Final answer:
The flow hood suitable for compounding chemotherapy is the Biological Safety Cabinet, specifically the Class III version, which is completely sealed and integrates HEPA filters to maintain a sterile environment.
Step-by-step explanation:
The flow hood that is completely sealed and can be used to compound chemotherapy is the Biological Safety Cabinet (BSC). Specifically, the Class III BSC is designed for working with highly infectious agents and provides the highest level of containment. In the context of chemotherapy compounding, which requires sterile and safe environments due to the toxicity of chemotherapy agents, Class III BSCs are ideal because they are gas tight. Moreover, they incorporate HEPA filters to ensure a clean air environment by filtering both the intake and exhaust air to prevent contamination and exposure to hazardous materials. Materials enter or exit the cabinet through a double-door system that allows for decontamination, ensuring a secure and sterile processing area.
