Survey for N-nitroso Compounds at White and Bagley Company, Worcester, Massachusetts.
NIOSH 1977 Dec:8 pages
A hazard evaluation and technical assistance survey of White and Bagley Company, Worcester, Massachusetts, to determine the extent of exposure to N-nitroso compounds of employees involved in the manufacture of cutting fluids and lubricants (SIC-2992) is reported. Bulk air samples were taken from separate areas in the manufacturing process. N-nitrosodiethanolamine (55185) (NDEIA) was detected in concentrations from 20 to 500ppm in all samples except one. An unidentified nonpolar triethanolamine (121448) (TEA) responding material was also observed. The presence of NDEIA represents a potential hazard through dermal contact or inhalation. The occurrence of NDEIA in the sampled TEA storage tank was considered an obvious source of contamination. However, a sample of grinding concentrate contained 7 times as much NDEIA as would come from the TEA used alone, and the packaged product contained almost 90 times the level of NDEIA expected if TEA were the only source of contamination.
