HHE Report No. HETA-85-335-1629, Lahey Printing Press And Office Building, Littleton, Colorado.
NIOSH 1985 Oct; :1-11
Environmental and breathing zone samples were analyzed for toluene (108883), perchloroethylene (127184), chloroform (67663), methylene- chloride (75092) and mineral spirits at the Lahey Printing Press and Office Building (SIC-2751, 6162, 8911), Littleton, Colorado in June, 1985. The evaluation was requested by the County District Health Department to assess solvent exposure in the building, a two story structure that housed the print shop on the first floor. Twelve office workers were interviewed. All individual solvent exposures were below their relevant standards. The ratio of concentration to threshold limit value for mixed solvent exposure ranged from 0.22 to 1.03. The American Conference of Governmental Industrial Hygienist criterion for mixed solvent exposure is 1.0. Five workers felt that exposures in the building affected their health and reported symptoms of headache, fatigue, drowsiness, or disorientation. These symptoms tended to worsen as the week wore on. All workers reported solvent odors when first entering the building. The authors conclude that a potential health hazard exists from solvent vapors on the top floor. Recommendations include improving the seal on the ventilation duct from the first floor, installing local exhausting ventilation in the print shop, and educating print shop employees on the current handling of solvents.
