Preliminary survey report: particleboard and plywood plants, Springfield Wood Products Facility, Weyerhaeuser, Inc., Springfield, Oregon, report no. CT-108-19a.
NIOSH 1981 Dec; :1-12
An on site visit was made to the Springfield Wood Products Facility (SIC-2436, SIC-2492), Springfield, Oregon, to observe the application of adhesives during the manufacturing of furniture products. All processes needed to take felled trees and process them into finished wood products were performed on site, including the production of particleboard and plywood products. Resins used at the site include methylene-bisphenyl-isocyanate and polymethylene- polyphenyl-isocyanate. Control measures included curtains hung around the particleboard press and the board/caul plate separator which effectively contained the rising, heated emissions from these operations for removal by the roof fans above these areas. A detector tube near the press indicated less than 0.5 parts per million (ppm) formaldehyde (50000) concentrations in this area. The board cooler and cooling tunnel was built onto the outside of the particleboard facility. Roof fans were located above the presses in the plywood facility. Workers handling the plywood wore gloves to protect them from splinters and from phenolic resin. Hearing protectors and safety glasses were required on some jobs. Respirators were available. While there were pockets of air in which the formaldehyde odor was stronger than the mild ambient level, the concentrations at this workplace were deemed to be low. The author indicates that, if the wood products industry is selected for in depth study, this facility should be a prime candidate for a detailed survey.
