Manhole closings are protected by a manhole cover (also known as a "biscuit"), a flat plug designed to prevent accidental or unauthorized access to the manhole. These covers are traditionally made of metal, but may also be constructed from precast concrete, glass reinforced plastic, or other composite materials.
Manholes are usually outfitted with metal, polypropylene, or fiberglass steps for easy descent into the utility space. European legislation has led to the use of lighter weight composite materials for manhole covers, offering benefits such as greater slip resistance and electrical insulating properties.
The circular shape of the access openings prevents accidental falls of the cover into the hole. Manholes are commonly found in urban areas, on streets, and occasionally under sidewalks. In rural and undeveloped areas, services like telephone and electricity are often carried on utility poles or pylons instead of underground.
