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.
Due to legislation restricting manual handling weights, there has been a shift towards lighter weight composite materials in Europe. These materials offer 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 rather than underground.
