Abstract
An indepth control technology survey was conducted at Greensboro Industrial Plating (SIC-3471), Greensboro, North Carolina in January 1981 and November 1981. The survey was conducted to assess occupational health problems through the application of control technology. Air samples were collected and analyzed for hexavalent- chromium (18540299) (CrVI) and sulfuric-acid (7664939). Ventilation measurements were taken. Employee exposures to CrVI ranged from weighted average (TWA). The mean exposure for the three workers was of 0.100mg/m3 for an 8 hour TWA. NIOSH recommended limit for CrVI was 0.025mg/m3 for an 8 hour TWA. For sulfuric-acid, exposures ranged between 0.107 and 0.967mg/m3 with a mean of 0.327mg/m3 for an 8 hour TWA, compared with OSHA PEL of 1.0mg/m3. Double sided draft ventilation hoods and three sided hoods were used for contaminant control, the former being more effective. Recommended exhaust rate was 250 cubic feet per minute per square foot. Only one of the tanks approached that rate. The author concludes that employee exposures are within OSHA and NIOSH recommendations. Higher exhaust rates may be required for higher production rates.
