Description:Depicted in this 2007 photograph was Centers for Disease Control and Prevention (CDC) biologist Shon Workman, working in a Biological Safety Cabinet (BSC), conducting a test in order to validate a rapid HIV nucleic acid extraction and amplification process. The BSC provides a negatively-pressurized experimental setting under this flow hood, which allows no air flow to escape back into the laboratory. Using this negatively pressurized, hooded environment any airborne pathogens, or toxic vapors are drawn back into the hooded container, and up into a filtered ventilation system, thereby, avoiding the spread of contaminants throughout the laboratory.
