Worker exposure to a coal antifreeze agent, Nalcoal-8894, was investigated at the Ellsworth Coal Preparation facility (SIC-1211), Eighty Four, Pennsylvania. The study was requested by the United Mine Workers of America and was performed on February 23, 1982. Air samples were collected for Stoddard-solvent (8052413), the primary constituent of Nalcoal-8894. Three employees per shift worked in a room where Nalcoal-8894 was used. A limited medical study was conducted for six workers. Very low concentrations of the solvent were in the area where Nalcoal-8894 was sprayed on the coal. The highest concentration was 64 milligrams per cubic meter, compared to a NIOSH recommended standard of 350 milligrams per cubic meter. Workers were required to spend a minimum amount of time in the area. Stoddard-solvent was not detected in the work area where the treated coal was loaded into rail cars. Two of six workers reported work related health symptoms including skin irritation, headaches, throat irritation, and acidic taste in the mouth. The authors conclude that no association could be found between reported symptoms and the use of Nalcoal-8894.
