 52 urine samples taken contained detectable MDA. The author suggests that urine sampling may not be a reliable method for determining exposure levels in such an industry.
