Abstract
A Health Hazard Evaluation investigation was conducted by NIOSH on September 29-30, 1976, to determine whether materials used in the production of asphalt shingles and rolled roofing materials (SIC- 2952) are toxic in the concentrations found at the Certain-Teed Products Corporation plant, Richmond, California. The evaluation was prompted by a request from an authorized employee representative regarding the exposure of approximately 50 affected employees to various toxic dusts and fumes. Environmental surveys revealed that employees working in and around the coater line for roofing shingles were exposed to excessive concentration of limestone (1317653) and other nuisance dusts, while those employed in the slate operation were exposed to potentially toxic concentrations of a dust which contain crystalline silica (7631869). Exposure to benzo(a)pyrene (50328) other polynuclear aromatics, alpha-naphthylamine (134327), beta-naphthylamine (91598), aliphatic hydrocarbons, benzene (71432) and other aromatic hydrocarbons were not toxic. Exposure to asphalt fumes could not be adequately determined with the current sampling and analytical methods. There were only signs of irritation from exposure to dust and fumes among the 18 employees interviewed.
