Control of wood dust from disc sanders.

An evaluation was conducted to develop a control system to reduce wood dust emissions from disc sanders. A system to assist in jet stripper ventilation was developed. This auxiliary system was used in combination with existing local exhaust control and was located inside the exhaust hood. The system consisted of a set of jets uniformly located along the main axis of the manifold supplying the pressurized air. The system can be used at disc sanders with different sanding disc diameters. When combined with local exhaust the device reduced total wood dust content in the disc air layer by over 90%, resulting in an average reduction in the area and breathing zone samples of wood dust emissions by 60%. Verification of the laboratory data on performance of the jet stripper was obtained in a field test conducted on an industrial 91.4 centimeter disc sander. Personal wood dust exposure was reduced by 50% or more. The ventilation system did not interfere with the operator's activity and was inexpensive to install and operate.
