HHE Report No. MHETA-87-039-1837, Old Ben Coal Company, Benton, Illinois.
NIOSH 1987 Jun:10 pages
In response to a request from the Deputy Administrator, Occupational Health, of the United Mine Workers of America, a study was made of possible worker exposure to two hydraulic fluids at the Old Ben Coal Company (SIC-1111) located in Benton, Illinois. Employees using Solcenic-3A hydraulic fluid or working near its area of use had reported eye, skin, or respiratory irritation. Solcenic-2 fluid produced no symptoms. Chemical analysis revealed that Solcenic-3A contained dipropylene-glycol isomers and a small amount of ethanolamine (141435) which were not present in Solcenic-2. The authors suggest that these components may lower the Solcenic-3A odor threshold. Area air evaluations indicated no harmful exposures to the component methyl-isobutyl-carbinol (108112), with exposures of 1.4 and 3.4mg/m3 determined for two of 11 samples (American Conference of Governmental Industrial Hygienists threshold limit value, 100mg/m3). No excessive exposure to the component napthenic- mineral-oil was found; it was considered that workers were exposed to it only during hydraulic line ruptures or fluid spills. Of 13 workers reporting symptoms, nine of 11 interviewed had symptoms possibly due to skin or inhalation exposure to Solcenic-3A. The authors suggest that inhalation symptoms are a reaction to its strong vapor. They conclude that there is no health hazard, but they recommend use of protective equipment, proper disposal of waste, and use of nonirritating Solcenic-2.
