In response to a request from the United Electrical, Radio and Machine Workers of America, Local 610, concerning employee exposure to resins, Shamrock Core Paste and dimethylethylamine (DMEA) a health hazard evaluation was conducted at Westinghouse Air Brake Company, Wilmerding, Pennsylvania. Workers had complained of headaches, respiratory and general symptoms, and dermatitis. DMEA was no longer being used at the time of the survey. An initial survey consisted of evaluation of personal and area air samples for triethylamine (121448) (TEA) and methylene-chloride (75092), and brief employee medical interviews. A followup survey conducted 5 months later again sampled air quality as well as conducting more thorough interviews with employees along with medical examinations and patch tests. Four of the 33 employees participating in the medical evaluation were found to have occupational dermatitis of the hands. Two workers had positive reactions to Isocure-I, one reacted to Isocure-II, and one reacted to Isocure-I, Isocure-II, and TEA. Three of these four positive workers also reacted to acetone (67641). These reactions were considered irritative rather than allergic. The workers were found to be ill informed about hazards associated with the materials they handled at work, did not use safety precautions, and poor sanitary conditions were noted in several personal work areas such as locker and rest rooms. Measured methylene- chloride and TEA levels were below recommended levels; however, TEA measurements sampling and analytical methods were still under development. The authors recommend that safety education, housekeeping, personal hygiene, ventilation, and worker protection measures be improved.
