In response to a request from a representative of the East Leyden High School (SIC-8211) located in Franklin Park, Illinois, an evaluation was made of possible hazardous conditions in the art department of the school. Particular attention was given to the use of various substances during ceramics, metal casting, and other special class activities. The art department was located in the basement of the school; the rooms were supplied with general ventilation through the central heating and cooling system of the school. Local exhaust ventilation is also provided at individual machines and in the kiln room. The 8 hour time weighted average concentration of respirable crystalline silica (7631869) as quartz (14808607) was 42 micrograms/cubic meter (microg/m3) in the personal breathing zone air sample and 69microg/m3 in the area air sample. The respirable particulate concentration was 2.8 milligrams per cubic meter (mg/m3) in personal samples and 2.4mg/m3 in area samples. The quartz content of a bulk clay sample was 19 percent. During bisque firing, the total particulate concentration in the area air sample was 0.1mg/m3. Concentrations of carbon-monoxide, sulfur-dioxide, nitrogen-dioxide, hydrochloric-acid or trace metals during ceramic firing were not significant. Analysis of a bulk sample of the lining of the kiln indicated no asbestos was present. The author concludes that no health hazard existed at the school; a potential hazard may exist if exposures are not properly controlled. The author recommends specific changes in procedures to reduced exposures from art processes.
