The method of claim 6 wherein the flange separator forming step includes forming an angled taper at an end of each of the pair of elongated flange plates opposite the end with the threaded opening wherein, when the pair of elongated flange plates are located adjacent to and contact each other, the combination of the ends with the angled taper of each of the pair of elongated flange plates forms a wedge for inserting between the manway cover and the manway flange. 11. The method of claim 1 wherein the flange hinge plate and the cover hinge plate connecting step includes forming an elongated opening in each of the transverse plate flanges that extend in the same direction from opposite ends of the cover hinge plate and wherein each of the transverse plate flanges matingly receives one of the transverse plate flanges of the flange hinge plate, the transverse plate flanges of the flange hinge plate having a pivot receiving opening and which extend in the same direction from opposite ends of the flange hinge plate, and inserting a pivot post into the elongated opening and the pivot receiving opening that are matingly received to each other. 12. A method of handling the removal and installation of a manway cover to a manway flange, the method comprising: removing a plurality of manway cover bolts from a first portion of the manway cover that is located to one side of a vertical axis of the manway cover exposing the manway cover bolt openings and the manway flange bolt openings aligned therewith; removing a plurality of manway cover bolts from a second portion of the manway cover exposing a plurality of manway cover bolt openings and flange bolt openings aligned therewith; inserting at least one extended length cover supporting rod into one of the plurality of manway cover bolt openings of the second portion that are exposed by the removal of the plurality of manway cover bolts; providing end stops at each end of the cover supporting rod; removing the remaining manway cover bolts from the manway cover; separating the manway cover a predefined distance from the manway flange, the manway cover being supported by the at least one extended length cover supporting rod; providing a flange hinge plate of a portable manway cover hinge device, the flange hinge plate having at least one hinge plate aperture therethrough; aligning the at least one hinge aperture of the flange hinge plate with a bolt opening in the manway flange; inserting a pin first end of a hinge plate fastening pin through the at least one hinge aperture and into the aligned bolt opening in the manway flange; securing the flange hinge plate to the manway flange; providing a cover hinge plate of a portable manway cover hinge device, the cover hinge plate having at least one hinge plate aperture therethrough; aligning the at least one hinge aperture of the cover hinge plate with a bolt opening in the manway cover; inserting a pin first end of another hinge plate fastening pin through the at least one hinge aperture and into the aligned bolt opening in the manway cover; securing the cover hinge plate to the manway cover; pivotally connecting the flange hinge plate to the cover hinge plate; and removing any remaining manway hardware from the manway cover and the manway flange that prevents the manway cover from pivotally opening away from the manway flange. 13.
