• Description:
  The ability of commercially available air filtering cleaners to control mist emissions and reduce the exposure of workers to mist was evaluated at Sauer-Sundstrand Company, Ames, Iowa. The company produced transmissions for off the road vehicles. Air cleaners had been installed in one shop area. Triethanolamine (102716) (TEA) was the major component of the synthetic metal working fluid (MWF) used. Relatively low concentrations of total particulates and TEA were identified. With both substances the highest concentrations were found near the hydromation (central cleaning) unit, which was causing significant emissions of MWF into the air of the facility. The effectiveness of installing air cleaners on the machining centers and improving mist control on the hydromation unit was demonstrated. TEA concentrations were reduced four to 10 fold. The total particulate concentrations were reduced 16 fold near the hydromation unit. Some major sources of contamination remained including older machining centers which were not well enclosed. The authors conclude that installation of air cleaners resulted in a significant reduction of the TEA and total particulate concentrations.
