Claim:
A manhole cover for use in covering a manhole ring having a rim and a lip, said manhole cover comprising: a support having an upper surface, said support comprising a plurality of passageways therethrough; an outer thermally and electrically insulating member disposed over the entire upper surface of said support and between said passageways of said support, said support comprising a first material, and said outer insulating member comprising a second material different from said first material; wherein a peripherally-extending portion of said support is positionable over the lip of the manhole ring and spaced adjacent to an inner surface of the rim of the manhole ring, and said outer insulating member is positionable between said upper surface of said support and the upper surface of the rim of the manhole ring when the manhole cover is received in the manhole ring; and wherein said outer insulating member is operable to provide said manhole cover with a reduced likelihood of thermal and electrical burns and electrocution upon contact compared to contact with a conventional metal manhole cover.
