This photograph showed a Centers for Disease Control and Prevention’s (CDC) scientist, as she was in the process of pipetting specimens in a Biosafety Level-4 (BSL-4) laboratory, located in Atlanta, Georgia. The scientist was wearing a protective airtight suit, equipped with a helmet and face mask. She was seated at a negatively pressurized flow hood that allowed no air to flow back into the lab environment. Using this negatively pressurized, hooded environment any airborne pathogens, or toxic vapors, were drawn back into the hooded cabinet, and up into a filtered ventilation system, thereby, avoiding the spread of contaminants through the laboratory.
