Walk-Through Survey Report: Control Technology for Wood Lamination Presses at Jasper Wood Products, Jasper, Indiana, Report No. CT-108- 29a.
NIOSH 1983 Mar:14 pages
A visit was made to Jasper Wood Products (SIC-2435, SIC-2436), Jasper, Indiana for the purpose of including this company in an in depth study of formaldehyde control methods during the manufacturing of wood products. There were 85 production workers, 11 in the hot press area and three in the radiofrequency (RF) molding press area. Parts for furniture, cabinetry, and musical instruments such as drums, violas, and harps were manufactured. The site had a 150,000 cubic feet per minute local exhaust system for the wood machining tools and additional exhaust fans in the press department. Temperature was maintained at 70 degrees. About 25,000 to 30,000 square feet of laminated panels were produced per day. Only one of two hot presses was operated at any one time. They occupies a room with a ceiling enclosure and three roof exhaust fans. The six RF presses were located in a wire mesh enclosure to contain stray RF emissions. This area was ventilated by two wall exhaust fans. The adhesive used for both press operations contained 2 to 3 percent formaldehyde. An additional control method was the addition of a glue formulation fume suppressant. Breathing zone formaldehyde concentrations were all within the 1.12mg/m3 range for hot press workers and the readings for the RF drum press operators was only slightly higher. Area samples were below the limits of detection except for a 0.4mg/m3 reading at the RF press instrument back control panel sample and a 0.3mg/m3 reading taken outside the ceiling enclosure on the take off end of the hot press.
