Title The development of substitute inks and controls for reducing workplace concentrations of organic solvent vapors in a vinyl shower curtain printing plant
Bibliographic information Aug. 2003, Vol.18, No.8, p.597-619. Illus. 16 ref.
Abstract In order to comply with US regulations with respect to the discharge of volatile organic compounds, a PVC shower curtain printing company had installed a catalytic oxidizer. However, the low flow rates of the equipment resulted in high solvent concentrations within the workplace environment, causing worker discomfort. On investigation, solvent vapour concentrations were found to exceed NIOSH, OSHA and ACGIH acceptable exposure levels. The workers were required to wear organic vapour removing respirators full-time while printing. The company requested NIOSH assistance in finding methods to reduce solvent vapour concentrations. NIOSH recommendations included technical controls for the emissions and the use of substitute inks. The new ink system and controls allowed the removal of the requirement for the treatment of discharged air, and the substantial increases in dilution ventilation thus achievable reduced worker exposures and waived the requirements for respirator usage.
