A survey to assess the techniques used to control occupational exposure to formaldehyde (50000) was conducted at the Hillcrest Veneer Factory (SIC-2435, SIC-2436), High Point, North Carolina, in September 1982. The control systems at the facility were found to be effective. None of the area or breathing zone time weighted average formaldehyde concentrations exceeded 0.5 parts per million (ppm). Continuous and short term sampling showed that peak exposures were well controlled, none exceeding 3ppm. The low concentrations were achieved by combination of an area and local exhaust ventilation system that exhausted 93000 cubic feet per minute (ft3/min) air from the press room, with a supply air system that infused approximately 18000ft3/min fresh air into the primary work area of the press workers. Each press was partially enclosed and fresh air was directed into the press areas from specially positioned overhead outlets. In addition to cleansing the work area with fresh air, the outlets pushed air toward the local exhaust ventilation inlets while reducing the heat in the press area. The author suggests that research be done to determine the optimal configuration of the fresh air outlets. The control system at this facility is efficient.
