Title Evaluation of offset printing workplaces by workplace environment measurements and their problems
Original title Ofusetto insatsu sagyōba no sagyō kankyō sokutei kekka to mondai ten ni tsuite [in Japanese]
Bibliographic information 1 Mar. 1993, Vol.14, No.2, p.52-60. Illus. 9 ref.
Abstract Workplace measurements carried out in various printing establishments between 1980 and 1992 were reviewed. Whereas in the most recent evaluations 80% of the offset shops and 90% of the screen printing shops had acceptable ambient solvent concentrations (Control Class I), only 25% of the gravure operations were so classified. Replacement of chlorinated solvents by hydrocarbon solvents over the years has improved the quality of workplace air, but some workers have higher concentrations of organochlorine compounds in their urine than the atmospheric levels would suggest. This implies that they are exposed by skin absorption when cleaning the printing surfaces with solvent-soaked rags, and that there is a work-environment problem that is not revealed when the Control Classes of print shops are determined.
