Title Research on improved shields for welders to avoid inhalation of fumes, gases and vapours
Original title Untersuchungen zur Verbesserung von Schutzschirmen und Schutzschilden für Schweisser, um das Einatmen von Rauchen, Gasen und Dämpfen zu vermeiden [in German]
Bibliographic information Deutscher Verlag für Schweisstechnik GmbH, Postfach 2725, 4000 Düsseldorf, Federal Republic of Germany, 1981. 43p. Illus. 19 ref. Price: DM.8,50.
Abstract This research report on the humanisation of work sets out the methodology and results of laboratory investigations to determine the optimal shape of shields (attached to helmet, or hand-held) for protection against welding gases and fumes. Results of observations of aerodynamic fume behaviour and currents (by cinematography) and gas analysis enable a better choice of shields to be made. Fume deflection was improved by 25%, and only 2% of the fumes entered the welder's breathing zone.
