What type of access does a man hole cover provide?

A manhole cover provides vertical access because it is designed to allow entry to the underground space below. This vertical access enables workers to enter and exit the manhole, which typically leads to utility systems such as sewer lines, water mains, or electrical conduits. The structure of a manhole is cylindrical, and the cover sits horizontally on top, facilitating direct upward and downward movement to and from the access point.

While the other access types may be related to various entry points or situations, a manhole cover specifically facilitates movement directly vertical, making it essential for tasks such as maintenance and inspection of underground facilities.
