NIOSH 1986 Jan:7 pages
Following a request from Local 440M of the Graphic Communication International Union, solvent exposures in the Toshiba Press area of Hirschfield Press (SIC-2751), Denver, Colorado were evaluated. Samples for petroleum naphtha (8030306), toluene (108883), and isopropanol (67630) were collected on organic vapor charcoal sampling tubes using vacuum pumps. Methanol (67561) was collected on silica gel tubes using vacuum pumps. All 12 workers were interviewed and 11 were monitored for exposure to airborne contaminants. The average concentration of petroleum naphtha was 53 milligrams per cubic meter (mg/m3) and ranged from 18mg/m3 to 106mg/m3. Toluene concentrations ranged from 0.01mg/m3 to 2mg/m3 for an average toluene concentration of 0.9mg/m3. The average isopropanol concentration was 17mg/m3 in a range from 3 to 33mg/m3. Methanol was found in only one sample at a concentration of the afterburner on the Toshiba Press was not working, although this occurred rarely. The author concludes that there is no health hazard in the vicinity of the Toshiba Press on the day of the survey. It is recommended that employees be informed about the chemicals they use to maintain and operate the press. Respiratory protection should be provided when the afterburner malfunctions.
