This historic image, depicted a laboratorian, as she was seated at a negatively pressurized laminar flow hood, while she was in the process of what appears to be the inoculation of slant culture test tubes. She was wearing a disposable gown, gloves, and facemask, but no eye protection, which is now considered essential personal protective equipment (PPE). The negatively pressurized flow hood prevents air from flowing back into the lab environment, thereby, preventing airborne pathogens, or toxic vapors, released inside the hood, to be drawn back into the hooded container, and up into a filtered ventilation system.
