Final answer:
The correct type of Biological Safety Cabinet for handling hazardous drugs is a Class II vertical cabinet that meets at least ISO Class 5 conditions to ensure a safe environment for personnel and the containment of harmful agents.
Step-by-step explanation:
A Biological Safety Cabinet (BSC) for handling hazardous drugs should be a Class II or III type. Specifically, a Class II BSC is designed with directional airflow and partial barrier systems to contain infectious agents, providing a significant level of safety for laboratory personnel, the environment, and the materials within the cabinet. It is also important to note that for BSL-2 laboratories, which handle agents such as Staphylococcus aureus and Salmonella spp., BSCs are an essential piece of equipment to prevent aerosolization of pathogens. For handling hazardous drugs, a BSC should be a vertical cabinet to ensure proper airflow patterns, and it must meet at least ISO Class 5 conditions, which corresponds to an environment with exceptionally low particles and contamination levels.
