title: A method for biological testing of containment systems for viral agents.
abstract: A technique utilizing coliphage as the test material has been developed and employed to evaluate the effectiveness of a containment system for zonal centrifugation of hepatits viruses. An Andersen Viable Particle Sampler which had been loaded with plates containing a base layer of agar nutrient with an overlay of E. coli- agar suspension was used to sample the test air. The containment system, which includes a HEPA filter, was challenged with an aerosolized suspension of coliphage.
