Title Development of tracer gas methodologies for the evaluation of the performance of ventilation systems in various workplaces
Original title Mise au point de méthodes utilisant un gaz traceur pour déterminer le rendement de systèmes de ventilation dans divers milieux de travail [in French]

Abstract Tracer gas methods developed to date allow an assessment of the total performance of ventilation systems in workplaces which is, in many ways, superior to that afforded by conventional tools such as the Pitot tube and anemometer. These methods have been used to determine the efficacy of contaminant removal, the recirculation of contaminated air, the migration of pollutants in the work environment and their migration to adjoining work areas, air leakage in office towers, and local air exchange rates. Although it is anticipated that tracer gas methods will be available to most industrial hygienists and technologists in the near future, certain impediments exist to their universal acceptance. The methods and their ancillary techniques require optimization and normalization. This article presents a summary of the state of the art for this methodology and of progress achieved in making these methods more acceptable. Air sampling and sample analysis are identified as two essential elements of tracer gas methodology which require further work.
