Abstract
A request was received from the International Chemical Workers Union to investigate respiratory symptoms occurring from possible exposure to silica (7631869) dust along with neurologic symptoms of memory loss and disorientation from possible exposure to aluminum-oxide (1344281) dust at the Sancap Abrasives Inc. (SIC-3291) facility in Alliance, Ohio. Sancap Abrasives manufactured coated abrasives (sand paper), and had previously discontinued use of abrasives containing silica. The survey found 8 hour time weighted average (TWA) exposures of respirable particulate concentrations for 20 samples ranging from 0.09 to 0.79mg/m3. Total particulate concentrations ranged from 0.29 to 4.58mg/m3. Results of 20 personal air samples for aluminum (7429905) concentrations ranged from less than detectable to 0.02mg/m3. The amounts of free silica in all personal air samples were below the limit of detection. The amounts of quartz (14808607) and cristobalite (14464461) in two bulk samples of aluminum-oxide were also below the detection limits. No neurotoxic agents were identified at the facility. The authors conclude that silica exposures were not sufficient to pose a serious risk of silicosis. Annual medical examinations were recommended for all workers working in the coated abrasives division for a total of at least 10 years when silica was used.
