An on site visit was made to the Baker Furniture Company (SIC-2435, 2436), Mocksville, North Carolina to observe the processes and associated controls for veneering wood panels using heated platen presses. The facility manufactured furniture, and produced veneered panels. For flat panels, the hot press process was used exclusively. There was some radiofrequency (RF) laminating of small parts and frames. Less than 5000 square feet of panels were produced per day. The veneer department consisted of 35 workers, eight assigned to the hot press operation. For most applications a urea/formaldehyde resin was used as the adhesive. There were canopy hoods over the feed through press and the shuttle press. General ventilation was provided mainly by open doors and an extensive local exhaust ventilation for controlling sawdust. Formaldehyde (50000) concentrations ranging from less than 1 part per million (ppm) to between 1 and 2ppm were noted around the feed through press in the morning. Concentrations of 1 to 3ppm were noted at the glue mixing station, loading platform, and unloading area in the afternoon. The general airflow through the space between the press and face of the canopy appeared to carry some emission into the work place. The author notes that this facility offers the opportunity to study a canopy hood over a feed through press, but the low production rate may preclude an accurate evaluation of control system effectiveness.
