In-Depth Survey Report: Control Technology for Formaldehyde Emissions at Dixie Furniture Plant, Lexington, North Carolina

摘要

An indepth survey of control technology for reducing exposure to formaldehyde (50000) at Dixie Furniture Factory (SIC-2435, SIC-2436), Lexington, North Carolina was conducted. Area and breathing zone samples were analyzed for formaldehye. Engineering controls consisted of general and local exhaust ventilation in the pess roomand at the large and small ten opening presses, and isolation and local exhaust ventilation at the radiofrequency (RF) press. The author notes that although the engineering controls reduced TWA formaldehyde concentrations to below the OSHA standard, some short term samples showed that peak exposures were not as well controlled. Some peak exposures were as high as 10ppm. Recommendations include relocating supply air vents, and automating mechanisms on the presses to reduce short term exposures.
