Abstract
In response to a request from the International Chemical Workers Union, an evaluation was made of possible hazardous exposures to workers in the Metal Coated Fibers (MCF) department of American Cyanamid (SIC-3471), Wallingford, Connecticut. A walk through evaluation was made of the MCF where 24 employees worked to unwind graphite fibers as a continuous strand through plating tanks, plate nickel onto the fiber, dry it and rewind it. A second operation involved the use of epoxy resins on the nickel coated fiber and then cutting the fiber into various sizes. Air quality monitoring revealed the following concentrations: methyl-chloroform (71556), 7.7 to 48.15mg/m3; methylene-chloride (75092), 13.9 to 74.7mg/m3; nickel (7440020), 7.3 to 51.2 micrograms/m3; and synthetic graphite (7782425), 0.00003 to 0.23mg/m3. Respirators were used in portions of the operation so that these amounts do not necessarily reflect employee exposure levels. Medical examinations revealed seven of 56 workers had a work related rash. Only two employees had a positive patch test to nickel. The authors conclude that excessive exposure to nickel and potential exposure to methylene-chloride existed in the MCF department. Irritant dermatitis was apparently associated with exposures on the sizing line. The authors recommend measures to be taken to reduced exposures to nickel and other chemicals.
