Abstract
An indepth survey of control technology was conducted at Honeywell, Incorporated (SIC-3822), Minneapolis, Minnesota in August 1980 to evaluate engineering control technology used in a captive plating and cleaning operation. The cleaning tank and two electroplating tanks in the manual chrome (7440473) (Cr) line were studied. The cleaning tank contained a solution of sodium-hydroxide (1310732) (NaOH) and was equipped with a lateral exhaust ventilation system and cover. The plating tanks contained chromic-acid and were ventilated using a push pull technique. Dummy loads were inserted in the chrome line tanks to simulate operations. Area air samples were collected and analyzed for NaOH, hexavalent-chromium (18540299) (CrVI), and sulfuric-acid (7664939). Personal samples were analyzed for copper (7440508), cyanide (74908), nickel (7440020), and silver (7440224) from plating operations. The chrome plating tank with push/pull ventilation showed inadequate control of CrVI emissions. Personal samples yielded low concentrations of cyanide, copper, nickel, and silver. Acid cleaning tanks were well controlled with local exhaust ventilation. The authors conclude that health hazards in the plating areas are well controlled. They recommend that ventilation be improved at the chromic-acid plating tank, and exhaust hoods and ducts be cleaned and repaired more frequently.
