Abstract: A containment system for biohazardous fluids is described. The containment system operates under the action of gravity at substantially constant atmospheric pressure. The system includes a container having a first membrane and a second membrane coupled together to enclose a containment volume. The first membrane is characterized by being permeable to gases and impermeable to liquids and aerosols. The second membrane is characterized by being impermeable to gasses and liquids and includes an inlet port configured to receive a tube. A self-sealing inlet port minimizes splashing back and spillage. Particular embodiments include a single-use liner assembly and a rigid, reusable receptacle with a securable lid and a drain for disposing of collected fluids. The receptacle may be coupled to the liner assembly to substantially enclose the liner.
