In response to a request from management and union representatives, a study was undertaken of eye irritation and odors during end capping operations, and the possible association between this operation and esophageal cancer at Nynex Enterprises (SIC-3661), in Syracuse, New York. This facility had a workforce of approximately 100 persons involved in telephone cable dereeling, cable cutting and end capping. Two retired workers had developed esophageal cancer. Measurements of air contaminants previously made by the company were all within acceptable limits with the exception of toluene- diisocyanate (584849) (TDI) which was recorded at 0.1 part per million in the highest sample taken. In monitoring conducted by NIOSH neither TDI nor toluene-diamine (25376458) was detected. Decomposition products from the bulk heat shrink materials included aldehydes, high molecular weight unsaturated aliphatics, some C6 to C13 alkenes, alcohols, and ketones. One current employee was identified with probable occupational dermatitis, which may have been related to frequent hand washing. Interviews with two retired workers with esophageal cancer indicated that one had not worked with heat shrink covers and the other had worked only briefly with these materials. The authors conclude that a further examination of the esophageal cancer incidence among NYNEX workers does not appear to be warranted. Some chemicals identified are upper respiratory irritants.
