Abstract : A small test chamber was used as a model enclosed space to study the removal of irritant vapours by ventilation. Quantitative data was obtained on the relative rates of removal of CH and CN and their adsorption/desorption rates from selected materials. Triethyl phosphate, a liquid of intermediate volatility, was included in the study for comparison purposes. Ventilation removal rate data for the chamber was compared to data for ventilation trails carried out using a one-room building. Under the given experimental conditions, results obtained form experiments with the model enclosure allow qualitative predictions to be made of vapour removal rates for the other enclosures based on air exchange rates, vapour concentration decay half-lives, mixing factors and relative volatility of the vapour source.
