Title Method for determining dust emissions and for optimising local exhaust ventilation of harmful substances on machinery and plant
Original title Methode zur Ermittlung staubförmiger Emissionen und zur Optimierung der lüftungstechnischen Erfassung von Schadstoffen an Maschinen und Anlagen [in German]
Bibliographic information Zentralinstitut für Arbeitsschutz, Gerhart-Hauptmann-Strasse 1, 8020 Dresden, German Democratic Republic, 1981. 69p. Illus. 20 ref.
Abstract This brochure gives an introduction to the collection of dust and harmful substances and the theoretical principles of collection: exhaust hoods and apertures, exhaust slots, push-pull ventilation systems, air speed. Following a review of the main rules to be observed in the design of ducting for air containing harmful substances, consideration is given to the characteristics of gas, dust and liquid separators (mechanical, filters, electrostatic, scrubbers). Portable test equipment for determining dust emission at source and the necessary minimum exhaust air speed are described: equipment, functional diagram, mode of operation, analysis of measurement results. Practical examples of the use of this equipment in the control of dust given off by mixing drums in the pottery industry.
