Medical interviews and skin examinations were conducted, and the pH and total alkalinity of cutting and grinding fluids were evaluated on April 10 and 11, 1978, at the Brubaker Tool Company (SIC-3545) in Millersburg, Pennsylvania. The evaluations were in response to an employee representative request concerning skin rashes and irritation among workers in the wet grinding department. Thirty employees were considered to be affected. Skin irritation tests of the fluids were performed in the laboratory on 5 white albino rabbits. The dermatitis was attributed to the pH of cutting and grinding fluids (pH range 9 to 11), which were particularly irritating in neat concentrations, the presence of excessive particulate matter from tools and grinding wheels, the use of abrasive soap as a routine hand cleaner in washrooms, and contact with solvents in the thread grinding department. Potential hazards existed from possible benzene (71432) exposure, and from excessive noise in the thread department. For alleviation of the dermatitis hazard, the investigator recommends that barrier cream and waterless, non-abrasive hand cleaner be made generally available and be scrupulously utilized, fluids with less alkalinity be substituted for current ones, fluid concentrations be kept to minimum effective levels, fluids be frequently changed to remove abrasive waste particles, and workers be educated about factors which cause dermatitis.
