Health Hazard Evaluation Determination Report No. 77-88-457, Galion Amco, Inc., Galion, Ohio

摘要

The National Institute for Occupational Safety and Health (NIOSH), received such a request from the plant manager of Galion Amco in Galion regarding an on-site toxicity evaluation of the screw machine shop operations which included the use of presses, plating machines, vapor degreasers, cutting oils and water soluble cleaners. An initial environmental survey was conducted at Galion Amco on July 22, 1977. Air samples were obtained in workers' breathing and in selected areas of potential maximum concentration. Oil mist samples were collected for the straight oils on filters at a flow rate of 1.5 liters per minute. The samples were analyzed for particulate oil mist using a non-dispersive infrared oil analyzer. Samples for the synthetic oils were collected on AA filters at 1.5 1pm. The bulk samples for these oils were extracted with carbon tetrachloride and standards were prepared from the extracted oils. The filter samples were extracted oils. The filter samples were extracted in a similar manner using carbon tetrachloride and the standards and samples were scanned over a spectral range of 3400-2700 cm-1.
