Industrial Hygiene Walk-Through Survey Report on Screen Printing Exposure at ACRO Screen, Anaheim, California, Report No. IWS-77-32.
NIOSH 1979 Apr:4 pages
An industrial hygiene walk through survey was conducted by NIOSH at ACRO Screen in Anaheim, California, in 1979 to characterize and evaluate chemical exposure of workers in the screen printing industry and to present industry wide recommendations. The surveyed facility was located in a 16,000 to 17,000 square foot building with natural ventilation and good lighting. The workforce included ten to 14 production workers. There were six to seven printers and helpers, two artists, one screen maker, and four to five administrative and clerical or sales workers. Solvents used in the screen printing process included mineral spirits and a naptha lacquer thinner containing isopropyl-alcohol (67630) and methyl- ethyl-ketone (78933). Nitrogen cylinders, paints, and solvents were stored outside the production facility. A hot biodegradable cleaning solution in a bath tank was used to remove all types of ink from the screen; the remaining ink was removed with a high pressure water stream in an enclosed drained trough. No formal industrial hygiene or safety programs were in effect. Solvent vapors generally appeared low and housekeeping was good. There was one case of allergic contact dermatitis in a worker using ultraviolet cured ink. Wearing of gloves and long sleeves were used for prevention. Recommendations included evaluation of ventilation to provide appropriate air exchange; sampling of air near the carbon arc lamps for ozone and oxides of nitrogen, with installation of local exhaust ventilation if necessary; provision of screening around lamps; determination of methyl-methacrylate (80626) monomer emissions; and grounding of solvent containers.
