Apparatus for venting chemical vessels

A workplace furnishing having an integrated venting apparatus, comprising:

• a frame having one or more surfaces for supporting one or more chemical storage vessels;
• a vent duct affixed to the frame;
• a plurality of vent ports in spaced-apart locations in the vent duct, wherein each of the vent ports is adapted for coupling to a chemical storage vessel;
• a flow control mechanism disposed in the vent duct downstream from the vent ports, wherein the flow control mechanism comprises a plate mounted perpendicularly within the vent duct and having a hole therein;
• and
• a damper disposed in the vent duct downstream from the vent ports.

A venting apparatus, comprising:

• means for conveying chemical vapors from an internal environment to an external environment;
• means, disposed in spaced-apart locations in the conveying means, for coupling the conveying means to one or more chemical storage vessels;
• means disposed in the conveying means, downstream from the coupling means, for controlling a flow of the vapors from the internal environment to the external environment, wherein said controlling means comprises a plate mounted perpendicularly within the vent duct and having a hole therein;
• and
• means disposed in the conveying means downstream from the coupling means for damping the flow of the vapors.

A venting apparatus, comprising:

• a vent duct;
• a plurality of vent ports in spaced-apart locations in the vent duct, wherein each of the vent ports is adapted for coupling to a chemical storage vessel;
• a flow control mechanism disposed in the vent duct downstream from the vent ports;
• a damper disposed in the vent duct downstream from the vent ports;
• wherein the vent duct comprises a generally vertical exhaust duct section, and a vent header, wherein the exhaust duct section is joined substantially perpendicularly to the vent header;
• wherein the flow control mechanism and the damper are in the exhaust duct section;
• wherein the vent ports are in the vent header;
• and
• wherein each of the vent ports comprises a bulkhead union mounted perpendicularly in the vent header and having a hole therein.
