Environmental and personal air samples were analyzed for methylene- chloride (75092), 2-butanone (78933), toluene (108883), and xylene (1330207) at a roof installation work site in Baltimore, Maryland, on September 23 to 25, 1981. A representative of the United Union of Roofers, Waterproofers, and Allied Workers, in Baltimore, Maryland, requested the evaluation. Exposures to airborne vapors of methylene-chloride ranged from none to 31.1 milligrams per cubic meter (mg/Cum), compared with the OSHA standard of 1750 mg/Cum. 2- Butanone concentrations ranged from none detected to 17.6 mg/Cum, compared with the OSHA standard of 590 mg/Cum. Toluene concentrations were in the range of 2.8 to 16.6 mg/Cum, below the OSHA standard of 750 mg/Cum. Xylene concentrations were also below the OSHA standard of 435 mg/Cum, ranging from none to 1.3 mg/Cum. The author concludes that a health hazard from solvent vapors did not exist at this construction site. He recommends that workers try to maintain an upwind attitude when applying roofing adhesive, or heat sealing edges of the roofing sheets, avoiding skin contact with the adhesives, use of respirators when working in confined spaces, and worker education.
