Preliminary survey report: control technology for formaldehyde emissions at Jasper Laminates, Jasper, Indiana, report no. 108-29a.
NIOSH 1983 Jul; :1-9
An on site visit was made to Jasper Laminates (SIC-2435, SIC-2436), Jasper, Indiana, to observe the processes used in veneering wood panels by a heater platen press method, and methods of controlling formaldehyde (50000) emissions. The facility produced panels for pianos, organs, office furniture and other wood products, using primarily the hot press process along with some radiofrequency (RF) pressing of curved panels and small parts. The glue most often used was a urea/formaldehyde resin adhesive. The hot presses were located under one large ventilated enclosure, measuring about 20 by 150 feet. There were also eight ventilation fans in the ceiling and auxiliary fans used to provide additional cooling air for workers and for the caul plates. Therefore, the primary methods of controlling formaldehyde exposure were dispersion, using auxiliary fans, and area ventilation. No partial shift time weighted average formaldehyde concentrations were measured at over 1 part per million (ppm). For two workers unloading different hot presses, short term breathing zone concentrations occasionally reached 2ppm. The author concludes that this facility offers the opportunity to study large scale area ventilation with passive make up air supply, and the appropriate use of auxiliary fans.
