Description:

This historical photograph, provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), depicted an overhead Kirk & Blum Co. exhaust ventilation hood, in the 'On' position, inside the Cincinnati, OH, William Powell Valve Co. factory. Note the pressurized gasses being expelled from the chamber beneath the hood, which were being drawn up into the unit's overhead exhaust system. It was not known from this image whether or not these gasses were toxic, or noxious. See PHIL #9641 for another view of this scenario, however, in that view, the vent was in the 'Off' position, and was not ingesting the expelled fumes.
