Abstract
In response to a request from workers at the Timken Corporation (SIC- 3562), Canton, Ohio, an investigation was made of respiratory irritation, skin rashes, and headaches in machinists working in the roller bearing grinding area. Workers suspected the grinding fluid additive, Gulf-Agent-1688 as the cause. Grinding work involved 126 workers in two departments. Breathing zone and area air samples were collected in filters and analyzed by NIOSH Method P and CAM 283, bulk fluid samples were analyzed chromatographically, and colorimetry was used on air near a machine and in the Gulf-Agent- 1688 drum. Medical survey was made of grinding workers and workers in the adjacent inspection department. Total airborne particulate exposures were 1.6 to 2.6mg/m3 in grinding and 0.3mg/m3 in inspection, both below the OSHA limit of 5mg/m3 for mineral oil mist. Soluble-Oil-B (64742525) (64741964) and Gulf-Agent-1688 could not be successfully analyzed. No nitrosamines or ethylene-oxide (75218) were detected. Reported headaches and respiratory, eye, and other symptoms were not significantly different between 102 grinding workers and 52 inspection workers. The authors conclude that exposure to the machine oil mist is not the cause of reported symptoms, although work conditions have changed since Gulf-Agent- 1688 was introduced. Recommendations include substitution of the fluid, use of respirators and protective clothing or creams, personal cleanliness, and isolation of machines.
