Abstract

Tracer gas techniques are widely used to determine the capture efficiency of local exhaust hoods and the contaminant removal effectiveness of ventilation systems in general. In these applications the generation of actual contaminants is simulated by tracer gas release. Correct simulation can be presupposed if the behaviour of the tracer gas released corresponds to the maximum extent of the actual contaminant generation process. The aim of this study was to ascertain to what extent generation and dispersion of styrene vapours can be simulated by tracer gas release in the manufacture of reinforced plastic products. It was observed that the generation of styrene vapours may be simulated by tracer gas in hand lay-up moulding and spray-up moulding, assuming that the evaporation of styrene is negligible during the curing phase.
