• Description:
  An indepth survey of control technology at a Trans World Airlines maintenance facility (SIC-0471), Kansas City, Missouri was conducted in October, 1981. Environmental and breathing zone samples were analyzed for hexavalent chromium (18540299), sulfuric-acid (7664939), silver (7440224), copper (7440508), cadmium (7440439), nickel (7440020), hydrogen-fluoride (7664393), cyanide compounds, or tetrachloroethylene (127184) at the silver and copper strike bath tanks, the silver, nickel, cadmium/cyanide, and chrome plating bath tanks, the acid etch bath tank, and the vapor degreasing tank. Airflows of the local exhaust systems of the tanks were measured (except for the cadmium/cyanide plating and the tetrachloroethylene vapor degreasing tanks which did not have local exhaust systems) and the nickel plating tank, whose ventilation system was malfunctioning. The measured exhaust rates of the tank local exhaust systems were generally below the recommended values, ranging from 46 to approximately 80 percent of the recommended rates. The air concentrations of the contaminants were below OSHA standards except for area air tetrachloroethylene samples at the degreasing tank which averaged 77 to 1,528 milligrams per cubic meter (mg/m3). The OSHA standard for tetrachloroethylene is 678mg/m3. Although ventilation rates were generally below recommended values, air contaminant concentrations were generally below OSHA standards.
