| 1. An electrically conductive confined space ventilator conduit, comprising:
a hollow first section having other than a full circle shape in cross section, said first section being formed of a conductive
plastic material, wherein said confined space conduit can be used to ventilate an enclosure via mounting in a port to the
enclosure with less obstruction of the port than if said first section had a hollow full circle cross section of equal area,
wherein upon connection of said conduit to a ground connection device said conduit will conduct static charge to ground upon
connection of the ground connection device to ground.
