NIOSH technical report: control technology assessment: metal plating and cleaning operations.

Abstract

A control technology assessment of electroplating and cleaning operations was conducted by the National Institute for Occupational Safety and Health (NIOSH).Walk-through surveys were conducted at about 30 electroplating plants and 9 in-depth studies at 8 plants. Air sampling and ventilation data and other control information were collected for 64 plating and cleaning tanks.Thirty-one of these were hard chrome plating tanks but cadmium, copper, nickel, silver, and zinc plating tanks were also evaluated.Acid, caustic and solvent cleaning tanks were also evaluated. Worker exposures were found to be controlled below existing and recommended standards. i11
