Title Evaluation of local exhaust equipment by determination of the air flow by a propane tracer method
Original title Bestimmung des Abluftstromes nach der Propan-Tracer-Methode - Beurteilung von Absauganlagen [in German]
Bibliographic information Dec. 1977, Vol.37, No.12, p.462-464. Illus.
Abstract Description of the principle and measuring equipment: air volume, calculation of exhaust rate, determination of harmful gas concentration in the breathing zone and the workshop. The method, which is based on the use of propane as tracer gas and a flame ionisation detector, was used to study working conditions in hot-box coremaking in a grey-iron foundry. It permits determination of the interference of other equipment and improvement of the exhaust system.
