HHE Report No. HETA-83-380-1671, Roofing Sites, Dayton, Ohio.
NIOSH 1986 Feb:9 pages
Tear off and application operations at roofing sites (SIC-1761) in the Dayton, Ohio area were evaluated in August and September, 1983. The evaluation was requested by the United Union of Roofers, Waterproofers and Allied Workers to investigate potential worker exposures to coal tar products, asphalt (8052424) and solvents. Personal breathing zone air samples were collected for determination of total particulates, benzene solubles and polynuclear aromatic hydrocarbons (PNAs). Single ply system adhesive bulk samples were analyzed by gas chromatography/mass spectrometry. Personal breathing zone air samples were examined for adhesive components. Total particulate concentrations during tear off operations ranged from 0.76 milligrams per cubic meter (mg/m3) to 2.84mg/m3. During tear off, exposures to benzene solubles ranged from undetectable to tear off and or petroleum pitch application. In personal breathing zone samples concentrations of the major adhesive solvents were: xylene (1330207), undetectable to 5.3mg/m3; toluene (108883), 6.0 to 96mg/m3; acetone (67641), undetectable; ethyl-benzene (100414), undetectable to 1.3mg/m3; hexane (110543), 3.5 to 72mg/m3; and other hydrocarbons, undetectable to 0.59mg/m3. The author concludes that workers are not exposed to PNAs nor overexposed to solvent vapors during roofing work. Wetting the roof during tear off, use of protective eyewear, and avoiding skin contact with solvents are recommended.
