Manhole depth: a maximum depth of 20 feet is specified in order to comply with department of labor and industry ladder safety regulations. Manholes that exceed this depth must be designed with an appropriate safety feature, such as a landing platform or ladder safety device.

Manholes are found in a variety of locations, such as along sidewalks, in parking lots, and in the middle of streets. They are often used to access underground utilities, such as water and sewer lines.
