Description:A study was conducted at the Herbert Malarkey Roofing Co. (SIC-2952) to determine whether materials present in the production of asphalt (8052424) shingles and rolled roofing materials are toxic as used or found. Materials involved in fabrication of these products are felt, asphalt (petroleum), colored granules, limestone (1317653), talc (8030840), and mica (12001262). Medical evaluation was conducted by use of a medical questionnaire at the beginning and end of a day's shift. Questions concerned the employees' perception of irritated eyes, nose and throat or skin itching. Environmental sampling was designed to include all job descriptions in either breathing zone or general area samples. The data reveal that in certain work areas there were concentrations of total dust and free silica (7631869) in excess of evaluation criteria based on breathing zone concentrations. The saturator man's exposure to asphalt fumes at most times is not considered to be toxic. Excessive concentrations of total dust and asphalt fumes were present in the area above the coater. Employees' exposure to benzo(a)pyrene (50328), other polynuclear-aromatic-hydrocarbons, beta-naphthylamine (91598), aliphatic and aromatic-hydrocarbons were not toxic at concentrations found. There were no indications of eye, nose, throat or skin irritations. [Description provided by NIOSH]
