      <subfield code="a">The common practice in industrial hygiene is to use dilution ventilaton. Increasingly displacement ventilation, which ideally supplies fresh air that displaces the contaminated air without mixing, is being introduced. By means of an intervention study at an electroplanting plant the relative performance of the two principles of design was evaluated using an experimental signal-response tracer gas technique. The theoretical framework is summarized</subfield>
