Worker exposure to dust during tearoff operations of old coal-tar pitch and petroleum pitch roofs was investigated. The survey resulted from a request by the United Union of Roofers, Waterproofers and Allied Workers and was performed on November 2, 1981 at McAlpin's Department Store, Cherry Grove Shopping Center (SIC-1761), Cincinnati, Ohio. About 10 workers were involved in the roof removal. Personal breathing zone total dust samples and a bulk dust sample were collected and analyzed. The bulk dust contained bulk material. No polynuclear-aromatic-hydrocarbons (PNAs) were detected in the bulk samples. In the personal breathing zone, the cyclohexane soluble fraction ranged from 0.09 to 2.3 milligrams per cubic meter. Store employees reported no work related health complaints. No recommended exposure value has been established for cyclohexane solubles associated with petroleum pitch. The author concludes that workers were not exposed to PNAs during the petroleum pitch roof tearoff. The authors suggest that exposure to petroleum pitch dust be kept as low as possible until more information is available on possible health effects resulting from exposure.
