Studies the ventilation of 9 air-conditioned animal rooms used for both housing and experiments. Samples dust, measures ventilation rate by anemometers and by tracer gas decay, and uses settle plates to determine the number of airborne bacteria. Detects a high amount of pariculate matter emanating from the animals which might sensitize personnel working in these rooms.
