ABSTRACT:
An anesthesia waste gas evacuation system having a waste gas collection chamber with an inlet into the chamber at the bottom and a blower at the top for blowing gas from the chamber to an outlet connected to a building ventilation system. Vents are provided to provide communication between the chamber interior and the surrounding atmosphere so that the pressure within the chamber remains substantially at atmospheric pressure avoiding the formation of a sub-ambient pressure within the chamber. The chamber is electrically grounded and is electrically connected to a standpost so as to ground the post as well.
