In response to a request from the United Rubber Workers Local 745, a study was begun of possible chemical exposures in the curing department at the Kelly-Springfield Tire Company (SIC-3011), Freeport, Illinois. The concern was expressed that workers were exposed to nitrosamines and other chemicals released from presses in the curing departments. The facility operated around the clock with three shifts per day. The workers numbered 89 in the passenger tire curing area, and 67 in the rear farm tire curing area. About 21,000 tires were made per day in the passenger tire department and 1,750 tires in the farm tire department. Full shift personal breathing zone monitoring was conducted for N-nitrosamines, polycyclic aromatic hydrocarbons, and total particulates. No N-nitrosamines were detected in any sample. The benzene soluble fraction of airborne particles ranged from 0.20 to 0.78mg/m3. Total particulates were below the required limits. Eye, nose or throat irritation, headache and fatigue were reported by over half of the 25 randomly selected first shift employees. Approximately one third reported cough, and one fifth reported chest tightness, wheezing or shortness of breath. The available records did not reveal an unusual number of cancer deaths. The most frequent site was the trachea, bronchus or lung. The authors conclude that control of exposures to air contaminants may reduce the number of symptoms experienced by workers. The authors recommend the installation of local exhaust ventilation.
