Abstract
A visit was made to the Centerless Grinding Company, Waltham, Massachusetts to determine the extent of exposure to N-nitroso compounds in the machine shop environment. The company had been in business for 24 years. It performed precision grinding on metals and plastics. The shop was equipped with nine Centerless grinders, one Blanchard grinder and two Hyprolap grinders. The company had nine employees; six of them were full time, while three were part time. When workers removed the materials being ground from the machine, their hands were in contact with the the grinding fluid, sometimes for a considerable period of time. No N- nitrosodiethanolamine (1116547) was present at a concentration above diluted. Air samples did not contain nitrosamines at or above the detection limit of 0.05 nanograms/liter. Since most synthetic grinding fluids have been found to contain high concentrations of nitrosamines, this facility may not be a typical machine shop in terms of the grinding fluids used.
