Preliminary survey report: control technology for formaldehyde emissions at Hoosier Panel, New Albany, Indiana, report no. CT-108- 23a.
NIOSH 1982 Dec; :1-10
An on site visit was made to the Hoosier Panel Company (SIC-2435, SIC-2436), New Albany, Indiana to observe processes and controls in the veneering of wood panels. Most of the bonding of the veneer to the core was accomplished through use of a urea/formaldehyde resin and a hot press method. Some work was done using a cold press process in which the glue was heated with radiofrequency radiation. Banding of the core with solid wood edges prior to veneering also used an adhesive which may contain formaldehyde. At least five different recipes were used for panel glue, all of which involve the Perkins L-100 urea/formaldehyde resin. A canopy hood was installed over each press and extended 10 to 12 inches beyond the sides of the press. There were six wall fans in the plate cooling rooms. Airflow across the glue room was also aided by auxiliary fans positioned throughout the room coupled with open doors and windows. Routine air sampling was not performed. Some of the workers wore gloves and aprons while others wore goggles as well. A safety committee inspected the site monthly. The local exhaust ventilation hoods had an insufficient flow rate to capture vapors beyond the boundary of the canopy openings. This facility offered a unique approach to caul plate cooling which also provided a large quantity of the general ventilation airflow. The author recommends that the auxiliary fans might be better positioned to contribute more effectively to controlling exposures.
